Also in the doubles, Britain's Jonathan Marray, the 2012 champion alongside Frederik Nielsen, has won through to the second round, beating Andreas Siljestrom and Igor Zelenay 6-4 7-5 6-4.

Not on his own. That really would have been impressive. John-Patrick Smith, an Australian, is his partner this time around.

"Nadal is right near our commentary box now and he is looking deflated. He can't believe what has happened to him again. I wouldn't bank on it not continuing so he has got to think of something. It is like Rosol has punched him in the stomach and he is having trouble breathing."

James Ian Robinson:, external Tough for Rafa when Rosol is going for & making winners from stupidly high risk positions. It makes him completely unpredictable!

Ian Rhodes:, external Nadal going out in the first week of Wimbledon starting to not feel like a shock anymore.

Gus Harris:, external This must be like watching the sequel of a horror movie for Nadal - he knows what's coming, but can he stop it?

A moment's respite for Nadal as his own serve, aided by new balls (behave) finally carries too much kick for gunslinger Rosol. But what can he do against his runaway opponent?

"Out on court six, Spain's Roberto Bautista Agut, who plays Andy Murray in the third round, is in men's doubles action. The world number 23 is in good form coming to Wimbledon, having won a grass-court title at s'Hertogenbosch in the Netherlands this month, and is showing his touch on the green stuff with some super volleys.

"The Spaniard is pretty vocal, both in celebration when he hits a winner and when he lambasts himself for an error. He also has impressive vocal support from his mum sat courtside who shouts "Vamos" every time he wins a point while clapping loudly."

It is a win for Bautista Agut and his partner Igor Sijsling as well, 4-6 6-4 6-4 6-4 over Britain's Kyle Edmund and Ukraine's Sergiy Stakhovsky.

Serena Williams on BBC Two: "I was out really late last night in a super fun doubles match. I even fell into the crowd - it was so embarrassing! It's tough (dealing with being the favourite) but I would rather it be looked at that way. The crowd here is so amazing. I've been coming here over a decade and it's lovely to see my fans."

Death or glory for Rosol - there's no margin for error. Is he just tightening up on his serve a little? To 30-30 before he lands a first one, but here they come - thunder out wide, lightning the other way.

"Serena was very disciplined today. Very well balanced in her shots and striking the ball very cleanly. A very matter of fact performance. She never faced a break point. A comprehensive win in which she looked comfortable and confident. She will be happy to have the afternoon off and reset for another day."

Sam Sheringham
BBC Sport at Wimbledon

"I'm pretty sure I expended more energy crawling out of bed this morning than Serena just did in dispatching Chanelle Scheepers. Watching the world number one live you are struck by how little she actually has to run.

"Her serves and groundstrokes are hit with such ferocity that she dictates almost every point from the middle of the baseline. Even her fist pump is a model of how to conserve energy. A subtle clench then ready for the next winner."

John McEnroe

"Rosol can walk down the King's Road and nobody knows who he is. I'm not sure how many people even know him in his own country, probably a lot more now than to years ago, but he's anonymous."

What can Nadal - 14 Grand Slam titles to his name, 64 career titles - do against this miracle man Rosol (total career titles: one)? Lord alive - huge return, 0-15. A dreamy forehand cross-court - 0-30. Nadal intot the net - 0-40. Service out wide - crashing winner down the line, and the twice champion is broken to love...

Drama on Centre Court. A lot less on Court One. Serena Williams strolls into the third round with a straightforward win over Chanelle Scheepers. Petra Cetovska or Alize Cornet is next in her path.

Just the solitary ace struck yet by Rafael Nadal, twice as many double faults as Lukas Rosol, just nine winners hit to Rosol's 18. The bare stats don't make great viewing if you're a Nadal aficionado…

Rosol walks into a casino. Changes all his cash into chips. Sticks the entire pile on black. Doesn't even wait for the roulette wheel to stop spinning. This game? Ace. Ace. Ace. Double-fault. Ace. Extraordinary.

Martina Navratilova
Nine-time Wimbledon singles champion on BBC TV

"It's like Scheepers' racquet is strung too loose. It's a bit springy. When you lose your confidence you swing less, you then lose the acceleration but because of the way the racquet is strung the ball is bouncing like it is on a trampoline. The strings are too lively.

"Serena gives that little extra flick of the wrist to her shots which gains that extra bit of spin - and therefore safety. Scheepers doesn't have a plan B - no net game, little backhand slice and her serve hasn't worked well because of nerves.

"Her biggest weapon is her forehand but Serena has been reading it very well and when she has had a chance she hasn't taken it. A good performance from Serena overall but her opponent hasn't forced her too much into anything."

Williams 6-1 4-1 Scheepers: Chanelle Scheepers sticking to the gluten free by dodging the bagel, but surely it is just a matter of time for Serena Williams.

Gasquet 6-3 7-6 (7-4) 4-6 2-1 Kyrgios: Still plenty of legs left in this one after Nick Kyrgios wins the third set.

A Ivanovic 3-2 J Zheug: Ana Ivanovic is level on serve in the first set of her second-round match against Jie Zheug.

Thundering forehand cross-court from Rosol, and all Nadal knew about that was the vapour trail as it went pass. He'll take aim at another, this time a backhand smacked down the line, but it nicks the tape and flies long. Nadal scampering, fetching, chasing - lots of slice to take the pace away, and Rosol finally misses with those haymakers.

If Rosol were a batsman he'd be Shahid Afridi. Boom boom - ace follows ace. Boom boom - crashing forehand, ace. It's like trying to stop a runaway train.

The eighth seed after his 6-3 6-4 6-4 win over Jack Sock: "It has to go down to a solid level of concentration and play. On grass, if you lose your concentration, you can be made pay.

"Overall my general confidence and specific grasscourt work has allowed me to not to think about slipping on the grass and just think about my play and how I need to play."

Raonic had to pull out of the 2011 tournament after suffering a hip injury in a fall on court.

Jack Blackburn:, external You can sense an upset here. Rosol, buoyed by happy memories, is playing without fear of Nadal, who needs to dig ever deeper.

Derek Nish:, external Nadal looks like a man whose confidence on grass has been shattered. Unrecognisable to the player who won in 2008/2010.

Jim Patterson:, external Love watching Rosol when he is playing like this, incredible hitting and a massive test for Nadal here.
