Agnieszka Radwanska secured her first WTA Tour title since January when she beat Anastasia Pavlyuchenkova at the Korean Open in Seoul.
However, the top-seeded Pole was fully tested as she needed two hours and 48 minutes to see off her Russian opponent 6-7 (8-6) 6-3 6-4.
The No 3 seed Pavlyuchenkova, who came from three-nil behind to win the opening set, edged through a tie-break which featured just a single break of serve.
But the 24-year-old Radwanska, whose most recent title success came in Sydney more than eight months ago, hit back to take the second set on her third set point - having broken Pavlyuchenkova's serve three times.
The final set was a particularly tight affair with Radwanska saving three break points from 0-40 down in the seventh game and then another one in the ninth.
And the stylish world No 4 from Krakow finally crossed the finishing line by claiming the only break of serve of the deciding set in game 10 when she clinched a hard fought win on her second match point.
Radwanska said: "It was a very close match, tight sets all of them, but I was just a little bit better in the important moments."
Pavlyuchenkova added: "It's tough losing this match after fighting so long and coming so close.
"It's difficult and frustrating but in tennis you can be up and then down."
All of Radwanska's three title successes during 2013 have come on hard court, while Pavlyuchenkova's run to the final should see the 22-year-old Moscow resident rise up the world rankings from her current position of 32.
The only other players to win three of more WTA titles this year are: Serena Williams (9), Simona Halep (4) and Victoria Azarenka (3).
