Ben Shelton defeated Carlos Alcaraz 6-7 (5), 6-1, 6-3, 1-6, 7-6 (7) in a historic US Open quarterfinal that ended at 3:33 a.m., the latest finish in tournament history. The 23-year-old American secured his first win over a top-three player and reached his third major semifinal, second in New York. After dropping the first set in a tiebreak, Shelton surged with nine straight games to lead two sets to one.

Alcaraz fought back in the fourth, winning 6-1 after Shelton struggled with unforced errors. The deciding set went to a tiebreak, where Shelton clinched victory with a 146 mph ace. Alcaraz, who had never lost to an American at a Slam before, congratulated Shelton and praised his resilience.

Shelton said it was the most enjoyable match of his career, calling it a "war" against one of the sport's greatest champions. The win ended Alcaraz's 18-match Slam winning streak and marked his first major loss to a left-handed player. Shelton is now one victory from his first major final.
