Alex Michelsen defeated Karen Khachanov at the Australian Open in the second round on hard court, securing a 6–3, 7–6, 6–2 victory. The result constituted a significant upset, as Khachanov entered as the pre-match favourite at odds of 1.6 to Michelsen's 2.5. Michelsen's composed performance across all three sets demonstrated control and consistency, particularly evident in the second-set tiebreak and the decisive third set. The American's straightforward progression suggests improved form heading deeper into the tournament, while Khachanov's early exit raises questions about his readiness at the year's opening Grand Slam.
