Roger Federer's secrets revealed: Split-steps, heavy rackets and a killer forehand
2:48PM
Federer 6-2, 7-6 (7-5), 2-2 Anderson* (* next server)
Federer holds to love and this set isn't one for the neutral. Fortunately, nobody's neutral, they all love Federer and are happy to see him land some scintillating serves. Who needs rallies?
2:47PM
Federer* 6-2, 7-6 (7-5), 2-2 Anderson (* next server)
A low-key set so far as neither player seems capable of grinding down the other's serve. Anderson takes this one 40-15 and Federer was basically a spectator. Is the Swiss waiting to strike? Some big cheers in the crowd as someone yells something that must've been funny. Game Anderson.
2:42PM
Federer 6-2, 7-6 (7-5), 2-1 Anderson* (* next server)
A line judge dodges a Federer ace with almsot as much skill as the ace took itself. Federer holds to love. This set is flying by. Some monster serves from Federer in that one.
2:40PM
Federer* 6-2, 7-6 (7-5), 1-1 Anderson (* next server)
Anderson wrestles Federer back to 30-30 with an ace, and another big serve gives him 40-30. Smashes home for the game.
2:37PM
Federer 6-2, 7-6 (7-5), 1-0 Anderson* (* next server)
Anderson not demoralised by that tie-break loss, he fights his way to 40-30, but Federer seals with an ace.
2:32PM
Federer* 6-2, 7-6 (7-5) Anderson (* next server)
Ace for Anderson and it's 1-0, Federer nets a shaky forehand, 2-0.
Finally Federer finds his feet and wins a wonderful backhand rally. Back on serve after an outrageous sliced backhand from the Swiss, 2-2. Federer takes another Anderson service point, and Federer's up a mini-break.
Federer with a rare challenge that is nowhere near correct, but no matter as he backhands down the line for 4-2. 5-2 now and all that hard work from Anderson is flying out the window. Set point Federer, but he goes uncharacteristically long. And Anderson's back in it!
Still set point at 6-5 but Anderson's back on serve. Can he level it up?
No, Federer takes it. Still no sets lost for the great man. 34 consecutive sets for Federer at Wimbledon.
Federer takes the second set 6-2, 7-6 (7-5)
2:23PM
Federer 6-2, 6-6 Anderson* (* next server)
Anderson goes 0-30 up. Federer in danger of losing his first set at Wimbledon since 2016. An angry ace gets him back in. Anderson can't return the next either. 40-30 and that's why he's won so many slams. Game, and it's a tie-break.
2:19PM
Federer* 6-2, 5-6 Anderson (* next server)
This one has tie-break written all over it. Federer has no answer to Anderson's first three serves, and we're at 40-15 in under a minute. A lucky return and it's 40-30 ... Federer has a look in here, but goes long.
2:16PM
Federer 6-2, 5-5 Anderson* (* next server)
Some more questionable forehands from Federer as he goes wide. Anderson has sorted out his return of serve in this set, but as I type that Federer lands two aces in a row for 40-15. Anderson steals a point but another ace seals it.
2:13PM
Federer* 6-2, 4-5 Anderson (* next server)
Anderson a contender now though, he holds to love. It isn't pretty tennis, but it's effective, and Anderson won't mind.
2:11PM
Federer 6-2, 4-4 Anderson* (* next server)
Wonderful lob by Anderson but it's not enough, Federer takes the game and the new balls are out. I made the mistake of getting some water during that one. Federer waits for nobody.
2:07PM
Federer* 6-2, 3-4 Anderson (* next server)
Anderson races to 40-0 with some big serves. He needs more games like this but this is a much better performance from him in this set. He seals the game with a cross-court backhand that flies pass Federer.
2:05PM
Federer 6-2, 3-3 Anderson* (* next server)
Federer a little vocal there as he brings us back to 15-15. Not as calm he looks?
An ace for 30-15, but Anderson grinds his way back in and has another break point! He saves it and that's as loud as I've heard Federer this year. So pumped. He takes the game.
A little frustrated at dropping off his first set form.
1:59PM
Federer* 6-2, 2-3 Anderson (* next server)
Terrific rally, and Anderson nets a Federer cross-court forehand. An ace brings us back level.
Oh boy, that's one for the highlights reel. Really unbelievable. Federer slips, he's in all sorts of trouble as Anderson puts him at the back of the court, but Federer somehow, somehow, LOBS the 6ft 8 South Africa with a perfect shot on the turn. He wasn't even looking.
Break point Federer, but he doesn't take it. He gets another, and Anderson nets. Back on serve.

1:54PM
Federer 6-2, 1-3 Anderson* (* next server)
The Swiss doesn't seem too fazed though, racing to 40-0 without Anderson getting a shot back. That's game in just over a minute.
