Sloane Stephens sees off Muchova to reach French Open fourth round

American finds form in beating 18th seed 6-3, 7-5
Defending champion Iga Swiatek also through

There are few players who possess the skill and athleticism that Sloane Stephens imbues her matches with at the height of her powers. She is arguably the best mover on tour, particularly on clay, with one of the heaviest forehands and a vast toolbox of shots.

But Stephens is also maddeningly streaky, so one of the great sights of the French Open so far has been her long-awaited resurgence. Stephens continued her rise by outplaying the 18th seed, Karolina Muchova, 6-3, 7-5 to reach the fourth round for the seventh time.
