Relive women’s semi-finals day

1. Williams beats Sharapova 6-2 6-4 in women's semis
2. Muguruza beats Radwanska 6-2 3-6 6-3 in other semi
3. Jamie Murray reaches men's doubles final

The women's final line-up has been decided. The familiar - Serena Williams - versus the new kid - Garbine Muguruza. But what about the men's? A superb semi-final Friday will decide that for us. Novak Djokovic? Richard Gasquet? Andy Murray? Roger Federer? Two into four just won't go.

Thanks, as always, for joining us. Wimbledon 2Day will sate your tennis appetite at 20:00 BST but, for now, it's goodbye from us. Until tomorrow.

McEnroe for Maria?

John McEnroe

Three-time Wimbledon champion on BBC TV

A caller asks if John McEnroe would ever coach Maria Sharapova, to help her improve her serve....

"I don't think it would work. In fact I'm fairly confident that won't happen."

That's that, then.

Great result for us - Murray

"It's a great result for us. We got off to a bit of a slow start but I think we were helped out with Erlich's injury because he was struggling with his knee," says Jamie Murray.

"John played a lot of great shots. This is our third year together so for a doubles team that's quite a long time. We've stuck through it and getting our reward. We're excited to be here."

Murray & Peers into final

"That was a fabulous performance. It wasn't easy, they lost the first set but got right back into it in the second set. Peers served so well and Murray backed him up with the volleys and crossing at the right time. A superb partnership."

Murray & Peers into final

A healthy crowd on Centre Court and they're applauding in ovation. The camera finds Judy Murray, hiding a salty tear behind her shades perhaps. David Beckham stands to applaud the winning pair off the court. One Murray into the final. Over to you, little bro.

Game, set and match

Murray opens with an ace. Confident. 15-0. Erlich with a forehand that bounces wide of hte tramlines. 30-0. Petzchner's return goes long. 40-0. Peers with the winning volley. Victory!

Erlich struggling, that right knee clearly bothering him, but it doesn't affect him on his serve, blocking out the pain to hold to love. Murray with a chance to serve for the match.

Murray and Peers have never before been in a doubles Grand Slam final. Erlich and Petzschner blooting their groundstrokes. Murray and Peers forming a wall at the net and the final is within touching distance.

Semi-final predictions

Tim Henman

Former British number one on 6-0-6 on BBC Radio 5 Live

"Andy Murray has to be aggressive. Roger Federer doesn't beat himself, he is so offensive, Andy needs to be proactive enough to get Federer on the back foot. A lot will be dictated by the serving. The person who has a good serving day will create the opportunities."

Peers treating the Petzschner second serve as if it's free lunch. Fine play from Murray at the net, too. The pair gather three break points. This match could soon be over. Double fault and Murray can smell the final.

What has Tim Henman to say about Friday's semi-final against Roger Federer and Andy Murray I hear you say?

Roddick on retirement

Andy Roddick

Former world number one on BBC Radio 5 Live

"I don't think there is a plan for most players. The majority have to go and find a job. Some go back to school, a lot of them network or coach.

"I didn't have a plan. I went to bed thinking I was going to play in the US Open, but I woke up and I didn't want to play anymore. I didn't have time to make a real plan. I don't regret my retirement."

Murray to serve, break in the bag. A tickle of the fingers between Murray and Peers as they ease 40-15 ahead and the Scot comfortably serves out.

Promising for Murray and Peers, claiming the first point, but it's the only sniff they get on Erlich's serve. A hold to 15 for the man with bandage around his knee.

Peers with the balls and he's usually solid. A slam-dunk smash from Murray secures a hold to 15. Break consolidated, crowd stirring.

Murray or Federer? Semi-final predictions

Andy Roddick

Jamie Murray and Peers are a set away from Saturday's final. Either one of the next two will do fine. Preferably the first one.

