Frances Tiafoe staged a dramatic comeback from two sets down to defeat Alex Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 (10-6) in the US Open quarterfinals. The victory, which took 4 hours and 38 minutes, marked the first time since Roger Federer in 2014 that a player recovered from a two-set deficit in a US Open men's quarterfinal. Tiafoe, visibly emotional, comforted a tearful Michelsen at the net after the match.

The No. 11-seeded American reached his third US Open semifinal, joining Andre Agassi as the only American men to achieve this feat in the century. Tiafoe will face the winner of the Carlos Alcaraz vs. Ben Shelton match. Michelsen, ranked No. 46, fell to 0-6 in fifth-set matches.
