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.
