Match focus:

Camila Giorgi vs. Marina Erakovic

With the lightnig fast surface, it's no wonder these 2 players have posted good results here. Out of these 2 players, I would say Giorgi has the more lethal game on the indoor surface. The Italian's flat serve and groundstrokes have been clicking so far, so it's difficult to get into a rhythm with her playing so well. Marina will need to disrupt Camila's rhythm by using slices and volleys to rush her. It won't be an easy task though, with the way Camila has been playing.

Pick: Giorgi in 2 tight sets

Luksika Kumkhum vs. Madison Keys

Madison Keys has won her first title this year, but has since regressed back into her erratic ways. The American has the game to be a solid top 20 player, but has to rein in her aggressive play at the right time. This probably wouldn't happen too often, but Keys is facing an opponent with an even more aggressive mindset than her. Kumkhum can wallop the ball as well as anybody, but her lack of a defensive game puts her at a disadvantage when she's pulled wide. Both players need plenty of maturing to do, but Keys should be the one who is more experienced in the big stage.

Pick: Keys in 2 sets

Zheng Saisai vs. Sorana Cirstea

With her huge upset over Jankovic, Zheng Saisai will need to focus immediately on another dangerous opponent in former top 20 player Cirstea. The Romanian has rekindled her fire recently, and will be the slight favourite here. Zheng will need to play a very steady and counter punching game against the hard hitting Sorana. If the Chinese can get the Romanian riled up, she can cause another upset. However, Zheng has the habit of faltering after a big win, so I expect Sorana to cruise.

Pick: Cirstea in 2 sets

Sure win bets: Belinda Bencic, Varvara Lepchenko, Samantha Stosur
Upset alert: Zarina Diyas
