American teenager Coco Gauff won her first WTA title by beating Jelena Ostapenko 6-3, 1-6, 6-2 to capture the Upper Austria Ladies on Sunday.

Gauff is the youngest American woman to win a tour singles title since 1991. Venus and Serena Williams were 17 when they won their first titles. Jennifer Capriati was younger than Gauff is now when she won her first title in 1991.

Gauff is set to become World No. 71 as a result of this win.

The 15-year-old Gauff, who reached the fourth round at Wimbledon and third round at the US Open, bounced back after losing a one-sided second set to win comfortably.
