Defending champion Rafael Nadal got his bid for a record-extending 12th French Open title off to the perfect start by brushing aside German qualifier Yannick Hanfmann, while world number one Novak Djokovic was also a comfortable victor in the first round at Roland Garros on Monday.
Nadal, a 17-time Grand Slam champion, cruised to a 6-2, 6-1, 6-3 victory on the rebuilt Court Philippe Chatrier to set up a clash with another German qualifier - world number 114 Yannick Maden - in round two.
Nadal had suffered three consecutive semi-final defeats earlier in the clay-court season, but appeared to find his best in an Italian Open title success sealed with victory over old rival Djokovic, while his French Open win-loss record now reads 87-2. "It's always amazing to play here, the new Chatrier is very nice," the second seed said. "It's been an important place in my career.
The 32-year-old Nadal raced into a 3-0 lead in the opening set before a second break of serve in the eighth game sealed it after just 40 minutes.
The second set was over in a flash as Nadal crushed nine winners past his beleaguered opponent.
The winning line honed into view when Nadal broke after a lengthy game to take a 2-1 advantage in the third, and the Spaniard completed the job on his first match point as world number 184 Hanfmann blasted long.
Djokovic laid down an early marker in his bid to hold all four Grand Slam titles simultaneously for the second time, powering past Polish youngster Hubert Hurkacz.
The 15-time major champion impressed in a 6-4, 6-2, 6-2 triumph and will face Swiss lucky loser Henri Laaksonen in round two.
Earlier on Monday, former world number one Caroline Wozniacki collapsed to a 0-6, 6-3, 6-3 loss to Russian world number 68 Veronika Kudermetova in the first round.
The Danish 13th seed had retired injured from her two previous matches in the lead-up to Roland Garros, and fell away badly after a strong first set.
"I think she got very lucky at the start of the second set and took advantage of the opportunities she got," said Wozniacki.
Sixth seed and two-time Wimbledon champion Petra Kvitova was forced to pull out before her scheduled opener against Sorana Cirstea with a left arm injury, but said she should be fit for Wimbledon, which starts on July 1.
Dutch fourth seed Kiki Bertens looked in fine fettle, though, beating home player Pauline Parmentier 6-3, 6-4.
