Angelique Kerber on BBC Two: "She [Flipkens] played well, going to the net and playing old tennis serve and volley.
"But I did a good job today, the last few games in the second set, I played some really good tennis and feel my rhythm is back and I am fighting for every single point."

"John McEnroe, if you started playing again, what would your world ranking be...in the women's game?"
Oh heck, it's all kicking off on 6-love-6.
Annabel Croft
Former British number one on BBC TV
That was so enjoyable, what a fabulous match to watch, full of creativity and flair. We saw volleys, we saw some unbelievable drop shots from both of them. Great fun. Kerber battled so hard and ran so much.

Kerber 7-5 7-5 Flipkens
Sealed with a lob, top seed Angelique Kerber is through.
The players embrace at the net, both smiling. That's great to see. They both some great stuff at the end.
Court One stands to applaud both from the arena.

First break point saved by Kerber with a sensational drop shot.
This is terrific stuff now.
Oh. What was I saying?
Flipkens misses a sitter of a volley and that brings up match point for the world number one...
*Kerber 7-5 6-5 Flipkens
Kerber is apologising but I don't think she means it as she clips the tape with a forehand and the ball dribbles over.
Flipkens picks up the ball and gives it a stern talking to.
The Belgian is much happier now! What a volley. Break point to Flipkens...
There's making your opponent move around the court and then there's Roger sending his opponent into the stands.
'A1 from Federer'
*Kerber 7-5 6-5 Flipkens
Angelique Kerber may be a little annoyed she isn't back in the locker room by now after missing that chance to serve this out.
She rattles a return right onto the shoelaces of her opponent and Flipkens can do nothing with it. That's the way to take out your frustration.
It brings up break point and again the German gets the ball to awkwardly dip low to Flipkens at the net.
Kerber breaks. She'll serve for the match for a second time.
More from Roger Federer: "My parents support me and see me play often and today they were delighted to be invited into the royal box. They were with Tim Henman’s parents and the Middletons' - who they have got to know over the years.
"I can relax on a day off tomorrow, it's one of those days where everyone will understand that I can lie on my couch and relax and watch tennis and not play with my kids as much as I normally do.
"But I’m sure it will be another great day in the Federer house."

Roger Federer's winning moment
Roger Federer speaking on BBC Two: "I struggled early on, I couldn’t get rid of the nerves and struggled to find my rhythm. I got back into the game after that and broke him; I started to play freely.
"I should feel comfortable here, and I do, but the problem is on grass if you’re struggling it can take a while. I wasn’t too worried.
"Nerves are a funny thing, sometimes you get horribly nervous and other times it’s a piece of cake. I'm happy it happened in the second round."
Here's how we are shaping up on Centre Court tomorrow:
And on Court One:
Kerber 7-5 5-5 Flipkens*
Maybe there is more in this match?!
Flipkens puts away a smash to bring up two break points.
"Come on," she roars to the crowd.
And she does takes the first break point! On we go!
Peter Fleming
Seven-time Grand Slam doubles champion on BBC TV
Roger Federer has the willingness to rest, to take time off and to keep his life in balance. I think that is what he does better than anyone else.
