Earlier, sixth seed Andrey Rublev came through a tough test against Taro Daniel to reach the second round.
Russia’s Rublev did not have it all his own way on Court Simonne-Mathieu but worked his way to a 6-2 6-7 (3-7) 6-3 7-5 win over Japan’s Daniel.
The 26-year-old is looking to go beyond the quarter-finals of a Grand Slam for the first time.
Rublev has struggled with his on-court demeanour over the years and threw his racquet to the ground in frustration after missing three set points in the second set.
However, he showed determination to regroup and grind out victory in three hours and 11 minutes, despite world number 80 Daniel almost forcing a fourth-set tie-break.
Rublev will face Pedro Martinez next after the Spaniard needed five sets to claim a 5-7 6-4 3-6 6-4 6-3 victory over Thiago Agustin Tirante of Argentina.
Poland’s eighth seed Hubert Hurkacz also went the distance in his match against Japanese qualifier Shintaro Mochizuki, eventually winning 4-6 6-3 3-6 6-0 6-3.
Earlier, French number one and 17th seed Ugo Humbert lost 6-4 2-6 6-4 6-3 to Lorenzo Sonego of Italy, while Bulgarian 10th seed Grigor Dimitrov defeated American Aleksandar Kovacevic in straight sets.
Three-time Japanese quarter-finalist Kei Nishikori went the distance in his 7-5 7-6 (7-3) 3-6 1-6 7-5 win over Canadian qualifier Gabriel Diallo, and American 27th seed Sebastian Korda beat French wildcard Harold Mayot in straight sets.
