Alex de Minaur’s US Open Quarterfinal Against Felix Auger-Aliassime: His Best Shot at Grand Slam Glory
Alex de Minaur faces a career-defining moment in the US Open quarterfinals against Felix Auger-Aliassime, where victory could propel the Australian star to his first Grand Slam semifinal. As the No. 8 seed rides a wave of momentum, many experts view this matchup on Arthur Ashe Stadium as de Minaur’s prime opportunity to break through in majors, given his hard-court prowess and the Canadian’s vulnerabilities.
The Matchup: De Minaur vs. Auger-Aliassime Breakdown
Alex de Minaur, the 26-year-old Australian, takes on Felix Auger-Aliassime, the 25-year-old Canadian, in a high-stakes US Open quarterfinal on September 4, 2025. De Minaur, seeded eighth, has dominated the tournament so far, dropping just one set en route to this stage, showcasing his baseline consistency and speed. Auger-Aliassime, seeded 12th, advanced with a gritty five-set win over Andrey Rublev, highlighting his powerful serve but exposing serving inconsistencies.
Their head-to-head stands at 8-3 in de Minaur’s favor, with the Australian winning the last five encounters, including a straight-sets victory at the 2024 Canadian Open. De Minaur’s defensive game and counterpunching style should neutralize Auger-Aliassime’s big first serve, especially on the faster New York hard courts. Analysts predict a four-set win for de Minaur, with his 85% first-serve points won rate giving him the edge.
The match, scheduled for prime time under the lights, promises drama as both players seek their first major semifinal. De Minaur’s recent form—reaching the Wimbledon quarters in July 2025—positions him as the favorite, but Auger-Aliassime’s upset potential keeps it competitive.
De Minaur’s Grand Slam Journey: Why This Is His Best Chance
De Minaur has long been Australia’s top male player, but Grand Slam success has eluded him despite consistent deep runs. His best results include quarterfinals at the 2020 US Open and 2024 Australian Open, but injuries and tough draws have blocked further progress. In 2025, he’s reached the fourth round at Roland Garros and Wimbledon, showing maturity at 26.
The US Open suits de Minaur’s aggressive baseline play and endurance on hard courts, where he’s won 70% of his matches this year. Unlike clay at Roland Garros or grass at Wimbledon, New York’s surface favors his speed and return game. With top seeds like Jannik Sinner and Carlos Alcaraz on the other side of the draw, a semifinal path looks clearer. Experts call this his “most winnable” major moment, given his peak fitness and Auger-Aliassime’s 0-4 semifinal record in Slams.

Background: De Minaur’s Rise and Grand Slam Struggles
Born in Sydney to a Uruguayan mother and Spanish father, de Minaur turned pro in 2015 and broke into the top 20 by 2019. He’s won 10 ATP titles, including the 2024 Acapulco 500, but majors remain elusive. A 2023 hip injury sidelined him for months, but 2025 has seen a resurgence, with a career-high ranking of No. 6 in June.
Auger-Aliassime, a former junior No. 2, reached the 2021 US Open semifinals but has struggled with consistency, winning just one title since. Their rivalry dates to 2016, with de Minaur’s tactical edge shining in recent meetings. The US Open’s $3.6 million winner’s check adds incentive, but for de Minaur, a deep run cements his status as Australia’s next Slam contender post-Nick Kyrgios’s injuries.
