Croatian Marin Cilic did not put a foot wrong as he crushed Russia's world number two Daniil Medvedev 6-2 6-3 6-2 in a lopsided contest on Monday to return to the French Open quarter-finals after a gap of four years.
The 2014 U.S. Open champion, seeded 20th, dominated proceedings from the start and finished off the contest in an hour and 45 minutes to reach the last eight stage on the Parisian clay for the third time in his career.
Medvedev came into the match having won all three previous meetings against the 33-year-old Croatian but cut a sorry figure under the lights on Court Philippe Chatrier in their first contest on clay.
"It was absolutely a fantastic match from the first point to the last," Cilic said in his interview on court.
"I enjoyed the atmosphere, enjoyed the night session here, played incredible tennis, one of the best matches of my career from start to finish."
Such was the Croatian's domination that he did not face a break point and will next meet another Russian in seventh seed Andrey Rublev for a place in the semi-finals.
Teenage sensation Holger Rune outmuscled world number four and last-year's French Open finalist Stefanos Tsitsipas 7-5 3-6 6-3 6-4 to move into the quarter-finals with his biggest Grand Slam win to date.
The Dane, who has improved more than 350 places in the world rankings in the past 15 months, joins fellow 19-year-old Carlos Alcaraz of Spain in the last eight, the first time two teenagers have made that stage at a Grand Slam since 1994.
He also becomes the first Danish male player in a Grand Slam last eight in 55 years and next plays Norway's Carsten Ruud in an all-Scandinavian quarter-final.
Fourth seed Tsitsipas, hunting for his first Grand Slam title, started well and broke the Dane to go 3-1 up when Rune's drop shot was not short enough and the Greek whipped a cross-court winner past him.
Rune, a former junior champion in Paris at the age of 16, broke twice, clinching the set with a disputed line call that went in his favour.
