4-6 - ZVONAREVA WINS!! - She shows signs of nerves early in the game as she goes 0-30 down but then races into a 40-30 advantage. On the match point one of her shots is called out - she challenges - the replay shows it was in. They replay the point and she takes it with an overhead shot at the net. Only her second ever win over Petrova in six attempts and she is now in the quarter-finals for the first time and faces Marion Bartoli next.
4-5 - Petrova has to win a long rally to save the first match point of the match - Zvonareva eventually firing into the net - however, now the younger Russian has a chance to serve for the match.
3-5 - Big serve from Zvonareva sees her move one game away with a hold to 30. She was 40-0 in front but Petrova started hitting back so it was timely shot.
3-4 - Quick hold to 15 by Petrova keeps the pressure on.
2-4 - Two double faults from Zvonareva means she has to survive a deuce but no worse as she moves to within two games of victory.
2-3 - Petrova matches Zvonareva with a hold to love as servers enjoy a spell on top. Zvonareva has they key break advantage though.
1-3 - Zvonareva with a hold to love again though as she continues to boss on her own serve - she is hitting some sweet winners now too.
1-2 - Much better game from Petrova - more aggressive, purposeful and proactive - again she had to go to deuce before winning it but she looked more like her old self there.
0-2 - And she follows it with a hold to 15 capped off with a great forehand into the corner - Petrova already looking a bit like a beaten woman.
0-1 - Zvonareva has taken control of things now as she opens up the second set with a break.
5-7 - Great forehand from Zvonareva into the corner wraps up a hold to 30 and clinches her first set against Petrova for five years. Messy set from Petrova (30 unforced errors is the final tally) and she rushes out of the court to gather her thoughts.
5-6 - Petrova gives up yet another break point but this time there is no respite as she double faults. Petrova now has an amazing 28 unforced errors. Zvonareva has 16 herself which shows that this not exactly high quality stuff.
5-5 - Zvonareva ends Petrova's run of three games in a row with an accomplished hold to love.
5-4 - Really good hold from Petrova as she again comes back from 0-30 down - why must she make it so hard for herself though? The highlight of the game was on 30-30 when Petrova showed amazingly soft hands at the net to guide a little drop volley over.
4-4 - Very good returning from Petrova helps her to earn two breaks points. Zvonareva of course is 1/15 with break points but Petrova only needed one as Zvonareva went long with a poor shot at the middle of the court. Wasnt called out though and Petrova needed to challenge to get justice.
3-4 - Petrova goes 0-15 down and you say to yourself "here we go again" but she gets back to 15-15 and then produces three unreturnable serves in a row.
2-4 - Petrova forced back on to serve very quickly as Zvonareva holds to 15. The younger Russian dominating - it is hard to see how she hasn't even taken A SET against Petrova in their last four meetings.
2-3 - History repeats itself again - Petrova finds herself 0-40 down just like in the first game before producing three great serves to level. The pair then play NINE deuces and Petrova has to save another three break points but she does it! Zvonareva still a break up but just one - she has had 15 break points already today.
1-3 - Zvonareva wraps up another hold to 30 with an ace. Petrova is finding it hard to cope when the rallies develop because of the power that Zvonareva has in her shots.
1-2 - No such luck for Petrova in her second service game. She went 0-40 down and while she managed to save the first point she is finally broken. Zvonareva showing a lot more power in these opening stages.
1-1 - Much easier for Zvonareva - she opens with a hold to 15.
1-0 - Petrova wins a marathon open serving game where she had to save SIX break points. To be fair she played superbly well on the break points - great serving - Zvonraeva never had a clear chance to break but why could Petrova not play like that on the other points?
0-0 - Here we go Petrova serving in this opening game.
- - Petrova owns the head-to-heads - she has a 5-1 record and won the last time they met in LA last year.
