Frances Tiafoe and Taylor Fritz set up an all-American U.S. Open semifinal on Tuesday as compatriot Emma Navarro reached the women's last four to boost home hopes of a title sweep.
The 20th seed Tiafoe progressed when ninth-ranked Grigor Dimitrov suffered an injury in the third set of their quarterfinal and quit in the fourth with the score at 6-3, 6-7 (5), 6-3, 4-1.
Tiafoe also made the last four in 2022 while Fritz reached his first Grand Slam semifinal by defeating fourth-seeded Alexander Zverev 7-6 (7/2), 3-6, 6-4, 7-6 (7/3).
