AMERICAN 15-year-old phenom Coco Gauff won her first-ever WTA title Sunday, becoming the youngest champion in 15 years in the process.

Gauff took down Jelena Ostapenko 6-3, 1-6, 6-2 at the Linz Open in Austria, capping off an incredible start to her young career and an impressive tournament.

At 15 years and seven months old, Gauff is the ninth-youngest woman to ever win a title. She’s the youngest champion since Nicole Vaidisova (15 years, 3 months, 23 days) won at Vancouver in 2004.

Gauff rose to prominence this year when she made the fourth round of Wimbledon and third round of the U.S. Open, earning the respect of World No. 1 Naomi Osaka, but this was perhaps her best showing yet. Despite struggling through a tough second set, Gauff won the first five games of the final set to put the match out of reach.

Gauff only dropped two sets in her five matches of the tournament and knocked off world No. 8 Kiki Bertens in straight sets in the process.

That was her first win against a top-10 ranked player after losing her two previous chances against Osaka and Simona Halep.
