A serve comes down with such force from Murray that it knocks a chunk of grass out of shape.

A little trot to the net and a slam from Murray takes him to three set points.

Ninth seed Kei Nishikori came through in four sets against Sergiy Stakhovsky earlier today.

En route, he pulled off an amazing hot dog winner.

Consecutive little flicks from Brown end up buried in the foot of the net, bringing about a sigh from the Centre Court crowd and 30-30 on the board.

An ace restores Brown's lead but another delicate backhand, this one played off the hip, hits the net again.

A lacksidasical return from Brown and Murray comes charging to the net like a rhino leading the pack, and he'll now serve for the second set.

Brown has got a bit too much caught up in the moment. God forbid, play some percentage tennis.

Brown spins his racquet from hand to hand as he waits for Murray, who bends before shovelling a lovely two-handed backhand beyond his opponent.

An almighty service game from the Brit. He holds to love. He's been very impressive with the way he's dealt with Brown's aggression.

The tables have turned on Court One.

Qiang Wang, the world number 55, has won four games in a row to take the first set against tenth seed and former champion Venus Williams.

The Chinese 25-year-old is in the second round at Wimbledon for the first time in her career. Can she pull off an unlikely win here?

Advantage Murray, courtesy of a big return that Brown nets.

Murray reads his opponent's serve very well, and gets his reward as Brown sends the ball wide. The familiar "come on!" rings out across Centre Court.

Murray is hirpling around slightly but still finds the energy for an almgihty backhand down the line.

And that's a pin perfect lob! Brown just stands and applauds as the ball ges over his head and bobbles onto the line to take him to two break points.

Brown saves the first, delicately popping over a fiery Murray forehand, and he saves the second with an almighty stretch at the net for yup, you guessed it, another drop shot. Deuce.

Remember Daniil Medvedev - the 21-year-old who stunned US Open champion Stan Wawrinka in the first round on Centre Court?

Well, he's out. But that's not the story.

Medvedev was 2-0 up in the deciding set but suddenly found himself 5-2 down against Ruben Bemelmans of Belgium - and the Russian had become more and more irate with the umpire's decisions.

He asked for her to be removed, but the supervisor said no. After he lost the match, he got his wallet out and started throwing coins at the bottom of the umpire's chair.

What a way to bow out.

Ridonkulous. Murray is back pedalling to reach a deft flick from Brown, he gets to it, lobs over a sure winner - and Brown, at full stretch, meets it and dashes back a forehand winner.

Murray takes a bit of pace off his serve and it works, Brown floating the ball into the net, before two aces goes firing past Brown's nose. Cracking serving.

Murray is doing the basics very well. He has only made just one unforced error. Impressive.

Brown has a really strong first serve, sending Murray sprawling, and he consolidates as Murray works a forehand wide.

The Brit's not best pleased that he let that break point slip. He wraps the ice towels around himself with a bit of extra vigour.

Another double fault from Brown to begin his service game, but he follows it with a lovely backhand that Murray can't get near.

Excellent judgement from Murray though, drawing the error out of Brown's forehand to bring up two break points.

He saves the first as Murray's backhand misses the mark, then the second with a fine forehand winner.

A cracking serve from Brown gives him the advantage while Murray furiously chunters to himself, but even Brown can't meet that drop shot. Deuce

Eesh. A love hold for Murray, Brown casually flicking the ball long on consecutive occasions.

Dustin Brown has a fantastic repertoire - the sort of stuff we get paid to do in exhibition matches, he does on the Centre Court at Wimbledon.

Andy has unbelievable hands and won't mind these flicks and tricks - he's not far behind in matching those skills.

And he'll be thinking that Brown will play a fancy shot when he's under pressure and he can take advantage.

There's something delightfully casual about the way Brown plays. He feints a drop shot and then puts a bit of extra zip on it, his arm barely moving, to race to a 40-0 lead.

A drop shot goes wonky but that's the only error for Brown as he holds first up.

Down comes the serve, Dustin Brown gets just a hint of racquet on it, and the defending champion takes the first set.

That took just over half an hour for the Brit.

Venus Williams is turning the screws on Court One.

She has the advantage after deuce and watches Qiang Wang hit a forehand long past the baseline for the first break of the match.
