France's Caroline Garcia fought back to beat Australian Ashleigh Barty and win the biggest title of her career at the Wuhan Open in China.
Garcia, ranked 20th in the world, won the final - between two unseeded players - 6-7 (3-7) 7-6 (7-4) 6-2 to claim her fourth title.
World number 37 Barty served for the match twice but could not seal a fifth win of the week over a top-20 player.
"It was a such a fight all the week and especially today," said Garcia, 23.
"To win a title, it's always something very special. Premier 5, it's even better. You can't let it go, you have to fight until the end. That's why you train hard, to play these kind of moments."
Barty, 21, could not cap a remarkable week with the trophy, having seen off top-10 seeds Karolina Pliskova, Johanna Konta and Agnieszka Radwanska in the earlier rounds.
The Australian only chose to return to tennis last year after an 18-month break, during which she played for Brisbane Heat in cricket's Big Bash League.
"I put myself in a position where I could win the match, and tonight I couldn't finish it off, which is disappointing," said Barty.
"For us, still a hell of a week, probably the best week of my tennis career. So, yeah, we move on and we live and learn."
