In St. Petersburg, Donna Vekic pulled off a straight-set upset over Australian Open finalist Petra Kvitova. Both women put on a hot-shot show during a contested 6-4, 6-1 win for the Croatian.

Vekic is into the semifinals of the Premier event where she faces former world No. 2 Vera Zvonareva. Ranked No. 97 and the only unseeded player in the draw, Zvonareva is still on the comeback trail after having a daughter in 2016.
