American teenager Coco Gauff rocked by shocking stat in French Open debut

American teenager Coco Gauff's French Open debut has ended in the second round after she double-faulted 19 times in a 4-6, 6-2, 7-5 loss to 159th-ranked qualifier Martina Trevisan.

Gauff, ranked world No.51, double-faulted twice in the last game of the 2-hour, 11-minute match.

The 16-year-old Gauff has reached at least the third round at the other three major tournaments.

For Trevisan, a 26-year-old from Italy, this was her first victory in a grand slam match played to its conclusion.

She lost in the first round at the Australian Open this year in her first appearance at a major, then advanced Sunday at Roland Garros when her opponent, Camila Giorgio, stopped playing in the second set because of an injury.

Against Gauff, Trevisan kept yelling, "Yes!" and "Let's go!" in Italian between points, then let out a high-pitched scream when the match ended.
