The Aporia
Carlos Alcaraz advanced to the Japan Open semifinals on Sunday after Denis Shapovalov retired due to a hip injury during their quarterfinal match in Tokyo. Alcaraz led 7-6 (4), 2-1 after 82 minutes when Shapovalov, visibly restricted by his injury despite an off-court medical timeout, was unable to continue playing. The Canadian had pushed the Spaniard hard in the opening set, earning a set point at 5-4 before Alcaraz prevailed with a tiebreak. Earlier Sunday, Jaume Munar secured a spot in the semifinals by defeating Kyrian Jacquet of France 6-4, 6-2. Alcaraz will face his compatriot Munar next.
