And, in our second semi-final, Bath reached their first Premiership final since 2004 with an emphatic win over rivals Leicester Tigers.
A brace from Matt Banahan and a Kyle Eastmond try put the home side in control, despite ending the first half with 13 men when Tom Youngs replied.
Second-half tries from Peter Stringer, George Ford and Anthony Watson sealed Bath's passage to Twickenham as Banahan completed his hat-trick late on.

Earlier this afternoon, Saracens reached the Premiership final after beating Northampton in a pulsating match at Franklin's Gardens.
Owen Farrell's late penalty secured victory over Saints, who had finished the season at the top of the table.
The visitors took an early lead through David Strettle's converted try but Northampton, the 2013-14 champions, fought back to level by half-time.
Jamie George's try helped Saracens carve out a five-point lead and they held on to reach Twickenham.

Saracens director of rugby Mark McCall revealed after his side's semi-final win over Northampton that his team had defied a sickness bug that had swept through the squad.
Prop Shalk Brits wasn't fit enough to make the bench, while wing Chris Ashton recovered to take his place among the replacements.
"We had a mass of sickness around the squad this week. Schalk Brits was in hospital for two days and lost seven or eight kilograms," said McCall.
"There were 10 other people who had it, but you wouldn't have known. Chris Ashton was among the worst and Brad Barritt has been in a mess, but you wouldn't have been able to see that.
"You add the bug to the occasion and it tells you the sort of group we have."

Northampton director of rugby Jim Mallinder said:
"We knew what their plan would be and they did what we expected, but they do it very, very well.
"At the breakdown they were physical. Those Vunipola brothers.... once they get over the ball their stomachs are touching the ground already. It's near impossible to move them.
"Everyone decides how they want to play and Saracens have gone down their route. That's the game.
"They do it very, very well. To become champions you have to beat all styles and we didn't get over this hurdle."

Leicester Tigers director of rugby Richard Cockerill told BT Sport: "That was nothing to be ashamed of. I think we've worked really hard, and there's still a lot of quality players missing out of that side. But I've got nothing but praise for the players. It's been a tough year all round. There's no disgrace in the result today."

Bath head coach Mike Ford told BT Sport: "We scored a couple at the end there which probably skewed the score a little bit. I thought our defence was outstanding. But they didn't really have a bench like ours, and we knew that. Once we got that fourth try we settled down and ran away with it a little bit."

Bath fly-half George Ford told BT Sport: "I think in these play-off games, when you get opportunities in the red zone you have to take them. To get seven tries is pleasing, but I'm not sure it'll be like that again next week."
Post update
FT: Bath 47-10 Leicester
Bath fly-half George Ford told BT Sport: "It was anything but easy. We had to defend for long periods of time. To be fair, the boys kept putting their bodies on the line and we got a few tries from turnovers at the end there. The score probably doesn't reflect how the game was."

Banahan, for the record, became the first player in Premiership play-off semi-final history to score a hat-trick of tries.

If you hadn't guessed already, Bath are heading to Twickenham! They will take on Saracens in next Saturday's final at Rugby HQ.
Try (Watson, con Ford)
Bath 47-10 Leicester
And there is the cherry on top of the Blue, Black and White icing on Bath's cake.
Carl Fearns puts in a monster hit on Julian Salvi on halfway and, within the blink of an eye, Anthony Watson streaks clear of the Tigers defence for Bath's seventh try. Just emphatic.
The conversion from George Ford even means the hosts trump the 45 points they stuck on Leicester back in September.
Post update
Bath 40-10 Leicester
Leicester have fought so hard for so long, but have fallen apart a bit here. Anthony Watson and Matt Banahan team up yet again to take Bath forward on the break, but George Ford's kick through drifts out of play and means, for the first time, the home side have entered the Leicester 22 and not scored.
But Bath are just too sharp, too clinical and, dare I say it, too good.
The Blue, Black and Whites break from inside their own 22, Anthony Watson's turn of pace takes them deep inside the Leicester half and Matt Banahan sails over the line for his hat-trick and Bath's sixth try.
George Ford's conversion extends the lead to 30 points. Has this really been a 30-point match?!
Post update
Bath 33-10 Leicester
Full credit to Tigers, still they knock on the Bath door, but still the hosts refuse to let them in. Another JP Doyle blow of the whistle means another Leicester penalty, however, so we're back into touch.
Replacement
Bath 33-10 Leicester
Peter Stringer, playing at The Rec for the final time, is given a wonderful ovation as he's replaced at scrum-half by Chris Cook. Leicester, meanwhile, are up to the Bath five-metre line and win a penalty for their troubles too.
Post update
Bath 33-10 Leicester
For those still keeping count, that is indeed five visits to the Leicester 22 and five Bath tries. Tigers are fighting until the very end here though, as you'd expect them too, as Brad Thorn launches himself into a couple of Blue, Black and White tacklers.
Post update
Bath 33-10 Leicester
Steve Johnson
Ex-Tigers captain on BBC Radio Leicester
"Leicester have had about 70% of the possession and 70% of the territory and they are on the end of a hiding. Bath haven't had much possession but every time they had had it they've scored."
Try (Ford, missed con Ford)
Bath 33-10 Leicester
PACopyright: PA
If they weren't already, Bath are definitely heading to Twickenham now!
So simple, but so effective from Mike Ford's men. Semesa Rokoduguni gets clear down the right, draws the tackle and offloads to George Ford, who runs through from around 15 metres out. The Premiership Player of the Season misses the conversion this time - but the home side are running riot at The Rec.
Post update
Bath 28-10 Leicester
This has just not been Leicester's day. Niki Goneva and then Christian Loamanu both knock the ball on in the same passage of play and Bath have a scrum. A cutting edge is all that's separated these two teams.
Post update
Bath 28-10 Leicester
Steve Johnson
Ex-Tigers captain on BBC Radio Leicester
"Leicester have only got themselves to blame. They have missed four kicks at goal and they have lived in the Bath half of the field. That is Bath's first excursion into the Tigers half in the second half and that is another try for Bath."
Try (Stringer, con Ford)
Bath 28-10 Leicester
Getty ImagesCopyright: Getty Images
This is quite unbelievable. I make that four visits to the Leicester Tigers 22 - and four tries scored by Bath. After securing good line-out ball, Francois Louw wriggles clear and tees up Peter Stringer, who touches down from close range.
Has the 37-year-old former Ireland scrum-half sent Bath to Twickenham? The two points added by George Ford from the tee would certainly add some weight to that theory.
Post update
Bath 21-10 Leicester
Now Niki Goneva is almost through down the left, but again the home side get back to him! And, as George Ford launches a counter-attack, Mathew Tait gives away a penalty and Bath are able to send the ball up-field. Breathing space for the Blue, Black and Whites.
Post update
Bath 21-10 Leicester
Having opted to boot the ball long via George Ford, Bath are defending once again. The sizeable frame of Christian Loamanu smashes through a couple of tackles to take Tigers into enemy territory, but replacement hooker Rob Webber does superbly to turn the ball over.
Post update
Bath 21-10 Leicester
Bath have made 92 tackles to Leicester's 42, which tells it's own story. Mike Ford's side have entered the visitors' 22 only three times in the opening 57 minutes - but have scored on each occasion.
Post update
Bath 21-10 Leicester
Leicester are working through the phases now, as this game starts to return to some kind of watchable structure at long last. But Bath have turned it over and look to run it from deep inside their own half.
Replacement

