Ethan Quinn upset pre-match favourite Hubert Hurkacz 6–4, 7–6, 6–1 in the first round of the Australian Open on hard court on 22 January 2026. Despite entering as a 3.9 outsider against Hurkacz's 1.24 odds, Quinn controlled proceedings throughout, breaking serve in the opening set before claiming a tight second-set tiebreak and dominating the third. The result marks a significant scalp for Quinn early in the Australian summer and raises questions about Hurkacz's form heading into the year's opening Grand Slam.
