Marin Cilic rolls into fourth round along with Juan Martin del Potro

Marin Cilic, Juan Martin del Potro and John Isner all reached the fourth round of the French Open.

Third seed Cilic blew away American Steve Johnson 6-3, 6-2, 6-4 to set up a last-16 encounter against Fabio Fognini.

The Czech broke once in the first set, twice in the second and one more time in the third to secure his place in the next round.

“Everything felt quite good,” Cilic said after the match. “[My] movement and serving was great, [it was] very consistent serving… I felt that I was controlling most of the points.”

Del Potro also had a relatively easy match as he secured a 7-5, 6-4, 6-1 victory over Albert Ramos-Vinolas from Spain.

“After the first set, I took the control of the game. I played [at a] high level most of the match,” the Argentine said. “It was a tougher first set for both, but I did well in just a couple of points, very important moments. And then I played much better.

“I felt good on court, and my movements were okay for today, so I’m glad for that.”

Next up for Del Potro is Isner after the American secured a 7-6, (7-1), 6-4, 7-6 (7-4) win over Pierre Hugues-Herbert from France.

Hugues-Herbert’s compatriot Gael Monfils also went down in five sets to David Goffin with the eighth seed winning 6-7 (6-8), 6-3, 4-6, 7-5, 6-3.
