Young American Sends Shockwaves With Win Over Tsitsipas
Not many expected the first big shock of the 2025 Australian Open to arrive so soon or in such dramatic style. Yet Alex Michelsen, a 20-year-old American with a fearless game and barely two years into his pro tennis career, just took out Stefanos Tsitsipas—an 11th seed and last year's finalist—right on Rod Laver Arena. The final score: 7-5, 6-3, 2-6, 6-4. If you blinked, you missed the start of what could be this tournament's breakout story.
People might not have had Michelsen on their radar, but that didn't faze him. Ranked 42nd in the world, he stepped on court with a game plan full of intent. From the first ball, he set the tone: bold serves, early ball striking, and a willingness to charge the net. Tsitsipas, known for his smooth groundstrokes and court coverage, simply couldn't settle into his rhythm. Michelsen kept finding ways to disrupt the Greek’s patterns, especially when pressure mounted late in the sets.

Bold Moves, Big Moments, and Unforced Errors
Michelsen’s win owed a lot to how he handled the match’s most intense moments. In the opening set, he converted a crucial break at 6-5, pouncing on loose points from Tsitsipas. The second was more of the same. Michelsen dug in on his return games, forcing errors from the usually reliable Tsitsipas backhand. Things briefly swung Tsitsipas’ way in the third set—he found that extra gear and took it 6-2. But instead of folding, Michelsen reset fast. He ramped up the aggression all over again in the fourth, making clear he was there to play his way, not react to expectations.
Throughout the match, Tsitsipas was clearly frustrated, and it showed in his count of unforced errors and double faults. The most telling came right at 5-all in the fourth set. After a tense rally, Tsitsipas handed Michelsen a break on a double fault—the crowd groaned, but the American didn’t flinch. He served out the match like he’d done it a hundred times before, looking anything but a newcomer to the grand slam stage.
The highlight reel moment? Michelsen engineering a hot shot that left Tsitsipas standing. Instead of going for the expected big power play, he used a soft, perfectly timed touch at the net for the point. It was the sort of move you see from players who know exactly who they are on court—smart, gutsy, and packed with personality.
After shaking hands at the net, Michelsen later told the press that his game plan was all about execution and mindset. He summed it up with, "I knew it would be a battle and stayed super composed." Hard to argue with that when you’ve just taken down one of the sport’s established stars.
This victory is more than just a first major upset—it's the biggest win of Michelsen’s career and a signal that the new wave of tennis talent is here, ready to rattle the old order. As he moves into the Australian Open’s second round, all eyes will be on what comes next for this brash, unflinching American who just changed the energy of the slam, one bold point at a time.
