Zverev has Nishikori's number
Three strikes and you're out. Zverev completed a trio of clay-court victories over Nishikori that started in Madrid, where the German topped the Japanese in straight sets en route to his 15th career title.
In Rome, one week later, the contest was closer, but Zverev still advanced in three sets.
Today in Paris, it was simply no contest. Zverev pushes his career record to 5-1 against Nishikori and records his fourth consecutive victory over the former world No.4.
"He served well, with these conditions, and he was hitting the ball pretty solid," said Nishikori. "I think today he was too good for me."
It wasn't for lack of trying for Nishikori.
Zverev's menacing game was just too hot to handle for much of the contest. The 24-year-old German was on the front foot all evening, playing first-strike tennis whenever he got the opportunity.
Remarkably, he won 60/90 of the points that lasted four strokes or less. Zverev cracked 25 winners, including five aces, and only hit two double-faults.
"Today I knew that I had to take Kei's racquet out of his hands, and be as aggressive as I could be," Zverev said. "At the end of the day I'm happy that I'm through, I'm happy with how I played."
