Venus 1, Serena 1: Venus has one of her best service games of the match so far but doesn't look even the remotest bit happy about it.

Second set - Venus 0, Serena 1: Serena takes her form from the tie-break into the first game of the new set, winning to love on her serve.

Serena takes first set on the tie-break, 7-3: Hawk-eye fans get their first challenges - both from Serena, and both go against her. Despite that, she wins the tie-break quite convincingly - finishing with a fantastic lob-shot.

Venus 6, Serena 6: Serena takes the first set into a tie-break - who would have predicted that! Some more nice aces from the younger sibling.

Venus 6, Serena 5: Easily the best rally of the match so far in this 11th game and Serena wins it with some style, taking control of her sister's second serve. She does it again to make it 30-30, only to then put an easy return into the net. I still think Venus looks the most likely to be broken - but still with serve so far.

Venus 5, Serena 5: Serena's serve continues to fire and, despite Venus getting a lucky net cord, looks very commanding. Wins the game with a sweet forehand down the line.

Venus 5, Serena 4: Serena puts in the running yards as she makes Venus work for the ninth game, but is let down by a few stray shots.

Venus 4, Serena 4: Serena goes down to 15-40 to give Venus the first break points before a big kicker of a second serve and some more aggressive play brings the game back under control. She finishes off with two aces - nice.

Venus 4, Serena 3: This game begins with a wonderful rally that only ends when Venus slips. A bit more aggression from the older sister on the next point to level; then Venus wins another long rally; serves up her first ace; and then an unreturnable first serve to take the game. Simmering a little now.

Venus 3, Serena 3: Another ace from Serena as she wins another game to love - best serve McEnroe has seen in the women's game, he says.

Venus 3, Serena 2: Nice double-backhand down the line is the first decent winner from Venus. Serve is still a little concerning though. She has that strapping on one knee - not sure how much of a problem that is, or will prove to be.

Venus 2, Serena 2: The first decent rally is won by Serena, then she pulls out the first ace before a rather tame forehand into the net. But she hits back with a second ace to take the game and level up.
