Dominic Thiem has reached the fourth round of the French Open after dominating Casper Ruud in straight sets.
The US Open champion who has yet to drop a set at Roland Garros recovered from a slow start to beat the Norwegian 6-4, 6-3 and 6-1.
Thiem did not seem to be at his best after trailing 3-1 in the opener and was under pressure in nearly all his service games. But he gradually took command to secure the victory with his fifth ace.
The Austrian will next face Hugo Gaston who managed to upset former French Open champion three sets to two.