Murray/Peers save three break points

Philipp Petzschner absolutely marmalises a return to 0-30, before John Peers ducks out of the way as the ball blazes a trail for his eyebrows and looks back to see it drop inside the baseline.

0-40 and three break-back points.

Murray and Peers clamber their way back to deuce. Phew, but still work to do.

Murray/Peers break

Well, it's easy when you play it like that.

An absolute cannon of a two-handed backhand from John Peers gets he and Murray to deuce.

Jamie Murray flings himself across the net to flick away a volley for break point.

And Philipp Petzschner cuffs Peers' return long as he attempts to come in to the net.

Peers to serve for the set next.

Jamie Murray's service wobbles have steadied.

He holds for the loss of just one point.

This set could be the pivot point of the match. Both teams are guarding serve jealously knowing that a dropped serve now could be fatal.

We have had new balls, but now we have rolled out a fresh set of line judges while the old ones head off to sharpen their eyeballs and tighten their vocal cords.

John Peers, service cyborg, rains down another hold to love. The Australian is not the tallest, but has a skiddy, flat delivery that is difficult for the man opposite to pick out.

ALLSPORT

Time to plot a better plan.

Jonathan Erlich and Philipp Petzschner are in a bit of danger at 30-30, but their serve survives unscathed.

Jamie Murray strolls to 40-0 but is just a little too clever with a little cross-court volley - it tip-toes along the highwire and drops his side.

It is a mistake that he is almost to regret as he gets bogged down in deuce for a while. But Murray and Peers find their way through.

PA

This was the scene on Henman Hill an hour or so ago. I can't guarantee that it is similarly swimming with people right now, but there are still a fair few sticking around to soak up some late evening rays and the All England vibes.

The tennis is quite relaxing at the moment. A steady stream of service holds.

Another solid service hold. A bit of a nothing game that one, forced errors all round, but not by brilliance.

The first game of the third set goes the way of the German-Israeli duo, but Jonathan Erlich, who got the trainer on to add even more strapping to that dodgy knee at the end of the second set, is struggling.

He is looking very tentative on that joint. A few snake-in-the-grass low ones over the net might test it to destruction.

Good hands

Game and second set

Job's a good 'un.

John Peers, the man that you would want serving for the set, does the bizzo.

We are level pegging.

Brilliant cat-like reflexes from Jonathan Erlich as he bops away a volley on his way to a love service hold.

Actually if cats had reflexes as sharp as that they would spent less time in traffic accidents and more successfully swiping goldfish out of ponds.

Jamie Murray looks like he is heading for a stress-free day at the service office, rattling through to 40-0. But a double fault, a decent mid-court smash from Petzschner and a wafty air-shot attempt to volley from John Peers take us through to deuce.

Steady. Steady.

Murray puffs his cheeks and rediscovers his serving groove to see his team through.

And another hold to love. This time it is Philipp Petzschner who brings the service noise.

Two service winners and an ace. It is not just Serena Williams who can hammer down the bombs on Centre Court today. John Peers is doing a fine job every time the balls are thrown to him.

Jamie Murray is wearing his hat at a jaunty angle. He looks like he is channelling Marky Mark. I don't think that it can be helping him.

ROBERT TIMBRE: Team mates in doubles tapping one another after every point is utterly preposterous. Is it insecurity, a need for reassurance?

Just a bit of bromance team-building Robert, don't worry.

John Lloyd

Former British number one on BBC Two

"Jamie is struggling on the forehand routine but he normally gets into a rhythm with it. That is the side he can sometimes not return too well on. He also has to start getting some rhythm on his serve because he is struggling with it."

John Peers service action is all snap and whip. Compact and powerful like a Tyson hook.

He holds to love, but Philipp Petschner will serve for the set next.

Jonathan Erlich's right knee is strapped so heavily, I'm starting to wonder that if you peeled off the bandages, Invisible Man style, if there would be a joint underneath at all.

If he is playing with no lower leg joint, he is doing remarkably well. Another solid service hold.

