Ben Shelton defeats Carlos Alcaraz in record-late U.S. Open quarterfinal

American Ben Shelton defeated seven-time major champion Carlos Alcaraz in a five-set quarterfinal at the U.S. Open that concluded shortly after 3:30 a.m., setting a new record for the latest finish in the tournament's history. Shelton won 6–7(5), 6–1, 6–3, 1–6, 7–6(10–7) after a marathon match that lasted more than four hours.

The match, which began in the early hours of Wednesday, featured several high-velocity serves, including multiple first serves recorded at 140–146 miles per hour. Both players displayed aggressive play, with Alcaraz securing a break point early in the fifth set before Shelton saved it and later held serve to force a tiebreak.

Shelton's victory advances him to an all-American semifinal against Frances Tiafoe on Friday. The winner of that match will compete in the Sunday final, offering a chance to become the first American man to win a major since 2003.

"One of the most important, best passing shots he's hit ever," ESPN commentator John McEnroe said of Shelton's backhand pass in the fifth set.

The match took place amid routine stadium operations, including cleaning staff working in the suites and a DJ providing music for the late-night crowd. The extended duration highlighted the physical demands of Grand Slam competition and the endurance of both athletes.
