Agnieszka Radwanska won the WTA Championships in Singapore when she beat Petra Kvitova in the final on Sunday.
The fifth-seeded Pole won in three sets, in a match lasting two hours and six minutes by beating the Czech sixth seed 6-2, 4-6, 6-3.
Radwanska started very well to break two-time Wimbledon winner Kvitova and in the fifth game she broke again to lead 4-1 and went on to win the set 6-2.
The Pole never let up in the second set and broke serve early to race to a 3-1 lead and what looked like heading to a straight sets victory.
However, Kvitova came fighting back to break and eventually lead 4-3.
Radwanska held serve to make the score 4-4 but Kvitova was playing well and her shots were finding their range, she eventually went on to clinch the set and force a decider.
In the third set, there were four breaks of serve in the opening six games but when Radwanska went 4-3 up she then held serve to be a game away from the win.
Radwanska sealed the win without too much trouble taking the first of the three championship points on offer to win the set and match 6-3.