Sam Burgess's afternoon is over now, as he's withdrawn for Matt Garvey. He's not quite had the same impact here as he has done in recent weeks for Bath, now playing at flanker of course.
Post update
Bath 21-10 Leicester
After the breathless opening period, there's been absolutely no flow to this second half whatsoever. A couple of resets eventually lead to Leicester knocking it on after picking it up at the base of the scrum, meaning a further set-piece.
Replacement
Bath 21-10 Leicester
Huge cheers ring out around The Rec as captain Stuart Hooper is withdrawn. I wonder if he'll be leading his side out at Twickenham in the final next week? Not if Leicester have anything to do with it, as another knock-on means another scrum, which this time Tigers scrum-half Ben Youngs will insert.
Post update
Bath 21-10 Leicester
Steve Johnson
Ex-Tigers captain on BBC Radio Leicester
"Nothing is running for Leicester at this moment in time."
Post update
Bath 21-10 Leicester
As Bath clear the ball long, Leicester knock on, so we'll have a scrum. Tigers have generally had the better at the set-piece so far this evening - and it's another huge push which allows them to turn it over here too.
Post update
Bath 21-10 Leicester

This second half, with the injury to Niall Morris, just hasn't quite packed the same punch as the first. And that'll suit Bath, who were down to 13 and then 14 men for the first few minutes, and have now won a penalty after Jordan Crane was penalised for holding onto the ball on the floor.
Missed penalty (Bell)
Bath 21-10 Leicester
Tommy Bell takes over kicking duties from Freddie Burns then, but he misses the posts too. That's 12 points - enough to have Leicester in the lead - wasted from the tee now.
Post update
Bath 21-10 Leicester
Winger Matt Banahan, scorer of two of Bath's three tries, has gone in at number eight in place of Leroy Houston, who's still got another minute or so left in the sin-bin. And Leicester win a penalty from the scrum too - surely that wasn't Paul James again?!
Post update
Bath 21-10 Leicester
After a long pause in play, Niall Morris is at last withdrawn to warm applause from around The Rec. Despite this fierce rivalry, it's always good to see opposition fans recognise when a player is seriously hurt. Time for a scrum.
Replacement
Bath 21-10 Leicester
Tommy Bell comes on to replace Niall Morris, who missed a few months earlier this season with an ankle injury. The 26-year-old Irishman is lifted onto a stretcher.
Ouch!
Bath 21-10 Leicester
Now, that looks like a sore one for Niall Morris. He goes tumbling under Ross Batty's tackle, and is now receiving some treatment for an ankle injury. The Leicester man looks in a serious amount of discomfort.
Missed penalty (Burns)
Bath 21-10 Leicester

Freddie Burns can't land the kick though, so that's an early escape for Bath. Anthony Watson is back on the field, by the way, meaning the Blue, Black and Whites are back up to 14 men.
Kick-off
Bath 21-10 Leicester
Here we go then. Bath fly-half George Ford gets us under way - but his kick is not what he was looking for, and then Leicester win a penalty from the resulting scrum. An early chance for Freddie Burns?
Post update
HT: Bath 21-10 Leicester
The teams have returned to the field at The Rec. You'd imagine Leicester will be desperate to make the most of their numerical advantage, with Anthony Watson and Leroy Houston both in the sin-bin for Bath, at the start of this second half.

"When you look at the stats, Bath have been in the Leicester 22 on three occasions and scored three simple tries. Leicester have camped in the Bath 22 and have scored just one try. But that try means Leicester are back in the race."
Half-time
Bath 21-10 Leicester
A frantic, crazy, breathless 40 minutes of rugby union. But who expected anything different? Bath lead by 11 points at the break.
Try (Tom Youngs, con Burns)
Bath 21-10 Leicester
Ben HoskinsCopyright: Ben Hoskins
At last! Following the line-out, Leicester have the rolling maul in fine, working order, allowing Tom Youngs to peal off the side and bundle his way over. Freddie Burns's conversion is good, and Bath's resistance has been broken on the stroke of half-time. That should make Leicester director of rugby Richard Cockerill a little happier.
No try (Morris)
Bath 21-3 Leicester
Niall Morris has indeed dropped it, owing in part to some fine last-ditch defensive work from Semesa Rokoduguni. We'll go back for that advantage, however...

Oh dear, Bath are up against it all of a sudden. Leroy Houston is off to the bin this time, having landed himself in a slightly awkward position at the maul, and the home side are down to 13 men. Leicester will try a scrum this time.
Post update
Bath 21-3 Leicester
If ever a team needed a score, it's Leicester Tigers right now. Stuart Hooper is this time penalised following the line-out, prompting the visitors to head to touch once more...
Sin-bin (Watson)

But here come Leicester, who are having absolutely none of that kind of chat, immediately forcing Bath to backtrack. And, as they look desperate in defence, Anthony Watson infringes and is sent to the bin for his troubles too. Tigers head for touch.

