Auger-Aliassime upends 3rd top-15 player to reach U.S. Open semifinals

Canada's Felix Auger-Aliassime is off to the U.S. Open semifinals for the second time after a wild fourth-set comeback on Wednesday in New York City.

The Montreal native rallied from 2-5 down in the fourth set to defeat Australian Alex de Minaur 4-6, 7-6 (7), 7-5, 7-6 (4). The run matches Auger-Aliassime's deepest Grand Slam result, equalling his 2021 semifinal at Flushing Meadows.

"Four years ago. It feels like more," said Auger-Aliassime, who advanced back then when Carlos Alcaraz stopped playing in the quarterfinals with an injured leg muscle. "It was a tough couple of years."

Auger-Aliassime, the 25th seed, will face the winner of Wednesday's other quarterfinal between top-ranked Jannik Sinner and 10th-seeded Lorenzo Musetti, both of Italy. No. 2 Alcaraz faces No. 7 Novak Djokovic in the other semifinal.

The 25-year-old Canadian won three straight games to knot the final set at 5-5. After de Minaur restored his lead at 6-5, Auger-Aliassime dropped just one point to send the set to a tiebreaker.

Up 6-4 and serving for match point, Auger-Aliassime ripped a forehand that de Minaur sent long, prompting the Canadian to raise his racket to an ovation at Arthur Ashe Stadium.

Auger-Aliassime was one point from trailing two sets to none when de Minaur led 6-5 in the second-set tiebreaker. But Auger-Aliassime erased that set point with a 120 mph ace. That began a run in which he grabbed four of five points to