Erlich/Petzschner break

Jamie Murray's serve is the weak link out there at the moment, sitting up pretty for Jonathan Erlich and Philipp Petzschner to hammer on return.

The German-Israeli duo are getting stuck in and bring up 0-40 and three break points. And the second is converted via a delicious lob from Petzschner that cascades over the head of Murray and Peers for a sublime winner.

Still on serve. A bit of a phoney war this with the two teams just feeling each other out.

The only real chance for either has been when Jamie Murray slipped to 0-40 in his first service game. It is his turn to deliver the fuzz in the next game...

John Lloyd

Former British number one on BBC Two

"Jamie Murray has played himself into the Davis Cup team against France but who partners him? Andy Murray or Dom Inglot?

John Peers' serve is the more solid and secure of the two tee-offs at the Scottish/Australian end.

I wonder if there is much Ashes chat among them during their time away from the court. And if so, who Jamie is backing?

John Lloyd

"Pretty impressive start from Erlich and Petzschner."

Come on England woman, think like a team like you did in Canada.

Philipp Petzschner holds serve back on the court itself.

Jamie Murray's serve comes under a bit of pressure. Scrap that, a lot of pressure. Love-forty and ugly.

But the Scot and Aussie partner-in-crime John Peers come roaring back to cling onto serve. Break averted.

More for Jonas Bjorkman: "The group have done a great job with Andy, he is looking really strong and had a great season so far.

"Andy and Roger know each other very well, there will not be too many secrets. We have been going through a lot of past matches, through videos, and hopefully we can pull out a few good tactical moves.

"Amelie is very relaxed and easy going and I am the same. We are both here and trying to help Andy so he can achieve his goals in his career. When it is match day, it is him performing.

"It is a lot easier to be on court than off court. It is more nerve wracking because you can't do anything. I am not calm in the box. Amelie has to be a calmer with the baby coming. The crowd is always fair but hopefully in favour of Andy."

Andy Murray's coach Jonas Bjorkman on BBC One:

"It is a lot of fun and a great challenge, I have been here as a player, with the media for a lot of years and now a different view being a coach.

"I have seen different aspects with the pressure but Andy is dealing with it well and he has played some great tennis.

"Hopefully I have a positive impact like the rest of the team. It is a great energy in the group, a lot of laughs, a lot of chit chats."

Jonathan Erlich returns fire for the Israeli/German duo.

"Sharapova is a realist and knows this is a bad match up for her. In the grand slams she manages to go deep, Serena has normally gone out early."

Williams wary of Muguruza

Serena Williams' opponent in the final is Garbine Muguruza and the world number one predicts a "great final".

"It's great for her," said Williams of Muguruza's progress at Wimbledon. "She's beaten me before and she made me improve. It will be a great final.

"The feeling gets better every time I'm here. It's been a long time since my last final. It's really cool."

Sharapova holds

Sharapova double faults at a critical stage, and that's the story of the match. Match point Williams, the Russian on life support. The world number one not at her most ruthless and Sharapova is off the hook after a series of Williams errors. Oxygen oozing through Sharapova's veins once more.

Deuce. Advantage. Deuce. Wild forehand Williams. Advantage Sharapova. Williams into the tape and Sharapova holds.

Sharapova needing to hold to stay in the match. Sharapova has illuminated with the occasional brilliance, swinging from the hip on the baseline and all Williams can do is watch a forehand fly by her ears.

"Sharapova never stops competing, even when it looks oh so bleak."

Dreamy returning from Williams wins her a third break point, but from the sublime to the silly as the world number one balloons a return into the tramlines. A dip from Williams, opting for power rather than precision and Sharapova lives on. For now.

"Serena is applying so much on Sharapova, hitting the second serve from inside the court.

She only hit one first serve in the last game and you can't afford to do that against Serena."

