Federer eases through his service game to love, having lost just 13 points on serve, to continue his domination of this match.

"Williams makes nine unforced errors to none from Cornet as the Frenchwoman races into a 4-0 lead in the second set, but the world number 24 flinches with the set in her sights at 5-1, 30-30, sending a forehand into the tramlines to give back one of the breaks. Williams looks low-key, but calm."
Federer wastes no time in breaking the Giraldo serve and moving to within a set of a place in the fourth round.
Australian and French Open semi-finalist Eugenie Bouchard takes the first set 6-3 on court three. Meanwhile, over on court 16, Angelique Kerber, who beat Heather Watson has lost the first set 6-3 to Kirsten Flipkens.
Giraldo gives himself a chance at 30-30, but Federer snuffs it out with some big serving to move to within one game of the second set.

"The further Federer gets ahead in this match the more it allows him to be adventurous and play with freedom. He is striking the ball so cleanly, there's no answer to this for Giraldo. Federer is absolutely relentless."
Giraldo stops the rot, holding serve for the first time in the set as Federer gives up the game with his 11th unforced error of the match.

Three-time Wimbledon singles champion on BBC TV
"I am so lucky to be sat in this box watching Roger Federer, he really is a joy to watch."
Blink and you'll miss it. Federer races through another service game to 15. Maybe Colombian Giraldo wants an early finish so he can get in time for the football, Colombia v Uruguay...

"Roger Federer is looking comfortable and seems to be moving forward and finishing points at the net and that is the Stefan Edberg influence. He knows now he will need to do that on some points. To me he looks stronger in the lower body because he has been healthy all year where he had problems with his back last year. He still thinks he has a Grand Slam or two in him. It is great to see him happy, healthy and a father of four!"
Giraldo looks "like a fish out of water at the moment", says BBC commentator John McEnroe. Federer takes full advantage, bringing up break point and taking it with a clean forehand winner. It's all too easy for the Swiss right now.
Federer, who has yet to face a break point in this match and lost just 10 points on serve, has hit cruise-control. The Swiss opens the door when Giraldo closes to 40-30 but in reality, Federer is always in control, closing out the game with a booming serve.
Federer makes the perfect start to the second set, breaking Giraldo to love. That's got to hurt.
Jiri Vesely has taken the first set 6-3 in his third round match against 19-year-old Australian Nick Kyrgios on court 17.
Eugenie Bouchard, who has reached the semi-finals of the Australian and French Open this year, is 3-2 up in the first set against Germany's Andrea Petkovic.
Eighth seed Milos Raonic trails Lukas Kubot of Poland 5-4 in the first set on court two.

ToniWater:, external Another Fed serving masterclass but he needs to get moved around more & made work harder for this win it will sharpen his game up
Danlami_kawu:, external I think @Rogerfederer is just playing for pleasure because I don't think he can ever win a Grand Slam title again.
And that's the first set put to bed, Federer easing through 6-3 without breaking sweat in a little over 30 minutes.
Serving to stay in the set, Giraldo heads towards the net in a bid to keep the point short. His volleys stand up to the test and he holds to 15.
It's easy, oh too easy, for Federer on his serve, the Swiss racing through the game to love.
Rafael Nadal has been reflecting on the success of the 'Big Four': himself, Roger Federer, Novak Djokovic and Andy Murray.
"I think for the young players, the example is we were fighters," says the Spaniard. "We were fighters for every single tournament, even if it's a Grand Slam, Masters 1000, 250.
"We were there fighting for the whole year, another year, another year, and another year. I think it's a good example for the kids, the motivation and passion for the game."
Piers Newbery
BBC Sport at Wimbledon
"If Serena had looked a bit shaky in the first two games of her match against Cornet, the American has looked anything but since returning after the rain. She breaks serve three times and reels off five games in a row to take the set 6-1, before sitting on her chair and closing her eyes in quiet contemplation. Serene, even."
