Britain's Heather Watson has beaten Chang Kai-Chen (Taiwan) 7-5 5-7 7-6(4) in the Japan Open Women's Singles Final.
Heather became the first Briton to win a WTA Tour singles title in 24 years by winning a marathon match.
She beat Kai-chen of Chinese Taipei in the final of the HP Open in Osaka.
The 20-year-old from Guernsey looked to have thrown her way her chance of victory.
Having served for the match at 5-3 in the second set, she fell a break down and faced match point in the decider.
But she broke back before finally clinching a win in three hours 11 minutes.
Watson has followed in the footsteps of Sara Gomer, the last British winner of a singles title on the WTA Tour in California in 1988.
