Paris: Serena Williams made a slow but successful start on Monday to her latest pursuit of a record-equalling 24th Grand Slam title at Roland Garros while US Open winner Dominic Thiem navigated a testing first-round tie against former major champion Marin Cilic.
Playing later, Rafael Nadal got his bid for a 13th Roland Garros title off to a comfortable start with a 6-4, 6-4, 6-2 win over Egor Gerasimov of Belarus.
World number two Nadal can level Roger Federer’s record of 20 Slam titles with victory in Paris.
The 34-year-old will take on Mackenzie McDonald of the US for a place in the last 32.
Serena is chasing an elusive 24th Grand Slam title to match Margaret Court’s all-time mark, but clay is her least favoured surface.
An error-prone beginning from Williams left world number 102 Kristie Ahn serving for the first set before the three-time Roland Garros champion prevailed 7-6 (7/2), 6-0.
Williams, playing at the French Open for the 18th time, dropped serve twice as Ahn moved 5-4 ahead in the opener in a rematch of their first-round encounter at Flushing Meadows.
But the sixth seed forced a tie-break that she sealed with an ace after a 74-minute slog before charging to an ultimately comfortable victory.
“She played very well in the first set, it wasn’t easy for me and she hit a lot of winners,” said Williams. “It was important for me to stay focused.”
Williams, seeded sixth here, has not gone beyond the last 16 in Paris since her defeat to Garbine Muguruza in the 2016 final. Her last major came at the 2017 Australian Open while pregnant.
Meanwhile Thiem, the runner-up to Rafael Nadal in Paris the past two years, defeated 2014 US Open champion Cilic 6-4, 6-3, 6-3 in their second meeting at a major this month.
“My level was good. I was very happy with the way I played from the beginning to the end basically,” said Thiem.
Having captured his maiden Slam in New York, Thiem is trying to become the only man in the Open era to win his first two majors at successive tournaments. A steady display from Thiem saw the Austrian break Cilic six times under the roof of Court Philippe Chatrier on another gloomy day at Roland Garros, pushed back from its customary May-June slot due to the coronavirus pandemic.
“I really love this tournament, it’s by far my best Grand Slam tournament so far,” said Thiem, who plays American qualifier Jack Sock in the second round.
“I’m from Austria so I know how it is to play in these cold conditions. I love it when it’s not too fast. I felt well from the first moment I came here.”
HALEP, GAUFF ADVANCE: The competition began Sunday amid steady drizzle in temperatures struggling to reach 10 degrees (50F), conditions branded “ridiculous” by US Open finalist Victoria Azarenka.
On a grim day for Britain, ninth seed and 2019 semi-finalist Johanna Konta was knocked out by teenage sensation Coco Gauff having committed 41 unforced errors. The 16-year-old American, making her debut in the main draw having been the junior champion just two years ago, eased to a 6-3, 6-3 win despite serving up 12 double faults.
Top seed and 2018 champion Simona Halep swept into the second round with a 6-4, 6-0 victory over Spanish world number 70 Sara Sorribes Tormo.
Playing under the roof, second-ranked Halep trailed 4-2 but claimed the final 10 games to progress in 82 minutes.
“The perfect present was that I won today,” said Halep who was celebrating her 29th birthday.
Play on Monday was initially delayed by more persistent rain. Twice Wimbledon champion Petra Kvitova defeated Oceane Dodin 6-3, 7-5 in the only match to start on time under the new roof on Court Philippe Chatrier.
Dutch fifth seed Kiki Bertens recovered from a poor start once conditions improved to overhaul 112th-ranked Ukrainian Katarina Zavatska 2-6, 6-2, 6-0.
Third seed Elina Svitolina scrapped past Varvara Gracheva of Russia 7-6 (7/2), 6-4 while last year’s runner-up Marketa Vondrousova was bundled out 6-1, 6-2 by 2018 junior champion Iga Swiatek.
