Svitolina won their only previous meeting. That was in an ITF event in January 2013. She won in 2 sets on a hard court.
Konta has looked pretty comfortable in both her round robin matches. She beat Stosur and Garcia in straight sets.
Svitolina dropped the opening set against Bertens and their second set was close. Svitolina took it 6-4 and sailed through the deciding set. Vesnina was never really in their match and Svitolina served well, saving all 8 of the break points she faced.
This could be a decent match. Stats this year on all surfaces slightly favour Svitolina though Konta has a better win loss ratio. I can see this going to 3 sets and value is on Svitolina at the start. However I favour Konta to win in the end.
Back Konta if she is broken first.
