The Croatian is the fifth active man to complete a full set of at least one semifinal run at all four Slam events, joining Rafael Nadal, Novak Djokovic, Roger Federer and Andy Murray, each of whom has been ranked No. 1 and won multiple majors PARIS: Marin Cilic is 33, nearly eight seasons past his one Grand Slam title at the 2014 US Open — and, until Wednesday, more than four full years removed from his most recent trip to the semifinals of a major tournament. If he keeps serving like this, there’s no reason to think about quitting tennis anytime soon. Cilic delivered 33 aces to get to the final four at the French Open for the first time, edging No. 7 seed Andrey Rublev 5-7, 6-3, 6-4, 3-6, 7-6 (10-2) on Wednesday in a 4-hour, 10-minute test of strength and will. “Andrey played incredibly well. One had to go down,” the 20th-seeded Cilic said, “and today was my day.” The Croatian is the fifth active man to complete a full set of at least one semifinal run at all four Slam events, joining Rafael Nadal, Novak Djokovic, Roger Federer and Andy Murray, each of whom has been ranked No. 1 and won multiple majors. Cilic was the runner-up to Federer at Wimbledon in 2017 and the Australian Open in 2018; the latter had been Cilic’s most recent trip to a Slam semifinal. On Friday, Cilic will take on No. 8 Casper Ruud for a spot in the final. The other men’s semifinal is 13-time French Open champion Rafael Nadal, who eliminated Novak Djokovic in the quarterfinals, against No. 3 Alexander Zverev. Ruud, a 23-year-old from Norway, beat Rune, a 19-year-old from Denmark, 6-1, 4-6, 7-6 (2), 6-3 to get to his first Grand Slam semifinal. He might be a decade older than his next opponent, but Cilic feels good these days. When he had a physical exam at the end of 2021, he said, his doctor told him: “Your body’s like 25.” Continued Cilic: “Don’t tell my wife I’m saying this, (but) I might be playing another 10 years.” All kidding aside, he said: “How long? We’ll see. But definitely three, four years, if I can be competitive like this.” He dropped Rublev’s career mark in major quarterfinals to 0-5. That was thanks in part to Cilic’s overwhelming ability to strike serves and groundstrokes for winners — 88 in all, more than twice as many as Rublev’s total of 35. “It was hard emotionally, because he played some games very well,” Cilic said. “When you play this long, there’s always be some ups and down, so I had to keep my focus.” Rublev twice displayed good sportsmanship, indicating early in the tiebreaker that one of Cilic’s strokes was indeed in and, earlier at 1-all in the fifth set, volunteering to replay a point after Cilic complained that a shot that was called out had touched a line. As part of an agreement among the four Grand Slam hosts to standardize one element of the sport, this is the first time the French Open has used a tiebreaker in fifth sets of men’s matches — and third sets of women’s matches. Cilic ran away with the first-to-10 format against Rublev, collecting the match’s last nine points after trailing 2-1 in the tiebreaker. The 6-foot-6 (1.98 meter) Cilic has one of the biggest serves on tour, and he delivered them at up to 133 mph (214 kph) on Wednesday, with an average speed of 123 mph (199 kph). He came up with three aces in the tiebreaker. “Almost all the important points he was winning with his serve,” Rublev said, “and was really, really tough to read or to return.”