1:52PM
Federer* 6-2, 0-3 Anderson (* next server)
Simple, he consolidates with a hold to love. Anderson back in this now, Federer just looking a little out of sorts in those last two games. He never really had a look in as Anderson landed some big serves and Federer started finding the net.
1:49PM
Federer 6-2, 0-2 Anderson* (* next server)
Anderson with a look in here at 0-30 after Federer's forced into two errors.
Two break points! He takes the first! Where did that come from? Federer broken for the first time this Wimbledon.
Anderson breaks
1:47PM
Federer* 6-2, 0-1 Anderson (* next server)
Oh dear. A Federer slice and Anderson nets, but that wasn't even close. Unforced errors are piling in on the rallies.
The South African finally gets to the net and Federer can't get past him. He springboards to 40-15, he could really do with an easy game here, but flails at a forehand that allows Federer back in. Deuce. Sealed with a few big serves.
1:40PM
Federer 6-2 Anderson* (* next server)
Blink and you'll miss it tennis from Federer here as he holds to love and takes the first set. A drop shot at the end has the crowd in raptures, words can't do it justice. Frightening stuff.
Federer takes the first set 6-2
1:38PM
Federer* 5-2 Anderson (* next server)
Anderson's unlucky as he hits the net cord, giving Federer all the time in the world to wind up a forehand winner.
Break point Federer as Anderson goes long. Superb return from Federer and Anderson goes long again. Federer's return of serve just comes back so deep and fast and almost shocks Anderson into an error. This is a procession at the moment.
Federer breaks
1:34PM
Federer 4-2 Anderson* (* next server)
Anderson preserving his energy as he watches a backhand pass him from metres away. He goes for the next, a Federer drop shot, but he cannot reach it and this game is already over.
1:32PM
A rare Court 1 appearance for Federer
Federer hasn't played on Court 1 since 2015. They've kept him off Centre for this one, perhaps because Nadal is on there later? Like keeping the bride and groom from seeing each other before the wedding/final?
1:30PM
Federer* 3-2 Anderson (* next server)
Double fault from Anderson to kick us off, but he takes the next with a 133mph rocket that Federer can hardly return - but does, before Anderson fires a forehand to win the point.
A big serve for 30-15.
The crowd love that! A classic baseline rally wakes everyone up before Anderson nets. Federer goes long with a forehand but redeems with another that Anderson can't even get close to. Deuce.
A master forehand from Anderson this time, a graceful player in his own right despite his height.
He can't take the first or second advantage points, but gets the third. Hard work.
1:23PM
Federer 3-1 Anderson* (* next server)
First real rally of the game but Anderson nets after heavy forehands from Federer. 30-0 and we see those rare glimpses of mortality from RF as he goes long with the court gaping. A smash takes us to 40-15, and an ace seals it.
1:20PM
Federer* 2-1 Anderson (* next server)
Anderson goes 15-0 with a big serve, before Federer returns the next at pace and Anderson nets.
Federer responds with a net of his own, and then goes wide with a backhand for 40-15.
A long serve return and that's game. Anderson on the board. A relief for the South African.
1:17PM
Federer 2-0 Anderson* (* next server)
Federer kicks off with an ace, and then somehow lands a drop shot from the baseline. Ridiculous, he's just playing around.
40-0 before you can blink as another serve never comes back. And that's game. Pace.
1:16PM
Federer* 1-0 Anderson (* next server)
Federer races into 0-30 and immediately gets a look in for the break. Oof and Anderson whacks a forehand just wide to hand Federer three break points.
He finally lands one of those famed big serves to get on the scoreboard,
Blimey, and there's break as Anderson nets. Federer not messing around here.

1:13PM
Federer 0-0 Anderson* (* next server)
Anderson gets us underway on serve
1:10PM
Aces
Unsurprisingly, Anderson has 96 aces to Federer's 46 in the tournament so far. It helps when you can almost reach the net.
1:07PM
The players emerge
The players emerge from the tunnel. Kevin Anderson gets a push from the umpire after taking a little to long at his chair ... just because you behave like Nadal doesn't mean you'll play like him.
Federer keeps his jacket on for the warm up.
Both players in white ... obviously.
1:03PM
Green green grass
The grass at Wimbledon still looking luscious despite the fact it no longer rains in London. If this heatwaves lasts much longer they made need to open up Wimbledon as the capital's botanical sanctuary.
12:57PM
Imagine ...
Imagine being the greatest player ever to play your sport, respected all over the world and loved by millions ... but also having a great sense of humour. It's just not fair.
Well worth checking out Federer's reaction when asked about concerns that the Wimbledon final and the World Cup final will take place on the same day.
