Alex Michelsen stuns Tsitsipas in Australian Open

American Alex Michelsen shocks Stefanos Tsitsipas in first round of Australian Open, claiming biggest career win.

American Alex Michelsen claimed the biggest win of his career when he stunned Stefanos Tsitsipas 7-5, 6-3, 2-6, 6-4, in the first round of the Australian Open on Monday (January 13, 2025) as the Greek 11th seed became the first major casualty at Melbourne Park.

Michelsen had beaten Tsitsipas at the Japan Open last year and the 20-year-old American kept his unbeaten record against Tsitsipas, a 2023 finalist at the Melbourne Grand Slam.

Michelsen kept his cool under pressure on rallies and found success at the net while his baseline game looked effortless as he fired 46 winners past Tsitsipas, who had pulled out of the doubles draw at Melbourne Park to focus on his singles campaign.

"My whole role was to try to go deep into the Australian Open. I knew the first thing I had to consider was not play doubles," said Tsitsipas, who also exited last year's U.S. Open in the first round.

"I guess karma hit me, I was not able to deliver or play the way I was hoping to... The whole purpose was just to save up on some energy and be fresher hopefully in the deeper draw of the tournament."

Tsitsipas looked well in control in the first set but midway through he began making several errors off Michelsen's serve before the American pounced in the 12th game, taking the set with a backhand winner down the line.

The turning point in the second set came when Michelsen was 4-3 up and he produced a disguised forehand drop shot that left Tsitsipas well short as the crowd roared its approval.
