Agnieszka Radwanska wins WTA Finals title

SINGAPORE (AP) — Agnieszka Radwanska beat fourth-seeded Petra Kvitova 6-2, 4-6, 6-3 Sunday at the WTA Finals to clinch the biggest title of her career.

The fifth-seeded Pole's previous best result at the season-ending championship was a semifinal finish — in 2012 and 2014.

Radwanska is the first player to win the tournament after a losing 1-2 record in the round-robin stage.

Radwanska led by a set and 3-1 in the second before Kvitova settled into the match to win seven of the next eight games.

The Czech led 2-0 in the deciding set, before Radwanska fought back to 3-3 and then won the last three games.
