Polish teenager Agnieszka Radwanska defied Jill Craybas' gallant fightback to win the Pattaya Open in Thailand.
Radwanska came through a tough test to win the title
The 18-year-old top seed eased through the first set but seventh seed Craybas hit back quickly to take the second.
Radwanska stormed into a 5-1 lead in the decider, only for the American to fight back and save two championship points and then surge 6-5 ahead.
But Radwanska triumphed in a tense tie-breaker to take her second career title with a 6-2 1-6 7-6 (7-4) victory.
"She came back, she was fighting to the last point, I could have finished the match twice, but I didn't. I was nervous and everything put me off," said the world number 21.
"It was a very strange match, but the most important thing is I won the match.
"I was very surprised, the first and second sets were over quickly, the third set should have been easy for me but it wasn't."
Craybas, 33, who has not won a title in almost six years, thought she was going to end her title drought.
"I thought the win was mine at 5-5 -- definitely. I'd visualised winning. I could have been more aggressive at match point.
"I just kept playing my game, she got a little nervous towards the end. I'm disappointed I lost. I fought my hardest, and I know I gave 100%."
