Jannik Sinner ended the retiring Richard Gasquet's career with a one-sided victory at the French Open on Thursday, while Novak Djokovic successfully continued his Grand Slam record bid at Roland Garros.

Against Valentova, an 18-year-old who won the junior title at the French Open last year and was competing in the main draw at a major tournament for the first time, Gauff got broken five times. Four of those came in the second set — and each time, the 21-year-old Floridian managed to immediately rebound to claim Valentova’s very next service game.
