Holger Rune and Beatriz Haddad Maia triumphed in marathon French Open epics which took almost eight hours to complete while Iga Swiatek required just 31 minutes to move into the quarterfinals.

World No. 6 Rune reached a second successive quarterfinal in Paris with his first ever five-set win.

The 20-year-old Dane claimed a four-hour 7-6 (7/3), 3-6, 6-4, 1-6, 7-6 (10/7) victory over Francisco Cerundolo and will face 2022 runner-up Casper Ruud in a repeat of last year's bad-tempered quarterfinal.

Rune was jeered by the Court Philippe Chatrier crowd for hitting the ball on a double bounce in the fourth game of the third set.

His 23rd seeded Argentine opponent stopped playing, expecting the umpire to call the point for him.

Play continued and Cerundolo, who was called for hindrance when he halted, dropped serve.

"This is tennis. This is sports. Some umpires, they make mistakes. Some for me, some for him. That's life," Rune said.

Cerundolo, playing in the second week of a Slam for the first time, had the crowd on its feet when he hit back to level the match.

In a dramatic decider, Rune survived being 3-4, 0-40 to hold and then break.

He served for the match at 5-4 but the 24-year-old from Buenos Aires hit back to level for 5-5 and held for 6-5 before the match went to a knife-edge super-tiebreak.

Rune finished the match with 48 winners and 73 unforced errors.

"What a sport," Cerundolo tweeted.

Haddad Maia won the third longest ever women's match at Roland Garros to become the first Brazilian woman in the last eight of a Slam since 1968.
