Tiafoe's Epic Comeback Sends Him To US Open Semifinal
Tiafoe conquers Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 to reach US Open semifinal
Tiafoe roars back from a two-set deficit to eliminate Michelsen in 4 ½ hours
For one, it was elation and relief; for the other, anguish and disbelief. Alex Michelsen, just twenty-two, had achieved a career-high rank of 30 but was not seeded due to his current rank of 46. Although he had made three tour-level finals, he was still in search of his first title.
In three previous outings in New York, he had not progressed past the second round. During this fortnight, he had not dropped a set through four rounds, including wins over two seeded players: Brandon Nakashima #16 and Tomas Etcheverry #27.
Frances Tiafoe, the world #12 and 11th seed, is familiar with the later stages of the US Open. In 2023, he made the quarters, while in 2022 and 2024 he reached the semis. His loss last year in the third round compelled him to retool his fitness and mindset, and it has clearly paid dividends.
In the first round on Armstrong Stadium, he required five sets to subdue countryman Martin Damm Jr. That victory was a microcosm of the past twelve months and the commitment he made to himself and his team. In the following three rounds, he did not drop a set.
Today on Arthur Ashe Stadium, it was a different story. After trading breaks in the first two games, Michelsen held to 15 with two winners, including a 133mph ace up the tee, while Tiafoe faced double break point and dumped serve. Michelsen opened the fifth with an ace up the tee but gave back the break when Tiafoe struck two consecutive backhand volley winners.
In the following game, the 11th seed faced break point and deuce but held to level at three with his first ace. Michelsen remained composed while exuding confidence. He made 5/5 first serves,including an ace up the tee on game point to lead 4-3. Tiafoe, serving with new balls, held to 15 to level.
