PARIS – Defending champion and fourth seed Garbine Muguruza reached the French Open fourth round with a 7-5, 6-2 win over Kazakh 27th seed Yulia Putintseva on Friday.

Spanish 23-year-old Muguruza will face either French 13th seed Kiki Mladenovic or unseeded Shelby Rogers of the United States for a place in the quarter-finals.

Muguruza's match on Friday featured 11 breaks of serve in the 20 games played.

Meanwhile, Canadian fifth seed Milos Raonic also advanced last 16 on Friday when veteran Spaniard Guillermo Garcia-Lopez retired through injury in the second set.

Raonic was leading 6-1, 1-0 when 153rd-ranked Garcia-Lopez quit after just 28 minutes of their third round encounter.

The world number six will meet either Grigor Dimitrov or Pablo Carreno Busta for a spot in the quarter-finals.

Belgian David Goffin was also forced to retire from his round match through injury.

The 10th seed damaged his ankle when he got caught up in court covers.

Goffin was leading Argentina's Horacio Zeballos 5-4 when he chased down the ball towards the back of the Suzanne Lenglen court.

However, his right foot got horribly jammed beneath the rolled-up covers before he tumbled into the wall and a linesman's chair.

Goffin, 26, was helped from the court by two officials and retired in the locker room.

Zeballos, the world number 65, has now reached the last 16 of a Slam for the first time where he will play either Austrian sixth seed Dominic Thiem or Steve Johnson, the 25th-seeded American
