SINGAPORE (AP) Defending champion Agnieszka Radwanska took the final spot in the semifinals of the WTA Finals, beating Karolina Pliskova 7-5, 6-3 on Friday.
Radwanska, who finished 2-1 in the round robin, will play top-seeded Angelique Kerber in Saturday's semifinals. Kerber won the Australian Open and the U.S. Open this season, and reached the Wimbledon final.
"I think I really have nothing to lose at the moment, especially (since) I'm going to play the best player of the season," Radwanska said of the top-ranked German. "She's played incredible tennis this year."
