Romanian Simona Halep battled back from a set down to beat former U.S. Open champion Samantha Stosur 2-6 6-2 6-2 in a thrilling Tournament of Champions final on Sunday to capture her sixth title of the year.
Stosur began her 19th WTA final confidently and took the opening set with ease, surrendering just five points in the first four games with Halep struggling with a very low first-serve percentage.
But Halep, an aggressive baseliner, stepped up her game and broke three times in a row to win the second set with hard-hitting Stosur, the oldest player in the tournament, losing her rhythm.
Stosur, who had looked in blistering form in the semi-finals where she humbled Russia's Anastasia Pavlyuchenkova, continued to rely on powerful kick serves in the third set but Halep broke decisively in the 21st game and got the upper hand, winning the next three games.
Halep, who also beat Stosur in the Kremlin Cup final last month, wore down the 29-year-old Australian with some booming forehands into an open court after pushing her out wide with a number of clever shots.
Halep's triumph was cheered by hundreds of Romanian fans, including Ilie Nastase and the Balkan country's sports minister Nicolae Banicioiu, who made the 370-km trip to the Bulgarian capital.
The $750,000-tournament featured six highest-ranked players who have won at least one International Series title during the year and did not qualify for the more lucrative WTA Championships.
