Jannik Sinner advanced to the semi-finals in Rotterdam on Friday after Milos Raonic, plagued by injury, retired at 1-1 in the second set of their quarter-final match.
Australian Open champion Sinner, seeded first, claimed the opening set 7-6 (7/4) before the 33-year-old Canadian, known for his powerful shots, conceded the match after just two more games. Sinner will now face Dutch player Tallon Griekspoor, who defeated Emil Ruusuvuori of Finland 7-5, 7-6 (7/4) to secure a spot in Sunday's final.
