Daniil Medvedev defeated John Millman 7–5, 6–2, 6–2 in the first round of the Australian Open on hard court on 18 January 2023, as expected given the Russian's commanding odds of 1.02 to Millman's 27.6. Medvedev controlled the match throughout, breaking serve multiple times to secure the opening set before dominating the final two frames with increasingly efficient tennis. The scoreline reflects the gulf in class between the world's elite and a lower-ranked challenger, with Medvedev advancing without significant resistance. The result maintains Medvedev's momentum at the year's first Grand Slam.
