Boris Becker
Three-time Wimbledon champion on BBC TVThere are a few more unforced errors creeping into Federer's game in the second set. It would have been hard to keep up the level he set in the first set but come on Roger, we expect perfection!

More shouting from Federer! My Swiss (of any variety...) isn't up to scratch.
The top seed fights back to hold.

*Federer 6-2 2-3 Anderson
"Come on," shouts Fed. That's a rarity... the Swiss means business, and knows he's in a match on Court One.
He flops a backhand long to make it 30-30 on his serve, and now another break point for Kevin Anderson.
Here's how Federer took the first set...

BBC Sport at WimbledonRoger Federer is no longer a break down at Wimbledon - the world has returned to normal in London.
Apart from England playing in a World Cup semi-final and a heatwave that shows no sign of stopping...

John McEnroe
Three-time Wimbledon singles champion on BBC TVDjokovic has been excellent when he has moved inside from the baseline.
Nishikori hasn't won a single point at the net and doesn't look in hurry to get there either.

Djokovic 6-3 1-1 Nishikori*
Kei Nishikori is looking bedraggled at times here. His elbow is held together but tape and he takes an age between points, dragging his toes along the baseline.
Every now and again he burst into life but not in this game. Djokovic holds in a flash.

*Djokovic 6-3 0-1 Nishikori
Novak Djokovic is not happy. He slaps his thighs has a backhand sails long. He had plenty of opportunities to break there but misses out.
The crowd are getting behind Nishikori. Not sure Novak will like that.

Kevin Anderson wraps a forehand into the tape, and Roger Federer breaks back!

Federer 6-2 1-3 Anderson*
Kevin Anderson dusts himself down after that sublime Roger Federer winner and rattles back to deuce.
But then the South African sticks a framer long. Break point number three...
What a shot!published at 13:58 British Summer Time 11 July 2018
Federer 6-2 1-3 Anderson*
Magnificent from Roger Federer. He's made to run, but dashes across court to meet a forehand with serious venom.
A double fault from Kevin Anderson gives Federer a sniff at 15-30, and the most outrageous backhand, lobbed winner as the Swiss sprints back towards his own baseline, and slips mid-swing, gives him two break points... that was something else!

Djokovic 6-3 0-0 Nishikori*
Ouch. That's gotta hurt. Nishikori dumps a forehand drop shot into the net from inside the service box. He knew the moment he hit it and looked to the ground in disgust.
Break point Djokovic.
This game has been going on 10 minutes.

Alice: Anderson absolutely deserves that break. Played some well-conceived & aggressive points. Although I think Federer is amazing, I want to see a MATCH.

John Lloyd
Former GB Davis Cup captainGrass court tennis is very different to any other tennis because you only need one break of serve to run away with it. On grass you get so much more confident because the return game becomes easier and then you only have to concentrate on your own serve.

Right then, can Roger Federer get on the board in this second set? A question we didn't expect to ask...
Anderson has angered the beast. The stern-faced Federer steams to a love-hold.

Pete Sampras’ all-time record remains untouched at 118.

Djokovic 6-3 0-0 Nishikori*
Kei Nishikori needs to get himself going again here at the start of this set. He drops 15-30 behind and then barks "come on" as he wins the next point.
He can't wriggle free of Djokovic. Deuce.
