Stan Wawrinka @ $1.14 – Stan got a big wake up call in the first round and was far better in his second round match. I expect his form to continue to improve and he should be too strong for Viktor Troicki.
Angelique Kerber @ $1.14 – Kerber should have too much class for 58th ranked Kristýna Plíšková.
Venus Williams @ $1.36 – Venus looked very good yesterday and the veteran should account for 87th ranked Duan Yingying.
Worth a Punt
Jack Sock @ $2.31 – Sock has looked good in his first two matches and is in great form at the moment. Tsonga will have to play some good tennis to get the job done and I think Sock is a sneaky chance here.
Tomáš Berdych @ $2.34 – Federer has looked a little rusty in his first two matches and will need to be on his game to beat Berdych. Federer probably only just the favourite in my book and Berdych looks decent value in what should be a very even matchup.
Coco Vandeweghe @ $2.33 – Danger game for Canadian Eugenie Bouchard. Vandeweghe has a very powerful game and if she is in form, could be too strong for Bouchard.