1999 Wimbledon champion on BBC TV

"We've spoken about Serena's serve being the best weapon in tennis. What about her athleticism as well?"

Sharapova a renowned street fighter. The Russian will brawl and scrap until she is forced off the court. Unfortunately for the former champion, at the other end of the court is a woman with an equally fierce will to win. Williams turning the screw and Sharapova's hopes fading in this set.

Previous Grand Slam meetings

It has been 11 years since Maria Sharapova beat Serena Williams. Can she fight back today?

Sharapova broken

Decibels rising on Centre. The shrieks? On a par with a police siren. The applause? The sort you hear at a chess match.

Sharapova lost in a cul de sac, needing to survive two break points, but the ball sits up nicely for Williams in the middle of the court and the American could park a JCB in the space she has to plant her trademark volcanic forehand.

David Beckham adjusts his tie before Williams launches her first missile towards her rival. No excuses for shabbiness in the Royal Box.

The Williams serve not as dominant as you'd expect, which is why Sharapova is allowed to level at 30-30, but a 120mph ace blows Sharapova off the concourse, and the top seed rattles off another boomer.

John McEnroe

Three-time Wimbledon champion on BBC TV

"Sharapova doesn't have the athletic skills but boy does she dig deep. She's often one of the best competitors you'll see. She had to do that to get out of the last game, to keep this set competitive."

Another break point comes Williams' way and yet again she generously gives Sharapova a reprieve, shanking a backhand wide. Sharapova to the net, a change of tactic, and a feather-soft touch has Williams stranded.

The Russian's serve solidifying, Williams' eyes widening as a second serve comes her way - but her return dribbles to the tape.

Sharapova taken to deuce

Sharapova up against it again. The Russian's serve currently as malicious as a hummingbird, hovering at around 103-106mph. Williams bullying her opponent, pinning her on her heels with ferocious forehands and the world number one has gathered a break point.

Canny from Sharapova, a serve to the wings which has the approval of Centre Court. To deuce we go.

John McEnroe

Three-time Wimbledon champion on BBC TV

"Does Maria have a plan B? That's the issue. If plan A isn't working, is she able to turn to different tactics?

Brutal hitting from Williams, and rapid serving too - a 120mph cannon fires her to 40-30. But, just like Sharapova in the previous game, the favourite guilty of sloppy serving - a double fault before she makes amends with an ace. The game finishes when Sharapova fires a faulty forehand into the tape.

Sharapova in choppy waters. One double fault, then another. Murmurs of surprise rippling around Centre. The Russian surrendering with a whimper.

Sharapova taken to deuce

Sharapova looking down to the other side of the net and seeing a formidable force, a woman she has not beaten in 11 years, someone who has collected 20 Grand Slam titles and won 26 Grand Slam matches in succession. Understandable that the Russian is experiencing a knee-knocking start. Williams bludgeons to 30-30 and then forces the Russian to deuce.

When is a rivalry a rivalry? Williams dominant in every category against Sharapova, except of course off-court earnings. The top seed far from living on the breadline, though.

"We're looking forward to watching Serena now. I've been trying to get a ticket for the last few years. I'm buzzing."

Has Sharapova got any chance?

Marion Bartoli

2013 Wimbledon champion on BBC Radio 5 Live

"There is not too much interaction (in the locker room between the players). They do whatever they have to do and there is no connection, which is normal. They are playing for history.

"Maria has been beaten by Serena badly in the past and it is tough to take. If she plays neutral against Serena then Maria has no chance.

"She has to play even more aggressively and hope it is a day when everything goes in, and then maybe she can beat Serena."

Marion Bartoli

2013 Wimbledon champion on BBC Radio 5 Live

"The match-up against Serena is just not working for Maria. Serena takes the ball early, plays attacking tennis, returns from well inside the court and doesn't allow Maria to settle in.

"Maria feels rushed when playing Serena. It's also a mental rivalry, an ego rivalry between two champions when they battle. But game wise there is no rivalry."

