As this match goes on Serena is turning up the decibels. What started as a “come on” earlier in the set has become huge roars from deep inside her.

Ooft. Stonking body serve from Arantxa Rus for her first ace and Serena ends up flashing her racquet at fresh air.
Rus takes a bit of pace off the ball and Serena is annoyed as she fluffs her forehand into the net for 40-15. A long backhand, and the Dutch holds to 15.
Wawrinka 1-6 4-3 Dimitrov*
It's turning into a cracker on Centre Court, with Stan Wawrinka breaking Grigor Dimitrov in the second set only for the Bulgarian to hit back just a moment ago.
Sixth seed Dimitrov stormed the opening set against the Swiss, who is attempting to find his form after a long lay-off with a knee injury.
*Swan 3-1 Begu
And it's Katie Swan... the 19-year-old from Bristol is taking on Romania's Irina-Camelia Begu out on Court 14.
She's just broken to take a 3-1 lead in the first set.

The American looks all out of the next point but she darts across, seeing her opponent rushing forward, and whacks a winner down the line for 40-15.
A huge yell from the American as she passes Rus with a backhand to hold.

Serena is really trying to find her match focus. Obviously she's been practising but because of the injury she had she has not played as many matches as she's used to.
Her preparation is different and it will take her a little bit longer than in previous years to get into her stride.
S Williams 3-2 Rus*
Great serve out wide from Serena, and she lets out a cry as she hits the follow-up backhand winner.
Rus defends will to draw the error out of Serena's forehand, but she can do nothing about a huge ace for 40-15, and Williams hits a forehand winner to close out the game.

The hill/mount is packed. Everybody is trying their best to fight the heat - cool drinks to covering themselves in a blanket. Not sure the latter will work.
With Andy Murray absent, BBC Sport thought it would ask one of the attendees what the geological section should be (temporarily) renamed.
Cue Andrew Crampton and Charlotte Royle from Manchester, who queued for three hours to get in. Bet they were glad they ran into me.
After about 10 minutes of trying to apply alliteration the pair came up with....
"Mount Roger"
We'll take that.

Advantage Rus, as Serena hoicks a return of serve into the net.
Another chance for Serena to go cross-court, Rus stranded to one side - but the American misses a forehand, and we're staying on serve.

And save it, she does!
Serena is nailing these shots but the wind picks up a forehand and drags it over the tramlines.
Deuce.
S Williams 2-1 Rus*
Serena aims a backhand down the line and, er, misses by some way.
One more break point for Rus to defend....

Court One seems to be windier than the others, today, as Arantxa Rus double faults for 0-30.
The Dutch gets on the board as a lob from Serena lands out, but some deep hitting doesn't work for Rus, and two break points come rattling along for Serena.
Wawrinka 1-6 2-1 Dimitrov*
That's better from Stan Wawrinka in the second set, starting to find his feet a little.
The Swiss lost the first five games on the spin on his way to giving up the opening set against Grigor Dimitrov, but has held serve so far in the second over on Centre Court.
It wasn't easy for him earlier...

S Williams 2-1 Rus*
Oh, that is superb from Arantxa Rus!
She comes up to the net and Serena throws shot after shot at her, trying desperately to pass her. Rus keeps everything out, hands and feet moving so quick, and eventually she volleys a backhand way out of Serena's reach.
Back on serve!
Rus breaks straight back against Serena Williams
*S Williams 2-0 Rus
The first hint of a "come on!" for Serena as she darts to the net and lets a forehand winner fly.
One break point still to fend off...

Fine defence from Arantxa Rus, keeping out several big shots from Serena Williams, and eventually it's Serena who errs on the forehand.
