Alex Michelsen Upsets Tsitsipas at Australian Open

American tennis player Alex Michelsen stunned 2023 Australian Open finalist Stefanos Tsitsipas in a first-round upset at the 2025 Australian Open with a score of 7-5, 6-3, 2-6, 6-4. Michelsen, at 20 years old, showcased bold and confident play, including 46 winners and pivotal break points aided by his powerful baseline game. Tsitsipas, the 11th seed, has now faced three consecutive Grand Slam losses, including first-round exits at both the US Open and the Australian Open, raising concerns about his performance on the tour. The Greek player had decided to conserve energy for singles by withdrawing from doubles with his brother, a decision he later regretted. Michelsen credited his mother for his early tennis development and maintained composure under pressure, earning a significant career milestone. This victory marks Michelsen's first win against a top-20 player in a Grand Slam, propelling him into the tournament's second round.
