Frances Tiafoe set up an all-American US Open semi-final against Taylor Fritz on Tuesday, guaranteeing a home player in the men's final for the first time in 18 years. Tiafoe, the 20th seed, progressed after ninth-ranked Grigor Dimitrov suffered an injury in the third set of their quarter-final and quit in the fourth with the score at 6-3, 6-7 (5/7), 6-3, 4-1. Tiafoe also made the semi-finals in 2022 while Fritz reached his first Grand Slam last-four by earlier defeating 2020 runner-up and fourth-ranked Alexander Zverev 7-6 (7/2), 3-6, 6-4, 7-6 (7/3).
