WTA Dubai Betting: Erratic Errani to finally meet her match in Petrova

Sofia Arvidsson's deciding loss in Memphis was disappointing on Wednesday night after Petra Kvitova had got the day off to a good start in Dubai.

The Swede's defeat to Marina Erakovic cost me my double after Kvitova had defeated Ana Ivanovic in the opening leg.

The withdrawal of Serena Williams from the Dubai tournament meant that the event had lost its top two seeds, without either of them hitting a ball. The draw is now wide open on quarter-finals day.

Roberta Vinci takes on Sam Stosur first up and the Italian certainly has a good chance in that one at a price of around 2.28, based on the form she's showed against Sveta Kuznetsova and Angelique Kerber so far.

Following that, it's Nadezda Petrova against Sara Errani and surely this should be end of the road for the diminutive Italian, who is struggling with injury.

Errani has been fortunate to have played two opponents who have beaten themselves so far this week and assuming Petrova is fit, which is never a given with the Russian, she should have too much in these conditions for Errani.

They met twice last season, with Errani winning on the slower hard of Melbourne and Petrova prevailing in faster conditions in Tokyo. If she can keep the error count down, Petrova should take this at around 1.70.

The night session begins with Caroline Wozniacki taking on Marion Bartoli and I would expect the Dane to come through there, but Kvitova has a puncher's chance against defending champion Aga Radwanska at a tempting 2.30.

This match is all about Kvitova's radar. If it's on she could win this fairly comfortably and if it isn't, she'll lose. Pretty straightforward and simplistic, but in these fast conditions Kvitova's winner to error count will decide this, against the much more solid and crafty Radwanska.

Best Bet: Back Petrova to beat Errani at 1.70
