Gauff overcomes erratic serve to win 1st-round match at French Open

American teenager Coco Gauff did not let 10 double-faults, 12 break points or a warning from the chair umpire about receiving coaching from Dad disrupt her progress into the second round at Roland Garros.

The 18-year-old Gauff began her trip to Paris with a 7-5, 6-0 victory over Canadian qualifier Rebecca Marino on Sunday.

Gauff’s best performance at any Grand Slam tournament came a year ago at the French Open, where she reached the quarterfinals before losing to eventual champion Barbora Krejcikova.

Gauff had some serving issues against Marino but managed to set aside 10 of the 12 break points she faced. One key stat that helped Gauff was that she made only 16 unforced errors, while Marino accumulated 40.

Marino was appearing in the French Open for the first time since 2011.
