TIANJIN, China (AP) Agnieszka Radwanska is one win away from sealing her spot at the WTA Finals after beating Karolina Pliskova 6-3, 6-1 to reach the final of the Tianjin Open on Saturday.

The second-seeded Pole will reach the WTA Finals in Singapore if she captures the Tianjin title.

Radwanska broke the third-seeded Pliskova's serve four times and saved both break points she faced to prevail in 66 minutes.

Kovinic is the first Montenegrin to reach the final of a WTA Tour event.
