Upset of the previous day:
Catherine Bellis def. Dominika Cibulkova 6-1 4-6 6-4
I know Cibulkova isn't playing well, but to lose to someone ranked outside the top 1000 is just baffling. Bellis took advantage of Dominika's weak serve and made her look like the one who's ranked outside the top 1000. With this, she becomes the youngest player to win a Grand Slam match since Anna Kournikova. As for Cibulkova, she needs to take a break and find herself again.
Daniela Hantuchova vs. Alize Cornet
Daniela is defending quarter-finalist points here, but it's tough to see her reaching that stage. Cornet's scrambling game will make Hantuchova go for too much, and hit herself out of the tournament. Daniela's form has been dire for the past year, so I don't think she can surprise at the twilight years of her career.
Pick: Cornet in 2 sets
Belinda Bencic vs. Kurumi Nara
Promising star Belinda Bencic stands a good chance of upsetting Kurumi Nara, one of the weaker seeds in the draw. However, Kurumi has been improving a lot this year, and Bencic will have to play her best to topple the Japanese. The Swiss still has some maturing to do game-wise, so while I believe she will put up a good fight, the steadier Nara will still emerge victorious.
Pick: Nara in 3 sets
Mirjana Lucic-Baroni vs. Shahar Peer
One of these ladies will have a chance to appear in a 3rd round of a Grand Slam, which is a very nice surprise for these 2 aging players. It is arguable that the best years of these ladies are over, so the reward in the last 32 will be extra sweet. Mirjana can hit with the best players of the world, but she's just not consistent enough. Peer's game will make Lucic try outrageous shots, so the Israeli stands at an advantage here.
Pick: Peer in 3 sets
Sloane Stephens vs. Johanna Larsson
Sloane Stephens is playing well, but her opponent just destroyed Virginie Razzano with the dreaded double bagel in her first round. Can Larsson carry her good form here? Firstly, she will be daunted by the prospect of playing an American on the huge Arthur Ashe stadium. Besides, Larsson's game will always be limited by her weak backhand. Sloane will take full advantage of that side and cruise to a comfortable victory.
Pick: Stephens in 2 sets
Sure win bets: Caroline Wozniacki, Jelena Jankovic, Angelique Kerber, Simona Halep
Upset alert: Roberta Vinci, Andrea Petkovic
