Holger Rune and Beatriz Haddad Maia triumphed in marathon French Open epics which took almost eight hours to complete on Monday while Iga Swiatek required just 31 minutes to move into the quarter-finals.
World number six Rune reached a second successive quarter-final 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 against Francisco Cerundolo and will face 2022 runner-up Casper Ruud in a repeat of last year's bad-tempered quarter-final.
