Alexander Zverev advanced to the US Open semi-finals on Wednesday after securing a 6-2, 7-5, 6-1 victory over Botic van de Zandschulp on Arthur Ashe Stadium. The win marks the first time Zverev has reached the semi-finals of all four Grand Slam tournaments in a single season. The German player previously remained up until 3:30 a.m. to watch the conclusion of the quarter-final match between Ben Shelton and Carlos Alcaraz. On the other side of the bracket, Karen Khachanov moved into the semi-finals after Alexander Blockx retired from their match while trailing 6-2, 7-5, 3-2 due to back and rib injuries. Zverev and Khachanov will now face each other for a spot in the final. This tournament run brings Zverev’s season total to 23 major singles wins, establishing a record for a German man.
