Women's world No. 1 Iga Swiatek continued her unstoppable form this season by picking up a 30th successive win at the French Open Thursday.
Meanwhile, in the men's competition, 2021 runner-up Stefanos Tsitsipas survived yet another Roland Garros rollercoaster.
Swiatek swept past Alison Riske of the United States 6-0, 6-2 to reach the third round as only three of the top 10 women's seeds survived the opening two rounds.
Eighth-seeded Karolina Pliskova and Danielle Collins, the ninth seed, joined fellow top 10 players, defending champion Barbora Krejcikova, Maria Sakkari, Ons Jabeur, Anett Kontaveit and former winner Garbine Muguruza in failing to reach the last 32.
Swiatek, the 2020 champion in Paris, is on the best streak since Serena Williams's 34-match winning run in 2013 and goes on to face Danka Kovinic of Montenegro for a place in the last 16.
Swiatek raced through the first set against 43rd-ranked Riske in just 21 minutes and was 3-0 up in the second before the American avoided a "double bagel."
The Pole still managed to take her record of 6-0 sets in 2022 to a season-leading 15.
"I'm pretty happy to play some solid tennis," said Swiatek who joins third seed Paula Badosa and seventh-seeded Aryna Sabalenka in the last 32.
Fourth seed Tsitsipas needed another epic performance to reach the third round, beating world No. 134 and qualifier Zdenek Kolar of the Czech Republic.
The Greek star saved four set points in the fourth set tiebreaker to win 6-3, 7-6 (10/8), 6-7 (3/7), 7-6 (9/7) in a little over four hours.
On Tuesday, Tsitsipas had to come back from two sets down to defeat Lorenzo Musetti in the first round.
Kolar, 25, was playing in his maiden Grand Slam having tried and failed 16 times to qualify.
Tsitsipas will face Sweden's Mikael Ymer for a place in the last 16.
"He drove me crazy," said Tsitsipas. "It was really frustrating because he got behind every ball."
Pliskova was knocked out by French world No. 227 Leolia Jeanjean while Collins fell to American compatriot Shelby Rogers 6-4, 6-3.
Pliskova, a semifinalist in Paris in 2017, lost 6-2, 6-2 to 26-year-old Jeanjean.
Jeanjean is the lowest-ranked woman to beat a top 10 player at Roland Garros in 34 years.
Considered a future star at 12, she saw her career abruptly halted by injuries, including a triple dislocation of the knee.
She then left to study in the United States, only returning to top-level tennis at the end of 2020.
"I wanted to come back so as not to regret anything. I think I made the right choice," she said.
Pliskova has made the second week at Roland Garros just once in 11 visits.
Jeanjean will next face Romania's Irina-Camelia Begu who was fortunate not to be defaulted in her 6-7 (3/7), 6-3, 6-4 win over 30th seed Ekaterina Alexandrova.
Begu, in frustration, bounced a racquet into the crowd which then hit a child who burst into tears.
The supervisor was called but the 31-year-old escaped with a warning.
"It was embarrassing and I apologize," said Begu.
World number three Badosa overcame a scare to defeat 68th-ranked Kaja Juvan of Slovenia 7-5, 3-6, 6-2.
Spain's Badosa, a quarterfinalist in 2021, recovered from a breakdown in the decider to set up a meeting with 29th seed Veronika Kudermetova.
New York-born Badosa has endured a mediocre clay-court season with a semi-final run in Stuttgart but early exits at the elite events in Madrid and Rome.
"That competitive streak that I had lost in recent weeks has come back," she warned.
Simona Halep, the 2018 champion, fell to big-serving Chinese teenager Zheng Qinwen, playing just her second Slam, 2-6, 6-2, 6-1.
Halep admitted after the match that she had suffered a panic attack at the end of the first set. Sabalenka saw off Madison Brengle 6-1, 6-3.
Daniil Medvedev, the men's second seed, had few problems in making the third round with a 6-3, 6-4, 6-3 win over Laslo Djere of Serbia.
Medvedev, who made the quarter-finals in 2021, goes on to face another Serb in Miomir Kecmanovic, the 28th seed.
Djere hit 39 winners Thursday but was undone by 68 unforced errors.
Danish teenager Holger Rune reached his first Slam third round with a 6-2, 6-3, 6-3 win over Switzerland's Henri Laaksonen.
The 19-year-old fired 28 winners and managed to avoid a worrying injury when his foot became lodged in a tarpaulin cover on Court 12.
