I don't see Stosur losing to Suarez Navarro on grass so I think she wins at least one. I don't know if Vandeweghe has got it in her to beat Errani either being that she wasn't exactly convincing against people like Kathrin Woerle or Arruabarrena-Vecino in qualies. I wouldn't be surprised if the Woz was the first one out. Not because I think she's the worst player in the world or anything but just because Paszek is quite a tough ask on grass, especially coming off her win in Eastbourne.