Love to hate

There's no doubting Serena Williams adores playing Maria Sharapova. Nineteen meetings have resulted in 17 Williams victories. And, yes, it's true, Sharapova has not beaten the world number one since 2004 when the then 17-year-old Russian beat the American in the Wimbledon final. Williams has not forgotten about that one.

“I love playing Maria. I think she brings out the best in me. I think I bring out the best in her. I thought we had a wonderful final in Australia. It was very entertaining, she played really well.”

Rigor mortis has set in for Mike after nearly five hours in the live text driving seat so it's me, Aimee, taking over for a bit. A toasty Centre Court almost empty, but it won't stay like that for too much longer.

I reckon that Garbine Muguruza is set to join the ranks of Wimbledon crowd favourites before too long.

She seems like a thoroughly lovely person and has the sort of power game that should carry her to the latter stages on a pretty regular basis.

"A star is born today in women's tennis. That lob from Radwanska must have felt it was hanging in the air for so long, and then Muguruza just finished it off."

Game, set and match

Garbine Muguruza drops to the floor in delight as she hammers away a drive volley, checks, just to be sure that the line judges are silent, and then starts her celebrations.

Agnieszka Radwanska will look back on a call she made on the previous point, calling for a review of a backhand from Muguruza that was just in.

Muguruza, not knowing that her opponent had summoned the video gods, was just about to cuff a simple backhand clearly long on the next shot.

Break point saved

Muguruza toughs it out, hitting out bravely to take us to deuce.

Suffocatingly tight.

Break point Radwanska

A nervy backhand about 10 feet long from Muguruza. 0-15.

Oh-er. The pressure up another notch. But she knuckles down, overcomes a call for a foot-fault, and wins the next two points.

Radwanska is not letting this drop though. Back she bites for 30-30.

And then an impeccable volley deep and she has break point...

Radwanska holds

Getty Images

Agnieszka Radwanska survives and you get the feeling that Muguruza might have found it easier to break for her place in the final than to serve out for it.

Anyway, we are about to find out...

Radwanska taken to deuce

Nip, tuck, dodge, dive, softly, softly, catchy, monkey.

A thrilling rally full of bluff and counter bluff ends with Garbine Muguruza unable to retrieve a lob and 40-0 down.

The Spaniard batters back though and a Radwanska error sends us to deuce. Muguruza within two points of victory.

PA

Sweets? In a bucket? What larks!

More importantly, let's see if Garbine Muguruza has a soft centre.

That was as tough as week-old toffee from the Spaniard. A very impressive service game as she soaked up a 24-carat winner from Radwanska that she could do nothing about and then slapped away a knee-knocker of a smash to snuff out the danger.

Mark Woodforde

Former Grand Slam doubles champion on BBC Radio 5 live

"The reset button set has been set for Muguruza. I think if she can continue hitting the corners behind that first serve then we might see her in the final."

Tracy Austin

Two-time US Open champion on BBC TV

"There's two contrasting styles. Muguruza has all out aggression from both wings. Radwanska is looking to put more pace on the forehand side and mixes it up with the bankhand slice, and tries to get the job done with accuracy and defence."

Muguruza breaks

Getty Images

Never mind the rest of the game (some shoddy serving from Radwanska and walloped groundstrokes from Muguruza) just revel in the quality of the final point.

Muguruza walloping, Radwanska retriving, Radwanska into the net, Muguruza with a dead-eyed lob and Radwanska cannot claw it back into play.

Enthralling stuff and Muguruza is two holds away from the final.

Garbine Muguruza flirts with break point danger as her backhand volley at 15-30 down barges through the net cord and makes it over.

Stephen Fry gets another stamp on his 2015 Royal Box loyalty card as he returns for another look down from the prime position.

Martina Navratilova - who had a short and unsuccessful stint as Radwanska's coach earlier this year - is alongside him.

