Defending champion Rafael Nadal beat Jannik Sinner 7-5, 6-3, 6-0 to reach the quarterfinals and extend his streak of sets won at Roland Garros to 35.
The 18th-seeded Sinner had a chance to become the first player since Dominic Thiem in the 2019 final to take a set off Nadal here.
But when serving for the first set at 5-4, the Italian was broken at love. He then lost the next six games to trail 4-0 in the second set.
Thiem took the second set 7-5 to level the 2019 final.
Nadal won the next two sets to clinch his 12th title here, won all 21 sets last year as he added No. 13 and has yet to drop a set this year.
The third-seeded Spaniard faces No. 10 Diego Schwartzman in the quarterfinals, having beaten the Argentine in the semifinals last year.
