Bath have a scrum from a Saints knock-on and this really is the last chance saloon.
They need something special.

Chants of "Who are ya?" from the Saints fans - they're inching closer to a first title in a decade.
They've had to wait for their chance in this second half but a magnificent run by George Hendy, finished off by Alex Mitchell, has put them on the brink of victory.
Time is running out for Bath.

Line-out lost!
Bath have it.
Northampton 25-21 Bath
Bath are back on the attack and into Saints' half.
Cam Redpath tries a miracle offload and it goes out of play.
That wasn't the play as Lawrence had stepped inside.
Saints have the ball, if they keep it they will be the Premiership champions.

Something out of nothing and you've got to give great credit there to George Furbank who didn't panic.
George Hendy showing his class and there we were saying that Alex Mitchell has not had his best game - he was there when we needed him.

A brilliant Northampton try that maybe wins the title for Saints.
Putting things right after his quick tap, Mitchell goes over the line!
Alex Mitchell; con Furbank
Alex Mitchell is the scorer but this try is all about George Hendy!
What a run from the sub who surges through a gap and through tacklers before offloading to the England scrum-half who wrongfoots Joe Cokanasiga to go over the line.
The conversion from George Furbank goes over and Saints have a four-point lead with five minutes remaining.
What a game this has been - have we got one final twist?

Bath have got to be careful and not give Northampton territory or possession.

In another blow to Saints, they have lost fly-half Fin Smith to injury.
Tom James is on and it means a reshuffle which sees George Furbank move to 10.
Northampton 18-21 Bath
Bath win the penalty at the scrum and can clear.
Saints prop Emmanuel Iyogun the guilty party according to ref Christophe Ridley.

I can't believe what Alex Mitchell has just done, they're just not thinking straight.
How have they not gone for goal and levelled this game up.

It's turning out to be a bit of a nightmare this second half for Northampton Saints.
It's all the Bath supporters who are singing now.
Saints have treated us to some stunning comebacks this season and they need another one.
Northampton 18-21 Bath
Saints penalty... but scrum-half Alex Mitchell takes a quick tap instead of going for the posts.
Risky move and it doesn't work as Bath win the turnover.
How important could that be?
This has been an almighty defensive performance from Bath.

There's a huge roar from the Bath fans as Finn Russell's penalty sails between the posts to give them the lead for the first time since they led 3-0 early on - how long ago that feels now!
This has been an amazing performance from the 14 players in blue, black and white.
Their defence has been the best in the league in second halves of games this season - can they keep Saints out from here and win the title?

Bath have got this spot on and have executed things brilliantly.
This game is swinging and it's swinging in Bath's favour.
You can feel it in the air and it's absolutely brilliant.
Finn Russell
Bath lead!
Finn Russell makes no mistake and Bath are in front in the Premiership final with 13 minutes remaining.
Saints need to respond against the 14-men who have been heroic to this point.
They've fought back from 15-3 down.
Northampton 18-18 Bath
Bath penalty!
And it's very kickable.
A quick, very quick chat results in Finn Russell opting for the posts and to give his side the lead.