Goodness me, this is absolutely brutal from Bath. George Ford's pass picks out Semesa Rokoduguni, who slips slightly before sending a grubber through to turn Leicester's defence. And now here comes Kyle Eastmond, in the right place at the right time, to cross the whitewash!
It's three conversions from three from George Ford too and, I know I promised not to mention that 45-0 again, but...
Post update
Bath 14-3 Leicester
Matt Banahan, one of only two Bath players to have featured last time they were in the play-offs in 2010, seems to have the Midas touch this evening. His long kick pegs Leicester back from the restart.
Try (Banahan, con Ford)
Bath 14-3 Leicester
PACopyright: PA
And, like a switch, Bath turn it on in emphatic style once again to stretch their lead. Jonathan Joseph is at the heart of it once more, sending Matt Banahan through out wide to cross in the corner. That is utterly ruthless from Mike Ford's side - whose advantage is extended further by George Ford's conversion.
Post update
Bath 7-3 Leicester
That seems to have sprung Bath back into action however, gathering the restart and immediately pinning Leicester back. Here's Sam Burgess now, taking the ball into contact, making some ground...
Penalty (Burns)
Bath 7-3 Leicester
Leicester are, at long last, on the scoreboard. It's third time lucky for Freddie Burns, who splits the post from 30 metres or so.
Paul James has come off, temporarily you'd have thought, for Nick Auterac meanwhile.
Post update
Bath 7-0 Leicester
Having secured good ball from the set-piece, Mathew Tait is again in the thick of things, releasing Julian Salvi out wide. The back-rower doesn't have the pace to wriggle clear - but he does do enough to win Leicester yet another penalty.
Paul James, all the while, is receiving some treatment to a nasty looking cut to the head.

Missed penalty (Burns)
Bath 7-0 Leicester
Freddie Burns, all of 47 metres from the posts, has a go but the ball comes back out off the upright. Niki Goneva is the man to gather it too, but Tigers concede a penalty and it's a real let off for Bath.
Leicester, make no mistake about it, are on top here.

But following wave after Leicester wave, Bath clear the ball long. Now, Ben Youngs attempts a box-kick on halfway only for Stuart Hooper to charge it down. The Bath captain sets off in pursuit of the ball, but he's penalised for offside and Leicester have a penalty.
Post update
Bath 7-0 Leicester
Tigers have the ball back once more, as Peter Stringer's touch-finder goes straight out of play. Richard Cockerill's side have responded superbly since Bath's fast start.

Freddie Burns kicks to touch then, and Leicester are on the attack from the set-piece. Mathew Tait, heading for Bayonne in the summer, takes the ball into contact but the home side are holding firm here. And this time the penalty is theirs too, as Ed Slater is penalised for holding on.
Post update
Bath 7-0 Leicester
The first one collapses, so referee JP Doyle asks the two packs to have another crack. The experienced Peter Stringer feeds it in for a second time - and Leicester have a penalty this time. There didn't look a huge amount in it, but it seems Dan Cole has got the better of Paul James on this near side and it's advantage Tigers at scrum time.

Leicester do well to turn the ball over and have it in hand again, although the returning Marcos Ayerza knocks it on and Bath have the put-in at our first scrum of the evening.

How about that for a start from the Blue, Black and Whites? It's vintage Bath as, following the set-piece, George Ford draws the tackle to release Jonathan Joseph, whose arrowed pass then picks out Matt Banahan on the wing to cross in the corner.
Ford's conversion, from the tightest of angles, is exquisite too and I'd imagine this is just how his father, head coach Mike, would've planned it.

That's an early error from the visitors, however, giving away a penalty following Freddie Burns' second long kick forward. George Ford goes to touch and Bath are on the attack.

Another fond farewell
Bath v Leicester (17:00 BST)
Getty ImagesCopyright: Getty Images
Following the flurry of fond farewells this time last week, with Sale winger Mark Cueto and London Welsh centre Tom May both bringing their playing careers to an end, we could have another one on our hands today.
At the ripe old age of 40, New Zealand World Cup winner Brad Thorn is in the Leicester Tigers side this afternoon - but is very much hoping to postpone his retirement by another 80 minutes.
"I feel so lucky and blessed but it would be great to push on for one more game and play at Twickenham," he told BBC East Midlands today. "It's a special place to play."
The Blue, Black and Whites need to be "mad for it" when they take on Leicester Tigers this afternoon, according to fly-half George Ford.
Ford is one of eight Bath players to be named in England's 50-man training squad for this year's World Cup - and each one of them will be hoping this won't turn out to be their last competitive action before the tournament kicks off on 18 September.
"These are the games you want to play in as a team and as individuals, and we're just looking forward to it," Ford told BBC Radio Bristol.
"Leicester are going to come here mad for it - and we've just got to be mad for it ourselves."

That 45-0 drubbing - and Tigers fans, I promise I'll try not to mention it again - was just one part of a pretty scratchy start to the season for Richard Cockerill's Leicester.
But don't they always just come roaring back when it really matters?
"I have always said it was about where we sit after round 22 - and we sit third," Cockerill told BBC East Midlands Today. "It doesn't matter where you are halfway through the season and you are sat in seventh or eighth and everybody has already made their mind up that it is a disaster.
"It's the end of the season that counts. We are the form team in the league in 2015, so there is some satisfaction in that."

How are we lining up then?
England centre Jonathan Joseph returns for Bath, who beat West Country rivals Gloucester on the final day of the regular season last week.
Head coach Mike Ford has also recalled captain Stuart Hooper, while Ross Batty comes back in at hooker.
Leicester Tigers make just one change from the side that earned an 11th successive appearance in the Premiership semi-finals by beating Northampton Saints.
Marcos Ayerza returns to the starting line-up at loose-head prop in place of the injured Logovi'i Mulipola.
And, speaking of previous encounters, if you're in Leicester's camp there is one that certainly does stick out like a very sore thumb from the rest.
Back in September, Bath ran out 45-0 winners against Richard Cockerill's side at The Rec, the heaviest top-flight defeat ever inflicted upon Tigers.
"It was not good," Lock Graham Kitchener told BBC East Midlands Today. "I tried to wipe it from my mind.
"For the boys who played in it was a bit of a turning point. We thought we can't go back to that. Everything that could have gone wrong did go wrong that day. It was bit of freak result."
A long-distance derby?
Bath v Leicester (17:00 BST)
Having first faced one another on Saturday, 13 September 1913, the century old rivalry shared between Bath and Leicester Tigers is one of the most famous in domestic rugby union.
A derby in every way apart from location, the two sides have played 26 times in the Premiership, with Tigers having won 16 and Bath only nine.
Mike Ford's side have, at least, come out on top in each of their last four meetings at The Rec though, so maybe the omens aren't all bad for tonight's hosts.

