Croatia's Marin Cilic fired 33 aces past seventh-seeded Andrey Rublev to reach his first French Open semi-final on Wednesday with a 5-7, 6-3, 6-4, 3-6, 7-6 (10/2) win. Cilic, the 2014 US Open champion, also crashed 88 winners in the four-hour 10-minute tie and will play either eighth-seeded Casper Ruud of Norway or Danish teenager Holger Rune for a place in Sunday's final. The 33-year-old Cilic becomes only the fifth active men's player after Novak Djokovic, Rafael Nadal, Roger Federer and Andy Murray to make the semi-finals at all four Slams.
