Defending champion Coco ‌Gauff was sent spinning out of the French Open as Austria’s Anastasia Potapova ‌claimed a 4-6 7-6(1) 6-4 victory to reach the fourth round on Saturday and ​stay on course to win her maiden Grand Slam title.Potapova rattled Gauff with powerful baseline hitting and broke to love in the opening game, before taking ​a 4-2 lead when the American slipped and dropped to the floor of Court ⁠Philippe Chatrier while trying to reach for the ball.Gauff dusted ‌herself ‌off ​and won the next two games in front of a sparse centre court crowd, with the ⁠attention split between Paris ​Saint-Germain’s Champions League soccer final ​with Arsenal in Budapest and Frenchman Moise Kouame in action ‌at Roland Garros.The 22-year-old raised her ​game again to take the first set, but Russian-born Potapova ⁠immediately ramped up the pressure ⁠and targeted ​the American’s wobbly serve to grab a double break at the start of the second set.Potapova was on the verge of levelling the match while ahead 5-2 but Gauff moved through the gears to surge ahead by claiming four games in a row, only to lose the next ‌game and then ⁠the set in a tiebreak where her serve let her down.The pair traded breaks in a breathless decider, but ‌world number four Gauff lost her way as Potapova took control and went ​through in style for a meeting with 22nd ​seed Anna Kalinskaya in the fourth round.