Jason Stone: Play-offs: Is it right? Saints top most of the season, Sarries scrape into 4th. Sarries go through to possibly win the championship??

Extra-time anyone?
HT: Northampton 13-13 Saracens
You might remember that last year's Premiership final between these sides went to extra-time and given we're level here it might be worth a reminder of what would happen if we finish all square.
Firstly, we would have 20 minutes of extra-time, 10 minutes each way. And if the sides still cannot be separated then the team that has scored the most tries will go to Twickenham.
If they're level on tries too then it'll be down to penalty kicks. Surely it won't go that far, will it?

"Saints will be disappointed to only be level after dominating the opening half. But they were left chasing the game when Saracens wing David Strettle hacked on for Duncan Taylor, exploiting a gap behind the defence that was left by the stricken Ahsee Tuala.
"So far, the visitors have shown little in attack - but, they do have Owen Farrell's boot. You feel Sarries must show more after the break though, or the champions seem likely to eventually grind them down."

Northampton try to get moving but to their credit Saracens stand firm. Saints are up to eight, nine phases but they can't get over the 22. That's a dozen phases now. Ken Pisi then gets absolutely smashed by Jacques Burger who is then penalised for not rolling away. Burger reacts angrily and shoves Lee Dickson in the chest, but there is no card and it will just be a penalty with the last kick of the half.
Post update

We're a minute away from the break but Northampton have a penalty just inside their own half for Jacques Burger rolling Luther Burrell by the neck. Stephen Myler kicks deep and the Northampton pack will have one last chance for a catch and drive to the line.

Worryingly for Northampton, James Wilson, who replaced Ahsee Tuala at full-back early on, also appears to be struggling with an injury. Saints might be keen for half-time to come now. They've lost that momentum they had earlier in the half.

This time Owen Farrell makes no mistake as he strokes over his kick from a slight angle 40m out to give Saracens the lead for the third time.

Northampton 0-7 Saracens
What a start for Saracens! With Ahsee Tuala down they take full advantage of their numerical advantage by spinning the ball wide.

England stars Dylan Hartley, Courtney Lawes, Tom Wood and Luther Burrell are among those to return to the side that lost at Welford Road.

Saracens wing Chris Ashton, who scored four tries in the win over Welsh that secured a play-off spot last Saturday, is only fit enough to start on the bench after illness. There's also a late change among the Sarries replacements as Jared Saunders comes in for the ill Schalk Brits.

Sarries beat illness, as well as Saints
FT: Northampton 24-29 Saracens
Saracens director of rugby Mark McCall revealed after his side's semi-final win over Northampton that his team had defied a sickness bug that had swept through the squad.
Prop Shalk Brits wasn't fit enough to make the bench, while wing Chris Ashton recovered to take his place among the replacements.
"We had a mass of sickness around the squad this week. Schalk Brits was in hospital for two days and lost seven or eight kilograms," said McCall.
"There were 10 other people who had it, but you wouldn't have known. Chris Ashton was among the worst and Brad Barritt has been in a mess, but you wouldn't have been able to see that.
"You add the bug to the occasion and it tells you the sort of group we have."
Mallinder takes defeat on the chin
FT: Northampton 24-29 Saracens
Northampton director of rugby Jim Mallinder said:
"We knew what their plan would be and they did what we expected, but they do it very, very well.
"At the breakdown they were physical. Those Vunipola brothers.... once they get over the ball their stomachs are touching the ground already. It's near impossible to move them.
"Everyone decides how they want to play and Saracens have gone down their route. That's the game.
"They do it very, very well. To become champions you have to beat all styles and we didn't get over this hurdle."

But they didn't really have a bench like ours, and we knew that. Once we got that fourth try we settled down and ran away with it a little bit."

Bath fly-half George Ford told BT Sport: "I think in these play-off games, when you get opportunities in the red zone you have to take them. To get seven tries is pleasing, but I'm not sure it'll be like that again next week."

FT: Bath 47-10 Leicester
Bath fly-half George Ford told BT Sport: "It was anything but easy. We had to defend for long periods of time. To be fair, the boys kept putting their bodies on the line and we got a few tries from turnovers at the end there. The score probably doesn't reflect how the game was."

Bath 47-10 Leicester
If you hadn't guessed already, Bath are heading to Twickenham! They will take on Saracens in next Saturday's final at Rugby HQ.
Try (Watson, con Ford)
Bath 47-10 Leicester
And there is the cherry on top of the Blue, Black and White icing on Bath's cake.
Carl Fearns puts in a monster hit on Julian Salvi on halfway and, within the blink of an eye, Anthony Watson streaks clear of the Tigers defence for Bath's seventh try. Just emphatic.
The conversion from George Ford even means the hosts trump the 45 points they stuck on Leicester back in September.
Post update
Bath 40-10 Leicester
Leicester have fought so hard for so long, but have fallen apart a bit here. Anthony Watson and Matt Banahan team up yet again to take Bath forward on the break, but George Ford's kick through drifts out of play and means, for the first time, the home side have entered the Leicester 22 and not scored.

