PARIS (AP) — After the French Open marathon came the sprints.

Defending champion Iga Swiatek swept into the quarterfinals at Roland Garros in just 40 minutes after a crushing 6-0, 6-0 win against Anastasia Potapova.

U.S. Open champion Coco Gauff took only 60 minutes to rout unseeded Italian Elisabetta Cocciaretto 6-1, 6-2.

The 20-year-old American looked set for an even quicker victory when she led 5-0, but Cocciaretto fought back, getting a hearty cheer from the crowd after winning the next game.

Swiatek wound up with 48 points to just 10 for Potapova. The match ended when Potapova hit a forehand into the net on the first match point.

“I was just really focused and in the zone,” Swiatek said. “It went pretty quickly, pretty weird.”

Their match started at around 11 a.m. on Court Philippe Chatrier.

That’s just eight hours after men’s defending champion Novak Djokovic finished his five-set, 4 1/2-hour marathon against Lorenzo Musetti just after 3 a.m. in the latest finish in tournament history.
