Gilles Muller beat France's Julien Benneteau in the first round and also progressed to the second round of the men's doubles with Britain's Jamie Delgado, who is interestingly also his coach, in a five-set battle.

Delgado, 37, is contesting his 23rd consecutive Wimbledon tournament, an all-time male record and a remarkable effort.

But back to the matter in hand on Centre Court, where it's going with serve. Muller leads 2-1.

You have seen the thumb-jabbing celebratory twirl from Jo-Wilfried Tsonga. Now there is a new step to learn. Get across the Frenchman's post-match toe-tapping on the BBC Sport website.

And when you are done with that enjoy the condensed madness of Gael Monfils. Strops, serves that land at the line judges feet and brilliant soft-touch volleys. It is all there.

"Muller has won four tournaments on the Challenger circuit, three in a row, that's going to give you confidence and he'll certainly fancy this opportunity."

The warm up is over, it's time to get down to business. Gilles Muller to serve first, Roger Federer to receive, with five-time Olympic rowing gold medallist Sir Steve Redgrave watching on from the Royal Box.

Andrew: There are few better or more enjoyable sights in world sport than watching Roger Federer play tennis on a grass court. Such elegance, precision, economy of movement and grace. The greatest of all-time. Wimbledon title number eight anyone?

Seven-time Wimbledon champion Roger Federer strolls out onto Centre Court to a rapturous reception. As they start their warm up, Sue Barker warns that it could rain shortly, which isn't ideal.

"There were so many positives for Heather. She wasn't in it mentally at the start but then she got engaged and you could see the response from the crowd. She can leave the court with her head held high. She has a big heart, she is such a fighter."

Sharapova 6-2 1-0 Bacsinszky: Sharapova on cruise control out on Court One. The break is already tied down in the second set and that might be the last that Timea Bacsinszky sees of her.

Janowicz 1-1 Hewitt: This has all the hallmarks of a late-evening ding-donger. I reckon if you have a ticket for tomorrow there might be some leftovers for you.

Isner 7-6 (19-17) 7-6 (7-3) 1-1 Nieminen: This is not one for the faint-hearted. John Isner ties down the second set in a second successive tie-break.

Vekic 4-6 Zvonareva

Angelique Kerber, who beat Heather Watson in three sets: "It was a really tough match Heather is a great, talented player and I am really happy I won. I was trying to be aggressive and focus on the moment. Heather has a very good future and I wish her all the best, she is a great player and a great personality."

"This will not just go down as a pure defeat for Heather. She won respect in the way she came back in the second set. It was so important for her to win that. It showed positive signs. She gave the third away to some extent but if she had lost in straight sets it would have hurt her."

"Very experienced and consistent performance from Angelique Kerber. Watson doing such a great job pulling out that second set but she ran out of steam and just wasn't able to continue it. Kerber just proved to be a little bit too consistent for Heather Watson."

Watson is going down fighting, the Briton wrapping a backhand back into court to bring up game point. She tries to do the same on the forehand side in the next, but that goes sailing into the tramlines.

Deuce then match point Kerber, but she pulls a forehand wide. Deuce again before Kerber creates her second match point. Watson keeps battling and we're back to deuce. A third match point then goes wanting. But the German won't be denied on the fourth as Watson dumps a backhand into the net.

Eugenie Bouchard against Andrea Petkovic? That sounds like it will take some beating as a third-round match-up.

It is on the cards after Bouchard completed a quietly efficient win over Silvia Soler-Espinosa and 20th seed Petkovic put away Irina-Camelia Begu.

Lindsay Davenport
1999 Wimbledon champion on BBC TV

"Kerber got tight in the second set trying to close it out and if you're Watson you want to keep that in your mind."

The wheels have come off the Watson bandwagon and it looks all but over as Kerber holds to love. The Briton's unforced error is out of control.

Nick Bollettieri
American tennis coach on BBC Radio 5 live sports extra

"The sad thing is Kerber showed signs of perhaps her back hurting, walking gingerly. You just can't make these sorts of unforced errors."