Simon Meredith: We're going to Twickenham! Allez les Blues!
Try (Banahan, con Ford)
Bath 40-10 Leicester
But Bath are just too sharp, too clinical and, dare I say it, too good.
The Blue, Black and Whites break from inside their own 22, Anthony Watson's turn of pace takes them deep inside the Leicester half and Matt Banahan sails over the line for his hat-trick and Bath's sixth try.
George Ford's conversion extends the lead to 30 points. Has this really been a 30-point match?!
Post update
Bath 33-10 Leicester
Full credit to Tigers, still they knock on the Bath door, but still the hosts refuse to let them in. Another JP Doyle blow of the whistle means another Leicester penalty, however, so we're back into touch.
Replacement
Bath 33-10 Leicester
Peter Stringer, playing at The Rec for the final time, is given a wonderful ovation as he's replaced at scrum-half by Chris Cook. Leicester, meanwhile, are up to the Bath five-metre line and win a penalty for their troubles too.
Post update
Bath 33-10 Leicester
For those still keeping count, that is indeed five visits to the Leicester 22 and five Bath tries. Tigers are fighting until the very end here though, as you'd expect them too, as Brad Thorn launches himself into a couple of Blue, Black and White tacklers.

Try (Ford, missed con Ford)
Bath 33-10 Leicester
If they weren't already, Bath are definitely heading to Twickenham now!
So simple, but so effective from Mike Ford's men. Semesa Rokoduguni gets clear down the right, draws the tackle and offloads to George Ford, who runs through from around 15 metres out. The Premiership Player of the Season misses the conversion this time - but the home side are running riot at The Rec.
Post update
Bath 28-10 Leicester
This has just not been Leicester's day. Niki Goneva and then Christian Loamanu both knock the ball on in the same passage of play and Bath have a scrum. A cutting edge is all that's separated these two teams.

"Leicester have only got themselves to blame. They have missed four kicks at goal and they have lived in the Bath half of the field. That is Bath's first excursion into the Tigers half in the second half and that is another try for Bath."
Try (Stringer, con Ford)
Bath 28-10 Leicester
This is quite unbelievable. I make that four visits to the Leicester Tigers 22 - and four tries scored by Bath. After securing good line-out ball, Francois Louw wriggles clear and tees up Peter Stringer, who touches down from close range.
Has the 37-year-old former Ireland scrum-half sent Bath to Twickenham? The two points added by George Ford from the tee would certainly add some weight to that theory.
Post update
Bath 21-10 Leicester
Now Niki Goneva is almost through down the left, but again the home side get back to him! And, as George Ford launches a counter-attack, Mathew Tait gives away a penalty and Bath are able to send the ball up-field. Breathing space for the Blue, Black and Whites.
Post update
Bath 21-10 Leicester
Having opted to boot the ball long via George Ford, Bath are defending once again. The sizeable frame of Christian Loamanu smashes through a couple of tackles to take Tigers into enemy territory, but replacement hooker Rob Webber does superbly to turn the ball over.
Post update
Bath 21-10 Leicester
Bath have made 92 tackles to Leicester's 42, which tells it's own story. Mike Ford's side have entered the visitors' 22 only three times in the opening 57 minutes - but have scored on each occasion.

Leicester are working through the phases now, as this game starts to return to some kind of watchable structure at long last. But Bath have turned it over and look to run it from deep inside their own half.

Sam Burgess's afternoon is over now, as he's withdrawn for Matt Garvey. He's not quite had the same impact here as he has done in recent weeks for Bath, now playing at flanker of course.
Post update
Bath 21-10 Leicester
After the breathless opening period, there's been absolutely no flow to this second half whatsoever. A couple of resets eventually lead to Leicester knocking it on after picking it up at the base of the scrum, meaning a further set-piece.
Replacement
Bath 21-10 Leicester
Huge cheers ring out around The Rec as captain Stuart Hooper is withdrawn. I wonder if he'll be leading his side out at Twickenham in the final next week? Not if Leicester have anything to do with it, as another knock-on means another scrum, which this time Tigers scrum-half Ben Youngs will insert.

Bath 21-10 Leicester
As Bath clear the ball long, Leicester knock on, so we'll have a scrum. Tigers have generally had the better at the set-piece so far this evening - and it's another huge push which allows them to turn it over here too.
Post update
Bath 21-10 Leicester
This second half, with the injury to Niall Morris, just hasn't quite packed the same punch as the first. And that'll suit Bath, who were down to 13 and then 14 men for the first few minutes, and have now won a penalty after Jordan Crane was penalised for holding onto the ball on the floor.
Missed penalty (Bell)
Bath 21-10 Leicester
Tommy Bell takes over kicking duties from Freddie Burns then, but he misses the posts too. That's 12 points - enough to have Leicester in the lead - wasted from the tee now.
Post update
Bath 21-10 Leicester
Winger Matt Banahan, scorer of two of Bath's three tries, has gone in at number eight in place of Leroy Houston, who's still got another minute or so left in the sin-bin. And Leicester win a penalty from the scrum too - surely that wasn't Paul James again?!
Post update
Bath 21-10 Leicester
After a long pause in play, Niall Morris is at last withdrawn to warm applause from around The Rec. Despite this fierce rivalry, it's always good to see opposition fans recognise when a player is seriously hurt. Time for a scrum.
Replacement
Bath 21-10 Leicester
Tommy Bell comes on to replace Niall Morris, who missed a few months earlier this season with an ankle injury. The 26-year-old Irishman is lifted onto a stretcher.
Ouch!
Bath 21-10 Leicester
Now, that looks like a sore one for Niall Morris. He goes tumbling under Ross Batty's tackle, and is now receiving some treatment for an ankle injury. The Leicester man looks in a serious amount of discomfort.
Missed penalty (Burns)
Bath 21-10 Leicester
Freddie Burns can't land the kick though, so that's an early escape for Bath. Anthony Watson is back on the field, by the way, meaning the Blue, Black and Whites are back up to 14 men.
Kick-off
Bath 21-10 Leicester
Here we go then. Bath fly-half George Ford gets us under way - but his kick is not what he was looking for, and then Leicester win a penalty from the resulting scrum. An early chance for Freddie Burns?

