Jannik Sinner powered past Grigor Dimitrov in straight sets Tuesday to reach his first French Open semi-final, where he could face rival Carlos Alcaraz, on the day he secured the world number one ranking. The Australian Open champion, who will move top of the rankings next week after Novak Djokovic's withdrawal from the tournament, eased to a 6-2, 6-4, 7-6 (7/3) victory and will take on either Alcaraz or Stefanos Tsitsipas in the last four. Sinner's achievement of becoming Italy's first number one in the sport was confirmed during his match, as the injury-enforced withdrawal of Djokovic was announced.
