PARIS — A minor car crash couldn’t sidetrack Coco Gauff before she began her French Open title defense.

It took a player who could match the American’s court coverage in long baseline rallies to mark the end of the road for Gauff in Paris.

That player was Anastasia Potapova, who produced a 4-6, 7-6 (1), 6-4 victory over Gauff in the third round Saturday.

“She was able to finish the points, and I wasn’t,” Gauff said. “Just not capitalizing on certain shots.”

The match was played before mostly empty stands inside Court Philippe-Chatrier as French fans stayed away to watch the Champions League soccer final between Paris Saint-Germain and Arsenal.

Gauff’s second Grand Slam title came with a victory over top-ranked Aryna Sabalenka in the final at Roland Garros a year ago.

Before her opening victory over Taylor Townsend on Tuesday, Gauff was involved in a car accident on the way to the tournament grounds. She wasn’t injured, but the car wasn’t drivable anymore.

The 30th-ranked Potapova, who was born in Russia but now represents Austria, improved to 3-2 in her career against Gauff. She’s having quite a clay season after reaching a final in Linz, Austria, and the semifinals of the Madrid Open as a qualifier.

The fourth-ranked Gauff was coming off a run to the Italian Open final. She was beaten in Rome by Elina Svitolina, another player who can match her on long rallies.

“I lost the same way in Rome as I did here,” Gauff said. “You never want to lose the same way back-to-back times.”

When Gauff shanked a forehand wide on Potapova’s first match point, Potapova fell on her back and covered her eyes as she stuck her feet up in the air in celebration. Gauff waved to the crowd and quickly walked off court when it was finished.

“Coco is such a champion. I respect her so much,” Potapova said. “I’ve been fighting for the last point, and here I am.”

Earlier, Naomi Osaka beat 18-year-old American opponent Iva Jovic, 7-6 (5), 6-7 (3), 6-4, after nearly three hours — in her 100th Grand Slam match — to set up a round-of-16 meeting with top-ranked Aryna Sabalenka.

Sabalenka beat Daria Kasatkina, 6-0, 7-5.

For the seventh straight day of the tournament, it was hot and humid, with the temperature rising to 93 degrees. The heat is expected to break for Sunday and the second week.

In men’s action, Alejandro Tabilo ended the run of 17-year-old Frenchman Moise Kouame with a 4-6, 6-3, 6-4, 7-6 (9) victory.

Juan Manuel Cerundolo followed up his stunning victory over top-ranked Jannik Sinner with another five-set victory, beating Martin Landaluce, 6-4, 6-7 (7), 7-6 (4), 6-7 (4), 7-6 (8) in 5 hours, 58 minutes, the longest French Open match in six years.

Cerundolo will meet 2021 Wimbledon finalist Matteo Berrettini, who required 5 hours, 13 minutes to defeat Francisco Comesana, 7-6 (3), 5-7, 6-7 (4), 6-4, 7-6 (13).

Flavio Cobolli beat Learner Tien, 6-2, 6-2, 6-3, and will meet unsung American Zachary Svajda, who defeated Francisco Cerundolo, 6-3, 6-4, 3-6, 4-6, 6-3, in the next round.

Later, Felix Auger-Aliassime plays American opponent Brandon Nakashima. At No. 4, Auger-Aliassime is the highest-seeded player remaining in the top half of the draw after Sinner’s defeat.