Half-time
Bath 21-10 Leicester
A frantic, crazy, breathless 40 minutes of rugby union. But who expected anything different? Bath lead by 11 points at the break.
Try (Tom Youngs, con Burns)
Bath 21-10 Leicester
At last! Following the line-out, Leicester have the rolling maul in fine, working order, allowing Tom Youngs to peal off the side and bundle his way over. Freddie Burns's conversion is good, and Bath's resistance has been broken on the stroke of half-time. That should make Leicester director of rugby Richard Cockerill a little happier.
No try (Morris)
Bath 21-3 Leicester
Niall Morris has indeed dropped it, owing in part to some fine last-ditch defensive work from Semesa Rokoduguni. We'll go back for that advantage, however...

It's three conversions from three from George Ford too and, I know I promised not to mention that 45-0 again, but...
Post update
Bath 14-3 Leicester
Matt Banahan, one of only two Bath players to have featured last time they were in the play-offs in 2010, seems to have the Midas touch this evening. His long kick pegs Leicester back from the restart.
Try (Banahan, con Ford)
Bath 14-3 Leicester
And, like a switch, Bath turn it on in emphatic style once again to stretch their lead. Jonathan Joseph is at the heart of it once more, sending Matt Banahan through out wide to cross in the corner. That is utterly ruthless from Mike Ford's side - whose advantage is extended further by George Ford's conversion.
Post update
Bath 7-3 Leicester
That seems to have sprung Bath back into action however, gathering the restart and immediately pinning Leicester back. Here's Sam Burgess now, taking the ball into contact, making some ground...

Leicester are, at long last, on the scoreboard. It's third time lucky for Freddie Burns, who splits the post from 30 metres or so.

Post update
Bath 7-0 Leicester
Having secured good ball from the set-piece, Mathew Tait is again in the thick of things, releasing Julian Salvi out wide. The back-rower doesn't have the pace to wriggle clear - but he does do enough to win Leicester yet another penalty.

Missed penalty (Burns)
Bath 7-0 Leicester
Freddie Burns, all of 47 metres from the posts, has a go but the ball comes back out off the upright. Niki Goneva is the man to gather it too, but Tigers concede a penalty and it's a real let off for Bath.
Leicester, make no mistake about it, are on top here.

The first one collapses, so referee JP Doyle asks the two packs to have another crack. The experienced Peter Stringer feeds it in for a second time - and Leicester have a penalty this time.

How about that for a start from the Blue, Black and Whites? It's vintage Bath as, following the set-piece, George Ford draws the tackle to release Jonathan Joseph, whose arrowed pass then picks out Matt Banahan on the wing to cross in the corner.
Ford's conversion, from the tightest of angles, is exquisite too and I'd imagine this is just how his father, head coach Mike, would've planned it.

Another fond farewell
Bath v Leicester (17:00 BST)
Following the flurry of fond farewells this time last week, with Sale winger Mark Cueto and London Welsh centre Tom May both bringing their playing careers to an end, we could have another one on our hands today.
At the ripe old age of 40, New Zealand World Cup winner Brad Thorn is in the Leicester Tigers side this afternoon - but is very much hoping to postpone his retirement by another 80 minutes.
"I feel so lucky and blessed but it would be great to push on for one more game and play at Twickenham," he told BBC East Midlands today. "It's a special place to play."
You can read more from Thorn in this rather nicely crafted feature by our very own Owen Phillips.
Are you 'mad for it'?
Bath v Leicester (17:00 BST)
The Blue, Black and Whites need to be "mad for it" when they take on Leicester Tigers this afternoon, according to fly-half George Ford.
Ford is one of eight Bath players to be named in England's 50-man training squad for this year's World Cup - and each one of them will be hoping this won't turn out to be their last competitive action before the tournament kicks off on 18 September.
"These are the games you want to play in as a team and as individuals, and we're just looking forward to it," Ford told BBC Radio Bristol.
"Leicester are going to come here mad for it - and we've just got to be mad for it ourselves."

That 45-0 drubbing - and Tigers fans, I promise I'll try not to mention it again - was just one part of a pretty scratchy start to the season for Richard Cockerill's Leicester.
But don't they always just come roaring back when it really matters?
"I have always said it was about where we sit after round 22 - and we sit third," Cockerill told BBC East Midlands Today. "It doesn't matter where you are halfway through the season and you are sat in seventh or eighth and everybody has already made their mind up that it is a disaster.
"It's the end of the season that counts. We are the form team in the league in 2015, so there is some satisfaction in that."

And, speaking of previous encounters, if you're in Leicester's camp there is one that certainly does stick out like a very sore thumb from the rest.
Back in September, Bath ran out 45-0 winners against Richard Cockerill's side at The Rec, the heaviest top-flight defeat ever inflicted upon Tigers.
"It was not good," Lock Graham Kitchener told BBC East Midlands Today. "I tried to wipe it from my mind.
"For the boys who played in it was a bit of a turning point. We thought we can't go back to that. Everything that could have gone wrong did go wrong that day. It was bit of freak result."
A long-distance derby?
Bath v Leicester (17:00 BST)
Having first faced one another on Saturday, 13 September 1913, the century old rivalry shared between Bath and Leicester Tigers is one of the most famous in domestic rugby union.
A derby in every way apart from location, the two sides have played 26 times in the Premiership, with Tigers having won 16 and Bath only nine.

"Saints have never had the momentum during this game. I don't think Saracens have done anything amazing to win this, but their defence has been absolutely fantastic."
Penalty (Farrell)
Northampton 21-29 Saracens
It's over and surely that's it? Owen Farrell is the coolest man inside Franklin's Gardens as he strikes the ball precisely between the sticks. Those three points extends his lead at the top of the list of points-scorers in Premiership semi-finals.

Could that be that? Billy Vunipola turns the ball over on the Saints 10-metre line and Northampton are penalised. Owen Farrell will have a kick to win this from around 45 metres.

"You can feel the tension in Franklin's Gardens that then erupts into cries of elation at every refereeing decision. Saracens are camped on their own line but so far Saints can't find a way through.
"The champions are clinging on to their title by a thread, with boss Jim Mallinder now using all his replacements. I can taste extra-time."

That's a great take by Jamie Elliott on halfway from Owen Farrell's bomb. But his good work is undone as Gareth Denman knocks on and Saracens will have the put-in at a scrum on halfway.

That's a great kick by Kahn Fotuali'i as the replacement scrum-half plants the ball behind the Saracens defensive line and into touch in the corner, five metres from the visitors' line. You sense Northampton are cranking up the pressure with only 10 minutes to play.

