Frances Tiafoe and Taylor Fritz have secured an all-American semifinal at the U.S. Open, marking the first time in 18 years that the United States is guaranteed a man in the title match at the country's Grand Slam tournament.
Tiafoe, seeded 20th, advanced to the semifinals for the second time in three years after his quarterfinal opponent, Grigor Dimitrov, retired from the match due to injury in the fourth set. Tiafoe was leading 6-3, 7-6 (5), 6-3, 4-1 when Dimitrov stopped playing, leading to an anticlimactic end to the match.
