Casper Ruud moved into the French Open semi-finals for the first time on Wednesday courtesy of two big-hitting displays which 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 semi-final with a 6-1, 4-6, 7-6 (7/2), 6-3 victory over Danish teenager Holger Rune. Cilic, the 2014 US Open champion, needed four hours and 10 minutes to defeat Rublev who has now lost all of his five quarter-final 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 semi-finals at all four majors.