Saracens' defensive work is impressive as they keep Northampton at bay but, the home side stay patient and go through the phases again, keeping the ball tight. But Sarries' resistance is rewarded when Alex Waller is pulled up for not staying on his feet and Owen Farrell clears.

Saracens want to disrupt the Northampton ruck with the boot but time and again they are being pulled up for kicking the ball out of a Saints player's hands.
Stephen Myler kicks for territory, and then does so again after Sarries are penalised again for pulling down the maul, The home side are camped in the Saracens 22.

That's a blow for Northampton. No sooner are they back in the game then Gareth Denman is penalised after losing his footing at the scrum. Owen Farrell will kick for goal.
Try (Wood)
Northampton 21-23 Saracens
Northampton go for the catch and drive but it all seems to be going wrong until Jamie Elliott and Kahn Fotuali'i join in to regain the momentum. It works as Tom Wood goes over and touches down, only for Stephen Myler to slice his conversion attempt wide. That's his 100% record with the boot gone for the afternoon and how costly could that be?

Northampton 16-23 Saracens
Credit to Northampton, though, they will not give this up. They spin the ball wide to George Pisi who is stopped in his track illegally by Owen Farrell. Stephen Myler goes for the corner.

"Saracens are putting Saints under huge amounts of pressure and what they're doing is either turning the ball over or winning penalties. Their kicking has been very, very accurate. I'm very impressed.

Saracens lead by seven points as Owen Farrell makes it four kicks from five as he lands from the tee once more.
Post update
Northampton 16-20 Saracens
Saracens' energy levels appear to be higher than Northampton's at the start of this half. With a stronger-looking bench is this their chance to take control. They have a penalty coming too midway inside the Saints half after Tom Stephenson is penalised for not rolling away.
Replacement

Try (George, con Farrell)
Northampton 16-20 Saracens
George Kruis takes the ball at the back of the line-out and the Saracens pack power forward, driving hooker Jamie George over the line. Owen Farrell adds a tricky conversion from near the touchline. Northampton led for only three minutes but they're behind again now.
Post update
Northampton 16-13 Saracens
Once again, a penalty is followed by another penalty as Saints are penalised on their own 22. It's on the touchline so rather than go for the posts, Owen Farrell kicks for the corner. It's Saracens' turn to try their luck from a set-piece.
Penalty (Myler)
Northampton 16-13 Saracens
Stephen Myler makes no mistake from 15 metres out and almost right in front of the posts to maintain his 100% record. Northampton are in front for the first time.

Extra-time anyone?
HT: Northampton 13-13 Saracens
You might remember that last year's Premiership final between these sides went to extra-time and given we're level here it might be worth a reminder of what would happen if we finish all square.
Firstly, we would have 20 minutes of extra-time, 10 minutes each way. And if the sides still cannot be separated then the team that has scored the most tries will go to Twickenham.
If they're level on tries too then it'll be down to penalty kicks. Surely it won't go that far, will it?

"Saints will be disappointed to only be level after dominating the opening half. But they were left chasing the game when Saracens wing David Strettle hacked on for Duncan Taylor, exploiting a gap behind the defence that was left by the stricken Ahsee Tuala.
"So far, the visitors have shown little in attack - but, they do have Owen Farrell's boot. You feel Sarries must show more after the break though, or the champions seem likely to eventually grind them down."

HT: Northampton 13-13 Saracens
So, here's the tale of the tape at the break.
Half-time
Northampton 13-13 Saracens
That is indeed the last kick of the half and both sides troop off to the dressing rooms. This is too close to call.
Penalty (Myler)
Northampton 13-13 Saracens
The kick is right in front of the posts, 20 metres out, and Stephen Myler slots it over with the minimum of fuss. We're all level going into half-time.
Post update
Northampton 10-13 Saracens
Northampton try to get moving but to their credit Saracens stand firm. Saints are up to eight, nine phases but they can't get over the 22. That's a dozen phases now. Ken Pisi then gets absolutely smashed by Jacques Burger who is then penalised for not rolling away. Burger reacts angrily and shoves Lee Dickson in the chest, but there is no card and it will just be a penalty with the last kick of the half.
Post update
Northampton 10-13 Saracens
We're a minute away from the break but Northampton have a penalty just inside their own half for Jacques Burger rolling Luther Burrell by the neck. Stephen Myler kicks deep and the Northampton pack will have one last chance for a catch and drive to the line.
Post update
Northampton 10-13 Saracens
Worryingly for Northampton, James Wilson, who replaced Ahsee Tuala at full-back early on, also appears to be struggling with an injury. Saints might be keen for half-time to come now. They've lost that momentum they had earlier in the half.
Penalty (Farrell)
Northampton 10-13 Saracens
This time Owen Farrell makes no mistake as he strokes over his kick from a slight angle 40m out to give Saracens the lead for the third time.
No sooner has that kick gone over then Alex Waller, who scored the try that won the title for Saints last season, replaces Alex Corbisiero at prop.
Post update
Northampton 10-10 Saracens
But it's not long before Saracens are awarded a third penalty in quick succession midway inside the Northampton half after Saints are penalised for not rolling away.
Missed penalty (Farrell)
Northampton 10-10 Saracens
This one's more difficult for Owen Farrell and this time he pulls his angled kick across the face of the posts and wide.
Post update
Northampton 10-10 Saracens
That's now three penalties in only a matter of moments as new England squad call-up Maro Itoje draws the penalty for Saracens, prompting Owen Farrell to call for the tee once again.
Penalty (Myler)
Northampton 10-10 Saracens
And it's no surprise that Stephen Myler makes no mistake with the boot from right in front of the posts. We're all square once again.
Post update
Northampton 7-10 Saracens
But how often do you see one side score a penalty and then concede one? That's what Saracens do here as Petrus Du Plessis tackles George Pisi off the ball. Stephen Myler has a chance to tie the scores once again.

Saracens are back up to full strength as Mako Vunipola returns to the fray. The visitors will be happy to have only conceded one score in that 10 minutes.