And her former charge is doing some great things down there. Her chopping slice backhands have slowly replaced winners with errors on the Muguruza forehand wing.

A delicious cross-court drop shot seals the game and Muguruza would have had to be stood where the ball boys crouch to get that one back.

Mark Woodforde

Former Grand Slam doubles champion on BBC Radio 5 live

"Certainly a very tense opening few games of this third set. The crowd is knowledgeable and they have seen such matches before and want to see more.

"Muguruza has had these opening but has been hesitant to hit the ball out of the air and finish the points quicker."

Reuters

You could have driven a juggernaut through the slice of court that Garbine Muguruza has to aim at 30-15, but the Spaniard pumps a forehand long needlessly.

You can almost hear the nerves creaking. Back to good Garbine rather than her evil nervy twin though as he picks out a lovely cross-court angle to win the next point and old faithful - the serve - seals the game.

Muguruza breaks

Well, this is turning into a real riddle.

Garbine Muguruza slams the brakes on Agnieszka Radwanska's charge, finding a couple of zippy winners to take the Pole to 0-40 and then luring her into the net on the second of three break points.

That is now six games in a row for Agnieszka Radwanska and suddenly all my previous wittering about Muguruza laying down "a statement of intent for the women's game" looks a little giddy.

She really was playing red-line tennis, but now it looks like she crammed all her best bits into too short a period of the match.

"Radwanska is getting a little bit more confident although I don't think she is doing anything differently. Muguruza just got a little tentative there, making a couple of errors. She has retreated a little, stepping off the return and that has allowed Radwanska back into the match."

Radwanska breaks

Agnieszka Radwanska runs the legs out of Garbine Muguruza and plants the smash into the cheap seats on the bounce.

Let's see what Garbine Muguruza has got when it comes to the pointy end of things then.

"There's no doubt that Muguruza was tight in the last two-and-half-games. She was looking to the final but now it's three games on the trot for Radwanska. There are such small margins at this level."

Garbine Muguruza with two blockbuster forehands, the first a vicious cross-court dipper, the second a curving down-the-line bit of precision take her to 15-30.

But Radwanska is battling and there are a few more errors creeping into the Muguruza game. A couple of stray groundstroke float long as she lets Radwanska off the hook.

"That's a tough break for Radwanska. When I saw the match-up I thought Radwanska would cause problems for Muguruza but she hasn't had the chance.

"Muguruza is playing superbly, hitting the ball with a lot of power, depth, and with that kind of power Radwanska has been unable to throw in that slice that she is known for. Muguruza started strong in the first set and has started strong in the second as well."

Agnieszka Radwanska has a glimmer at 0-30, but this is a dark, dark place she has found herself in.

Garbine Muguruza's serve is thumping like a sub-woofer and the Pole flails out wide to try and retrieve a couple of whoppers.

Mark Woodforde

Former Grand Slam doubles champion on BBC Radio 5 live

"That's the beauty of our sport that you can let a set slide by. Even if Radwanska loses this set 6-2 she still has the opportunity to change her game. She is a thinking player, manipulates the speed of the shot, the angles. Don't discount Radwanska out of this match."

Radwanska holds

Agnieszka Radwanska better start whispering the history of the Centre Court stage and tales of some of the great players who have trod its turf to her opponent during the changeover.

The only thing Garbine Muguruza has to fear is fear itself. She has the momentum of a steam train and serves for the set next.

Radwanska recovers to deuce

A volley into the net from Muguruza and a hammered forehand smash from Radwanska and the inevitable is delayed, but probably not averted.

Two set points Muguruza

The Spaniard has battered her way to within a point of the opener inside half an hour.

With all due respect to British number two Jo Konta, it is hard to believe that she defeated Garbine Muguruza at Eastbourne just a few weeks ago.

The Spaniard is pulling apart Agnieszka Radwanska, whose defensive scampering is some of the best in the game. A hold to 15 as she overpower the Pole once more.

