Aussie, Aussie, Aussie! Alex de Minaur’s US Open 2025 Run Ignites Fans After Interviewer’s Swoon and Altmaier’s Retirement
Alex de Minaur, Australia’s No. 1 tennis star and world No. 8, electrified the US Open 2025 crowd on August 30, 2025, advancing to the fourth round after Germany’s Daniel Altmaier retired due to a thigh injury during their third-round clash on Louis Armstrong Stadium, with de Minaur leading 6-7(4), 6-3, 6-4, 2-0. The nearly three-hour battle showcased de Minaur’s trademark speed and tenacity, but it was the post-match interview that stole headlines, as a US interviewer gushed over his recent Washington ATP title and engagement to Katie Boulter, sparking a rousing “Aussie, Aussie, Aussie!” chant from the New York crowd (nine.com.au, August 31, 2025). As de Minaur prepares to face Leandro Riedi for a quarterfinal spot, his performance and charm have fans buzzing. This article dives into the match, the interviewer’s viral moment, de Minaur’s campaign, and how fans in the UK, USA, Australia, and Nigeria can follow his journey, as of 12:38 AM WAT, Monday, September 1, 2025.
De Minaur’s Gritty Win Over Altmaier
The third-round match pitted de Minaur against an exhausted Altmaier, who had endured nearly 10 hours on court in his first two rounds, including grueling five-set victories over Hamad Medjedovic and Stefanos Tsitsipas (nine.com.au, August 31, 2025). Altmaier took the first set in a 7-6(4) tiebreak, capitalizing on de Minaur’s early unforced errors. However, the Australian’s relentless defense and court coverage turned the tide, as he claimed the second set 6-3 and the third 6-4. Altmaier, visibly hampered by a thigh injury requiring a medical timeout in the third set, retired early in the fourth, handing de Minaur the win (usopen.org, August 30, 2025).
De Minaur showed class in victory, praising his opponent: “I’ve got nothing but the most respect for Daniel. He’s a hell of a warrior, hell of a competitor… I wish him a very quick recovery” (nine.com.au, August 31, 2025). His performance included 28 winners and a 78% first-serve point win rate, underscoring his hard-court prowess (usopen.org, August 30, 2025). Fans on X lauded his heart, with @TheTennisLetter tweeting, “Demon’s speed and sportsmanship are unreal. Class act wishing Altmaier well! #USOpen” (August 30, 2025).
Interviewer’s Swoon and “Aussie, Aussie, Aussie!” Chant
The post-match interview with Stan Sport’s Duncan McKenzie-McHarg became a viral sensation. The US interviewer celebrated de Minaur’s 10th ATP singles title in Washington, D.C., in July 2025, then turned personal, saying, “Speaking of titles, Washington was pretty big, but none bigger than the title of Katie Boulter’s fiancée. Congratulations on that. Honestly, it’s one of the funnest things to see” (wwos.nine.com.au, August 30, 2025). The crowd erupted into a spirited “Aussie, Aussie, Aussie!” chant, leaving de Minaur beaming as he soaked in the support (brisbanetimes.com.au, August 31, 2025).
The interviewer’s enthusiasm, described as “swooning” by outlets like Nine, highlighted de Minaur’s likability and his high-profile engagement to British star Katie Boulter, announced earlier in 2025 (nine.com.au, August 31, 2025). The moment resonated on X, with @TennisFanatic tweeting, “US interviewer fanboying over Demon and Katie is everything! That chant was epic! 🇦🇺 #USOpen” (August 30, 2025). Videos shared by @usopen captured the crowd’s energy, amplifying de Minaur’s growing fanbase (August 30, 2025).
De Minaur’s US Open Campaign
De Minaur’s path to the fourth round included straight-set wins over Christopher O’Connell (6-3, 6-4, 6-4) and Shintaro Mochizuki (6-2, 6-4, 6-2) in the first and second rounds (usopen.org, August 29, 2025). His next opponent, Swiss qualifier Leandro Riedi (world No. 435), upset Francisco Cerundolo but faces a tough challenge against de Minaur, who called him “very dangerous” with “a lot of firepower” (nine.com.au, August 31, 2025). The Australian’s 26-8 hard-court record in 2025, including his Washington title, makes him a favorite (tennis.com.au, August 22, 2025).
The withdrawal of Ben Shelton due to a shoulder injury has opened de Minaur’s draw, with a potential quarterfinal against Taylor Fritz or Casper Ruud (nine.com.au, August 30, 2025). A semi-final clash with Novak Djokovic or Jannik Sinner looms, testing de Minaur’s bold prediction that neither Sinner nor Carlos Alcaraz will win the title (EssentiallySports, August 30, 2025). His 2024 US Open quarterfinal run remains his career-best at a Grand Slam, and he’s poised to match or surpass it (abc.net.au, August 22, 2025).