That was an impressive response from Northampton after that early setback, and their forwards show signs of taking control as they drive the Saracens scrum backwards to be rewarded with another penalty which puts them deep in opposing territory once more.

"Both sides started cagily, happy to either kick deep or test with high bombs. Nerves have been cast aside in the stands though, as the home crowd dragged Saints to parity inside an electric Franklin's Gardens. A crucial spell coming up with Saracens prop Mako Vunipola in the sin bin."
Try (Penalty, con Myler)
Northampton 7-7 Saracens
That Northampton pressure pays off as Owen Farrell is ruled to have stopped Saints' catch and drive illegally and referee Greg Garner goes under the posts to award a penalty try. Stephen Myler slots over the simplest of conversions and we are level.
Sin-bin (M Vunipola)
Northampton 0-7 Saracens
Once again Saracens can only stop Northampton illegally and referee Greg Garner sends Sarries prop Mako Vunipola to the bin. The visitors are under all sorts of pressure.
Post update
Northampton 0-7 Saracens
Dylan Hartley's line-out is secured and Northampton rumble towards the line. They think they are over but the referee says no and instead gives Saints a penalty for Billy Vunipola going in at the side. Saints will try again.

That's a good crossfield kick by Northampton centre Luther Burrell, who saw David Strettle out of position and knocked it behind him. Alex Goode gathers but can only run it into touch for a Saints line-out midway inside the Sarries half.

"What a start that is for Saracens. A brilliant kick from David Strettle that just held up, a fantastic chase down the line and they were over in the corner. Just how important was it that full-back Ahsee Tuala was out of position for Northampton?"
Try (Strettle, con Farrell)
Northampton 0-7 Saracens
What a start for Saracens! With Ahsee Tuala down they take full advantage of their numerical advantage by spinning the ball wide. David Strettle boots it downfield from inside his own half and Duncan Taylor wins the foot race to give it back to his supporting wing, who dives over from a couple of metres out. Owen Farrell slots over the conversion from the touchline.
Post update
Northampton 0-0 Saracens
Saracens wing Chris Wyles shows no nerves as he takes a high bomb from Lee Dickson on his own 22. That was a positive first touch. Worryingly for Saints full-back Ahsee Tuala is having treatment on halfway.
Kick-off
Northampton 0-0 Saracens
Referee Greg Garner blows his whistle, Northampton fly-half Stephen Myler kicks high and long and we are off.

Saints to use play-off experience
Northampton v Saracens (14:00 BST)
Northampton have plenty of experience of the play-offs, having reached two successive finals and beating Saracens to win their first Premiership title 12 months ago.
And flanker Tom Wood says they must use that to their advantage to book another trip to HQ this afternoon.
"We've been there and won it and I know what it feels like and I just want to repeat it," he told BBC Radio Northampton.
"We've got to make sure we show the same level of hunger that we did in the final and semi-final last year."
Sarries will relish atmosphere
Northampton v Saracens (14:00 BST)
Northampton won both league meetings between the sides this season, winning 31-24 in November at Allianz Park and 25-20 in April at StadiumMK.
But Saracens director of rugby Mark McCall said his side would not be intimidated by the inevitable white-hot atmosphere inside Franklin's Gardens this afternoon.
"We have got a squad who don't mind being on the road and kind of relish hostile atmospheres," he told BBC London 94.9.
"The atmosphere we faced when we played Clermont in the Champions Cup was something very special.
"Having been through that and played quite a decent game that day, I don't think anywhere else will have big fear for us."

Northampton v Saracens (14:00 BST)
So, it's Bath v Leicester at 17:00 BST but with all the stellar names in those Northampton and Saracens line-ups, the appetiser to that game isn't too shabby either.
It's only a repeat of last year's final, which Saints won in the most dramatic of fashions thanks to Alex Waller's try in the last minute of extra-time.
Team news
Northampton v Saracens (14:00 BST)
After resting their star names for the trip to Leicester last week in their final league game of the season, Northampton revert back to the same 23-man squad that beat London Welsh a fortnight ago.
England stars Dylan Hartley, Courtney Lawes, Tom Wood and Luther Burrell are among those to return to the side that lost at Welford Road.
Saracens wing Chris Ashton, who scored four tries in the win over Welsh that secured a play-off spot last Saturday, is only fit enough to start on the bench after illness. There's also a late change among the Sarries replacements as Jared Saunders comes in for the ill Schalk Brits.
But there are starts for England centre Brad Barritt and scrum-half Richard Wigglesworth, as well as 20-year-old forward Maro Itoje, who was named in Stuart Lancaster's 50-man World Cup training squad this week.
Team news
Northampton v Saracens (14:00 BST)
Northampton: Tuala; K Pisi, G Pisi, Burrell, Elliott; Myler, Dickson; Corbisiero, Hartley, Ma'afu, Lawes, Day, Wood, Clark, Manoa.
Replacements: Haywood, Waller, Denman, Dickinson, Fisher, Fotuali'i, Stephenson, Wilson.
Saracens: Goode; Wyles, Taylor, Barritt, Strettle; Farrell, Wigglesworth; M Vunipola, George, Du Plessis, Kruis, Hargreaves, Itoje, Burger, B Vunipola.
Replacements: Saunders, Barrington, Figallo, Hamilton, Wray, De Kock, Hodgson, Ashton.

Post update
Bath v Leicester (17:00 BST)
Later we have a match-up for you steeped in tradition.
Bath against Leicester is one of the oldest rivalries in English rugby, with the two clubs having gone at it hammer and tongs against each other for more than 100 years.
It's one that in more recent times evokes memories of Guscott, Chilcott and Barnes in the Blue, Black and White, and Kardooni, Johnson and Rowntree for Tigers.
Not to mention England fly-half George Ford, who has played for both clubs and will be hoping to lead Bath into the final today. But more of that later.
How they finished
Here's how the Premiership table ended up after last weekend's final matches.
It was quite a Saturday afternoon as Leicester, Saracens and Exeter battled it out for the two remaining places to join Northampton and Bath in the play-offs.
Leicester's win over a weakened Saints guaranteed their progress, while Sarries edged out the Chiefs on points difference thanks to a big win over London Welsh.
