Match focus:

Venus Williams vs. Simona Halep

Venus Williams conquered the sick Azarenka and will be facing another tough test against Simona Halep. The Romanian will get many balls back and make Venus hit the winner. There are some good signs for the American, who moved beautifully and seemed energetic on court. Hopefully she can keep that form and play to her best against Halep. Now, we have to see if Venus can back up her win with another one against the in form Simona. It will be close, but I expect the slam champion to edge out a win.

Pick: Williams in 3 sets

Angelique Kerber vs. Ana Ivanovic

Kerber has been under the radar recently but she's cruising through the tournament with minimal fuss. She will face a tough test against the impressive Ivanovic, who has been dominant in her last 2 matches. One thing's for sure, Ana isn't going to be serving breadsticks and bagels to Kerber. The dogged German will run down every ball and make sure the Serbian earns her points. With her fickle mentality, you would expect Ana to break sooner or later. However, Kerber's form hasn't been too impressive either, so it's anyone's game. Still going to give Angelique the edge here.

Pick: Kerber in 3 sets

Madison Keys vs. Petra Kvitova

If there's anyone who has mastered the art of winning ugly, it's Petra Kvitova. The Czech hasn't had a straightforward win since the longest time, but always manages to rein it in when it matters. Against Keys, she will no doubt be challenged. But like always, she will make the shots when it matters and if things are going too well, she'll stink up the court for one set to make sure it goes the distance. Judging by her performance so far, Petra hasn't put in the necessary work ethic needed to be a number 1 player. However, if she's not bothered, why should we?

Pick: Kvitova in 3 sets

Sure win bets: Agnieszka Radwanska, Caroline Wozniacki, Jelena Jankovic
Upset alert: Simona Halep, Samantha Stosur, Sorana Cirstea
