World number three Coco Gauff reached the last 16 at the French Open for a fourth successive year on Friday with a straight sets win over Dayana Yastremska of Ukraine.
US Open champion Gauff, the runner-up to Iga Swiatek in Paris in 2022, came through an error-riddled clash on Court Philippe Chatrier 6-2, 6-4.
The 20-year-old American will face unseeded Elisabetta Cocciaretto of Italy for a place in the quarter-finals.
Gauff was 5-2 ahead in the second set before she eventually prevailed on a second match point after a clash where both players carved out 22 break points and combined for 62 unforced errors.
