Sam Stosur came from a set down to beat Canadian teenager Eugenie Bouchard 3-6 7-5 6-2 and claim the WTA Japan Open title in Osaka.
The former US Open champion claimed a second title of 2013 with her second Japan Open title - adding to the one she secured back in 2009.
Stosur sent down three aces in the match at the Utsubo Tennis Center and eventually wore down her 19-year-old opponent to win in two hours and 13 minutes.
Bouchard started well, breaking the Australian three times in a dominant opening set, and the second was a real struggle until Stosur managed to grab a break at 5-5 when it looked like heading to a tiebreaker.
After Bouchard had held serve to start the final set, Stosur got on a roll and won the next four games on the spin to open up a commanding advantage she would never relinquish.
"Eugenie was playing really well today. I just had to stick it out in the second set, and I'm pretty happy with how things went in the third," Stosur said.
"I love playing here. I love the site and the fans are great - I always feel like I have lots and lots of support when I come to Osaka."
A fifth career title for world No 20 Stosur saw her win twice in a season for the first time, after she also claimed the title in Carlsbad in August in her only other final appearance of 2013.
