Garbine Muguruza has breezed through to the next round at the French Open.

The 24-year-old Spanish-Venezuelan tennis player and former World No. 1 lost her serve just once to Australian Samantha Stosur in a 6-0, 6-2 rout to reach the fourth round at Roland Garros.

Muguruza, the 2016 French Open champion and three-time semifinalist here, faced no break points in winning the first set in 26 minutes.

Facing three break points in the fourth game of the second set, she served a double fault, allowing Stosur to level at 2-2. But she then rattled off the next four games for the match.

Muguruza next faces 39th-ranked Lesia Tsurenko, who upset 19th-seeded Slovak Magdalena Rybarikova 6-2, 6-4.
