Nadal 3-2 Del Potro*
The Nadal forehand is causing serious damage. All the talk was about the Del Potro forehand pre-match but in five games Nadal has hit six forehand winners.
3-2.

The serving direction from Del Potro is going to the forehand of Nadal, and he needs to be careful not to be too predictable with that because Rafa will pick up on that.
*Nadal 2-2 Del Potro
Andy Murray is reeling off stats on comms. He's a proper tennis nerd. I love it.
Juan Martin del Potro is into the net in just a couple of steps with his tree trunk-like legs but he's stranded by a fizzing Nadal backhand.
The Spaniard gets to deuce but two big serves see DelPo draw level at two games each.

Every point counts double in the fifth set. It is very expensive! Every now and again, you start thinking about who you are playing. It is only human. It is the hardest thing to do in tennis - stay in the moment when it matters most.
*Federer 6-2 7-6 (7-5) 5-7 4-6 3-3 Anderson
Big, big serve wide out for Kevin Anderson and it brings a double fist pump out of the eighth seed. He follows it up with a huge backhand that just nibbles the chalk on the tramlines.
Punchy from Anderson! He shuffles around a Federer ball that just stands up in mid-court and lashes it beyond the Swiss.
A superb turnaround in this game to hold.

Calvin: Did not need Roger to drop a two set lead today. My nerves are already shot because of England.
Alex: Federer deliberately turning his match into a 5-set classic in response to people saying his matches are boring so he should play on Court One.

Oops, Kevin Anderson should have finished off that point at the net but he gives Roger Federer a sniff and the scrambling Swiss scuttles in to sweep a passing forehand beyond the giant South African.
Anderson leaps into a forehand - long! 0-30...

What a journey Kevin Anderson's tennis career has been. He got into the game via that game swing ball! His father then built a wall to practise off. Very humble beginnings and now he is in one of the biggest stages in the world. Can he transform this into one of the biggest wins of his career?

Court One is a pressure cooker at the moment, the crowd almost bubbles over after Roger Federer slings down successive winners.
The Swiss gets great depth on a sweeping forehand and holds to love.

"Let's go Roger, let's go..."
Hmmm, this Court One crowd aren't as tuneful as the dedicated lot you normally get over on Centre - a chorus to match his performance, perhaps.
The top seed attempts to eke out forehand a return to a wide Kevin Anderson serve, but it drops short. The South African follows it up with just his third double fault of the day.
It's a minor blemish on the eighth seed's service game as he skips around a forehand and wrong-foots the 36-year-old.

One of the parts people feel is a weakness in Nadal's game is his second serve, but it is not easy to attack, there's a lot on spin on them.
Nadal 2-1 Del Potro*
Both Rafael Nadal and Juan Martin del Potro are big football fans. Rafa is a supporter of Real Madrid and DelPo a follower of Boca Juniors.
They've got less than three hours if they want to be done to see tonight's semi-final.
The rallies in Nadal's service game are lengthier than Del Potro would like. Rafa holds.

Federer has missed a lot of big serves but he's got through. He is on the edge though. Kevin Anderson just looks so confident! He has no nerves, he looks so calm and he's just enjoying being up against Roger Federer.

Andrew: Federer losing sets better not be like London buses.......
Saral: Anderson has the momentum going into the fifth. What does Federer have? Experience, experience and experience. He's been here before and done it on many occasions.
Federer 6-2 7-6 (7-5) 5-7 4-6 2-1 Anderson*
It's like someone's filled Roger Federer up with the wrong petrol - he's stuttering and stalling through this quarter-final. Will he just about make it home?
Kevin Anderson senses an opportunity as the Swiss skittles a volley into the net for 0-30, before Federer grinds his way to 40-30.
"Come on," he shouts after a big hold.
'Magnificent' - Anderson takes Federer to a fifth set in the men's quarter final
*Nadal 1-1 Del Potro
Boom. Eye brows are raised in unison in the Centre Court crowd as Juan Martin del Potro launches a humongous ace on his first serve and follows it with another.
Wow. There's another. Nadal is swinging at fresh air. Not much you can do there.
*Federer 6-2 7-6 (7-5) 5-7 4-6 1-1 Anderson
Lovely, seamless motion in the Roger Federer backhand as he swivels into a one-hander down the line and Kevin Anderson clips his response long.
The South African hits back with a thumping ace that booms off the hoardings and rings out around Court One.
That's some top serving from the eighth seed. Hitting his spots. He holds.

I think Nadal will be looking to put a high percentage of serves in play and dictate with his forehand. I think he will be looking to push into the backhand side of the court.
Any time you go into Juan Martin del Potro's forehand he can be dangerous.
Nadal 1-0 Del Potro*
Rafael Nadal is grunting right away and does well to come back from 0-30 behind to take his opening service game.
Andy Murray has now made his way to the commentary box for this one. You can watch/listen at the top of this page or on BBC Two.
