Croat Marin Cilic and Norwegian Casper Ruud reached the French Open semifinals for the first time in their careers Wednesday after two big-hitting displays overwhelmed their opponents.
Cilic fired 33 aces and 88 winners past seventh-seeded Andrey Rublev in a 5-7, 6-3, 6-4, 3-6, 7-6 (10/2) win.
Eighth seed Ruud booked a clash against the 33-year-old Croat when he became the first Norwegian man to reach a Grand Slam semifinal with a 6-1, 4-6, 7-6 (7/2), 6-3 victory over Danish teenager Holger Rune.
The 2014 U.S. Open champion, Cilic needed 4 hours and 10 minutes to defeat Rublev, who has now lost all of his five quarterfinal appearances at the Slams.
The 20th seeded Cilic becomes only the fifth active men's player after Novak Djokovic, Rafael Nadal, Roger Federer and Andy Murray to make the semifinals at all four majors.
"The fifth set was an incredible battle," said Cilic who is in his first Grand Slam semifinal in four years.
"Andrey played so well. Today was my day. He just didn't have the luck."
Rublev grabbed the first set but wilted under a Cilic barrage over the next two.
The Croat had stunned world No. 2, Daniil Medvedev, in the fourth round and he rediscovered that free-swinging assault to level the contest with a 17th ace on a fifth set point.
He pocketed the third with a lone break in the seventh game.
Rublev, who had lost to Cilic at the Australian Open in January, battled back with a crucial break in the eighth game of the fourth set.
Cilic, the 2017 Wimbledon and 2018 Australian Open runner-up to Federer, had a match point saved in the ninth game of the decider but swept through the super tiebreaker.
'Serving very well'
"He was serving very well," said Rublev.
"I relaxed after the first set but then I wasn't thinking.
"I could not manage the emotions in the previous quarter-finals. Today I was close to the semifinal."
Rune, ranked 40, had knocked out fourth seed and 2021 runner-up Stefanos Tsitsipas in the fourth round.
The 19-year-old was bidding to become the first Danish man to reach the last-four in Paris and first at any Slam since Jan Leschly at the 1967 U.S. Championships.
However, Ruud overpowered the youngster, firing 13 aces and 55 winners while Rune had to fight off 12 of 17 break points carved out by the Norwegian.
"I started the match well, but Holger raised his level of play, he came back and it was tough until the end," said Ruud after beating the Dane for the fourth time in four meetings.
"I had met him three times and he is improving. He has become unpredictable, he isn't afraid of anything and will be dangerous for the next few years," added Ruud who had never passed the round of 16 in a Grand Slam before this French Open.
Friday's other semifinal will see 13-time champion Rafael Nadal take on Alexander Zverev after his epic quarterfinal win over Novak Djokovic.
