Agnieszka Radwanska won the biggest title of her career on Sunday as she downed two-time Wimbledon champion Petra Kvitova 6-2, 4-6, 6-3 to win the WTA Finals in Singapore.

Radwanska, who lost twice at the round-robin stage and upset Garbine Muguruza in the semis, came from a break down in the deciding set to win a tense final in two hours and five minutes.

The 26-year-old Pole, who was a last-minute qualifier for the eight-player season finale, was in tears after winning the prestigious title at her seventh attempt.

"It just means everything—it was my first final and it couldn't have been any better," she said.

Radwanska dominated the first set but Kvitova hit back to win the second and take it to a decider at an increasingly tense Singapore Indoor Stadium.

The Pole went down a break early in the third but she snatched back control and saw off a gritty fightback by Kvitova, who was hampered by an injury to her heavily strapped right leg.
