"He's playing very good on clay". Both Grigor Dimitrov and David Goffin agreed that they loved the movement on clay, with Dimitrov saying "I think the best thing is sliding all over the place, I love that". Nadal has won nine of 11 career meetings to date, though Nishikori took the most recent matchup - the bronze medal match at the 2016 Rio de Janeiro Olympics. Three of the last four matches have been decided in straight sets Nadal is 3-0 against Nishikori on clay.
Nadal edged the opening set in the 10th game with a blistering forehand before he raced into a 5-0 lead in the second to stamp his authority on the match.
Djokovic has played at four tournaments this season as he tries to return to form following two years of struggles with a persistent right elbow injury.
The Japanese was strong on serve from the outset, making a single break in a lengthy fifth game before securing the first set as Cilic found the net with a backhand. He said his wrist remains a "little bit sore".
The former world number four, now ranked 36, did enough to wear down a exhausted Zverev who came through a late-night thriller with Richard Gasquet on his 21st birthday on Friday. He beat Nadal in their last encounter two years ago to take the bronze medal at the Olympic Games in Rio de Janeiro. "There's still going to come a day that I feel I can do that or beat him on that surface".
