American teen Gauff yet to drop a set over opening 3 rounds

Coco Gauff reached the fourth round at the French Open by beating Kaia Kanepi.

The 18-year-old Gauff, the youngest remaining woman in the draw, defeated the 36-year-old Kanepi, the oldest remaining woman, 6-3, 6-4.

The young American is trying to improve on her quarterfinal run at Roland Garros a year ago.

Gauff had six aces — and five double-faults — while her Estonian opponent made 29 unforced errors. The teenager has not dropped a set in her first three matches.
