Alexander Zverev hits a forehand against Kei Nishikori during their French Open fourth-round clash in Paris on Sunday.
Alexander Zverev has reached his third French Open quarterfinal by eliminating Kei Nishikori 6-4, 6-1, 6-1.
The No. 6-seeded Zverev is seeking his first Grand Slam title. He was the runner-up at last year's US Open.

Up next for Zverev, a 24-year-old from Germany, is a match Tuesday against unseeded Alejandro Davidovich Fokina of Spain.
Nishikori was a U.S. Open finalist in 2014 and has been ranked as high as No. 4. But he's now lost 10 matches in a row against Top 10 opponents.
Alejandro Davidovich Fokina reached his first Grand Slam quarterfinal with a 6-4, 6-4, 4-6, 6-4 victory over Federico Delbonis at Roland Garros.
The 22-year-old Davidovich Fokina is ranked 46th.