Radwanska needs to find a way to break up her rhythm. And fast.

.

Mark Woodforde

Former Grand Slam doubles champion on BBC Radio 5 live

"Muguruza looks very calm at the moment and that serve is a wonderful weapon to have, to get a few cheap points. Fantastic start from Garbine.

"No breathing space for Radwanska at the moment, feeling very constricted. Which side does she hit to in order to get onto an equal footing? Muguruza is accelerating on both the forehand and the backhand side."

Muguruza breaks

The second break point proves the charm for Garbine Muguruza as Agnieszka Radwanska fails to prise a vicious, top-spinning spitting forehand up of the floor.

She adopted that little crouching tiger position she favours, but even that was not enough.

Muguruza forces three break points

It's been a barrage of baseline battering-rams from Muguruza and Radwanska slips to 0-40.

That was gutsy from Garbine Muguruza. And I think Centre Court like the cut of her jib.

Hearty applause as the Spaniard, facing 15-30, refuses to be cowed by the situation and keeps hitting right up to the baseline. One up on Radwanska's toes and a booming ace help her wiggle out of the corner.

After Kate's glossy locks stole the show yesterday, sister Pippa has arrived with some sort of double-braid Princess-Leia style get-up and brother James is sporting the full Hoxton special on his chin.

As is Muguruza's calm. She sees off a spot of danger at 40-30 to back up her break with a hold.

Mark Woodforde

Former Grand Slam doubles champion on BBC Radio 5 live

"The first five minutes will be key for Garbine Muguruza, to get comfortable on Centre Court.

"Radwanska is like a sponge and absorbs the power so well. She has also got the knee-bend and does not give any territory behind the baseline.

"Much has been spoken about Radwanska's match against Madison Keys and how it will be a similar match against Muguruza today but Muguruza has also played Kerber in the earlier rounds so she will be used to Radwanska's style of play."

Muguruza breaks

Radwanska lures Muguruza into the net to see off one break point, but if the Spaniard is over-awed by the stage, she is hiding it well.

She crashes away a tub-thumper of a forehand to convert a second.

Never mind the vibration dampener on the strings, that was like she had a silencer screwed on the handle.

There's very few players who play like Agnieska. She's successful because she's done it the best.

"The grass helps her serve a bit but the good news for Muguruza is that on every return game, she has the chance to break if she plays the right way.

"So much of this is about how Muguruza handles the occasion."

These two have met on four previous occasions. Agnieszka Radwanska won the first two, Garbine Muguruza nabbed the two most recent.

Even if she wins, this might not be the biggest win of Muguruza's career. The Spaniard beat Serena Williams at last year's French Open.

Pete Dando has been looking after the BBGs for 26 years - combining it with his role as deputy head teacher at Sunbury Manor School, who have eight representatives this year.

What's the best part of his job? "When you see the kids go out on court it's a great feeling, as you know you've helped them achieve their aim. I've being doing this so long I have people in their 30s who come back and see me and still describe it as the best two weeks of their life," said Pete.

Leader of the pack

BBC

With places in the finals at stake, tension on the courts is rising - and it's not just amongst the players. Katie Wright met Wimbledon coach Pete Dando, who revealed that competition is just as fierce amongst the ball kids.

A team is made up of six children - four bases and two centres - who have been undergoing intense training in their specialist positions since the start of the year. The tournament starts with 260 ball boys and girls - better known as BBGs - but they are whittled down to the very best by the end.

Unlike the players, the BBGs don't know whether they've made the final until the actual day. "We tell the BBGs that there's no such thing as a bad court at Wimbledon but clearly in their mind they want to be on the best courts," Pete told me. "Everybody aspires to the final."

"She is telling herself off for bad shots and also giving her hitting partner a hard time for not serving to the right place, 'wider wider' she shouts."

Andy Murray column

Andy Murray's latest BBC Sport column reveals that a victory over Roger Federer nine years ago was the one that convinced him he belong in the game's elite.

