Carlos Alcaraz sealed a spot in the men's semi-finals of the China Open with a straight-sets victory over Norway's Casper Ruud in Beijing on Monday. The world number two triumphed 6-4, 6-2 to set up a semi-final clash with either Jannik Sinner or Grigor Dimitrov. Alcaraz shook off an early break of serve to overpower the world number nine, eventually seizing an attritional first set with a 40-0 service game. He then took control, breaking twice without reply in set two before finally forcing Ruud to slice a backhand into the net. "To be able to win these kinds of matches the way I did gives you extra confidence in your game," Alcaraz said at a post-match news conference.
