There's now Wimbledon coverage on BBC One and BBC Two. How's about that.

You can also watch live streams of every court on this page.

Annika Beck has the Centre Court crowd on their feet as she dashes from one side of the grass to the other at break-neck speed to fly over a forehand winner. How did she get that?!

It fends off a Serena Williams break and she holds serve.

However, it's not long before Williams slams an ace down court to hold to love and take the first set.

Annika Beck came back against Heather Watson to win. When you have looked at defeat, it gives you a strengthening feeling. 

How is she going to threaten Serena when the going gets tough? She has to rely on Serena making mistakes.

Serena Williams is very much in control. She is so tough. Even when she loses the serve at the beginning of the match, she is able to break back very quickly. The timing of her serve is absolutely perfect.

After a mini wobble, Serena Williams appears to be back on track.

The world number one grabs two breaks against Annika Beck, as well as holding twice on her own service game to move 5-2 up.

That's more like it from the six-time champion. 

Karen Turner: For such an incredibly accomplished player, it's wonderful how grounded a person Roger Federer is. Pure class & complete gentleman.

Chris Thornton: I'll always support Murray, but Federer is extremely difficult to not love. Exceptional tennis player / nice guy / great hair.

BBC Two

Roger Federer speaking to Sue Barker: 

"With all the interruptions I didn't see all of Novak's match. It was clearly a huge surprise. I played Sam last year and I thought he was very dangerous.

"You could always maybe think Sam might have a chance in a set or two but I didn't pick him to win, especially with Novak's method.

"Now is a time to take a step back and see what an incredible performance Novak has had in the last year. He does sometimes give you chances to close him out but not many guys can do it. Sam was able to.

"I’m sure this is just a hiccup for Novak. As long as he is healthy he will be unbelievably tough to beat."

Annika Beck is doing really well and is very much in charge at this point. I'm sure she is feeling a bit nervous. Anyone playing Serena Williams at this stage of the tournament would. But she seems very well and must be feeling pretty good about her chances right now.

Serena Williams has break point on Annika Beck's first service game, but the German manages to take it to deuce before holding out. 

A double fault on Williams' service game leaves the pair on 30-30, and then the defending champion slams a backhand long to hand Beck a break point.

It looks like she's dished out another double fault, but Williams is right with a Hawkeye challenge.

However, Beck does eventually nab the game. A great start for the world number 43, who is making her debut on Centre Court. 

BBC Two

Roger Federer speaking to Sue Barker:

"My first Wimbledon is the title I'm most proud of. Without that one, who knows where my career was going to go? 

"All of a sudden it all picked up and all made sense to me. When I won that final point it was the most beautiful moment of my life a a tennis player.

"The win over Pete Sampras is still the most important and beautiful match I've played but it didn't have the golden trophy at the end!"

Timea Bacsinszky had no right to win this point.    

Sadly it wasn't enough to avoid defeat against birthday girl Anastasia Pavlyuchenkova over on Court Two.

Svetlana Kuznetsova has snatched a set back against Sloane Stephens to take it to a decider on Court One.

You can watch that match on this link.

Serena Williams and Annika Beck are out on the grass knocking up before their third round match gets under way.

Williams absolutely towers over her pocket-sized German opponent. This could be an interesting match-up.

It does feel quieter at Wimbledon on Middle Sunday. On another day we might have had an extra 20,000 people. On fourth round Monday, for example, there will be more than 40,000 people."

Roger Federer's been speaking to Sue Barker on BBC Two:

"It was a fun first week, especially with the match against Marcus Willis.

"It was very cool, I loved the story and I loved his reactions and how the match went. He had a lot of pressure not to win games. I always knew he would win games.

"I had to prepare myself in a way that I knew he would be a top 50 player. I loved that he soaked it up. He really enjoyed it and he played great tennis.

"He toyed with me! It was a great atmosphere to bring to Centre Court. He has a great serve and I couldn't read it. I just tried to stay aggressive."

Former Australian player Louise Pleming: "I’m very impressed with the way Coco carried herself today. She knew what she needed to do and she executed extermely well. 

"She looks so confident out there and surprisingly so comfortable to be on Center Court. She enjoyed every moment of that. Roberta did what she could but she was the backseat passenger. Coco was driving that match."

Vinci worked hard but some of Vandeweghe's play was too good.