"I was 19 years old the first time I beat Roger Federer and my coach stopped me before I got back to the locker room and told me: 'Act like you belong'," he writes.

"It was 2006 in Cincinnati, and Brad Gilbert gave me that advice in the corridor.

"I didn't really know what I was supposed to do at that moment but he wanted me to behave as though beating Roger wasn't unbelievably surprising to me."

"Ooooh, doesn't she make a lot of noise", says the woman next to me, as Sharapova lets out grunt after grunt. She is hitting some great serves though that get plenty of nods of approval from her coach.

Run, Andy, run

Andy Murray'sa cheeky blighter.

He couldn't resist a jibe at BBC Sport's newest pundit Andy Roddick, after he spotted the former world number one in SW19.

The Sun

The back page of the Sun, as well as touching on the illness afflicting Liverpool winger Raheem Sterling, carries Andy Murray's hopes that the crowd can whip up a supportive atmosphere despite having the ever-popular Roger Federer across the net for his semi-final on Friday.

It's sunny

BBC

BBC Weather's Simon King has been on the blower and it is good news, at least for today:

"After yesterday's rain and disruption, the next couple of days will provide a big improvement!

"Lots of sunshine expected over Wimbledon today with light winds and feeling warmer with a top temperature of 23°C. Friday is set to be even warmer (26°C) with more sunshine.

"Heading into the finals, we should be alright on Saturday with some bright or sunny spells but there is potential for some showery rain on Sunday so that'll need watching!"

A steely-faced Maria Sharapova arrives for practice on court five and gets straight down to business. No words exchanged with coach or hitting partner, she just walks straight to the baseline in silence. Been plenty of grunting since though...

Order of play

Garbine Muguruza (Esp) [20] vs Agnieszka Radwanska (Pol) [13]

Serena Williams (US) [1] vs Maria Sharapova (Rus) [4]

Jamie Murray (GB) / John Peers (Aus) [13] vs Jonathan Erlich (Isr) / Philipp Petzschner (Ger)

Add into that the prospect of a Murray in a semi-final in the last match on Centre Court - Jamie and partner John Peers in doubles action that is - and we have a final old day lined up on Centre Court.

This is it spelt out for those at the back and latecomers...

Before Serena Williams and Maria Sharapova meet in the day's second semi-final, Garbine Muguruza and Agnieszka Radwanska contest the first.

Muguruza, 21, is one of the fast-rising stars in the game. After making the last eight at the French Open in 2014 and 2015, she in up to 20th in the world.

Radwanska, a 2012 runner-up at Wimbledon, has a game full of guile and craft and is on the up after indifferent form and a short-lived coaching link up with Martina Navratilova.

Today's semi-final is their first meeting at Wimbledon since that row.

Serena Williams is two wins from repeating her 2003 feat of holding all four Grand Slam titles simultaneously.

Maria Sharapova is hunting for a second Wimbledon title since by beating Williams in the 2004 final as a 17-year-old.

There are plenty of sporting reasons to watch, but the pair's social lives add extra spice.

Time is a great healer, but is two years enough to patch up those sort of scars?

In the run-up to Wimbledon 2013, the gossip columns were abuzz with comments made by Serena in a Rolling Stone interview about an anonymous player and her partner, widely presumed to be Maria Sharapova and boyfriend Grigor Dimitrov.

Sharapova certainly thought Serena was talking about about her. She shot back with a barb aimed at Williams' relationship with coach Patrick Mouratoglou.

In the sanitised world of modern sport the gloves were off and claws bared between the two biggest names in women's tennis.

Serena: "She begins every interview with 'I'm so happy. I'm so lucky.' It's so boring.

"And, hey, if she wants to be with the guy with a black heart, go for it."

Maria: "If she wants to talk about something personal, maybe she should talk about her relationship and her boyfriend that was married and is getting a divorce and has kids."
