The first round of the 2025 Australian Open has wrapped up with a few major upsets on the men’s side.
Alex Michelsen def. (No. 11) Stefanos Tsitsipas 7-5, 6-3, 2-6, 6-4
Unseeded 20-year-old American Alex Michelsen gets the biggest win of his career with a four-set victory over 2023 runner-up Stefanos Tsitsipas in the first round of the Australian Open. The deciding fourth set was close, but Tsitsipas made a costly error, double-faulting on break point in the ninth game. This marked Michelsen’s first Top 20 win at a Grand Slam, and he has moved up to a career-high No. 41 in the live ATP Rankings.
