MELBOURNE, Australia (AP) 鈥� Alex Michelsen produced the biggest win so far of his fledgling career to upset 2023 runner-up Stefanos Tsitsipas in the first round of the , and he knew instinctively where credit was due.
The 20-year-old American overcame nerves on his serve in the fourth set before clinching a 7-5, 6-3, 2-6, 6-4 win Monday over Tsitsipas, a 26-year-old from Greece who has a career-high No. 3 ranking and has contested two Grand Slam finals.
Michelsen started playing tennis around age 3 and hit most days as a kid with his mother, Sondra, a school teacher who played college tennis.
鈥淵eah, I鈥檓 sure she鈥檚 watching right now,鈥� Michelsen told the crowd on John Cain Arena, one of the three main show courts at Melbourne Park. "Yeah, we hit a million balls from the baseline every day. We鈥檇 go like 30 minutes up the middle, then we go across each way for like an hour and a half.
鈥淚 mean we would just go out there and she would never miss a ball 鈥� she鈥檚 incredible. But no chance I鈥檇 be here without without her, so thanks Mom. Love you."
The No. 42-ranked Michelsen reached the third round last year on his Australia debut before losing in the first rounds at Roland Garros and Wimbledon and in the second round at the U.S. Open.
His win over Tsitsipas was Michelsen's first against a player ranked in the top 20 at a Grand Slam.
He played with freedom against Tsitsipas, taking big swipes with his service returns 鈥� including three in the ninth game of the fourth set that helped earn him a vital break.
He got a bit tense on serve, surrendering two hard-earned breaks in the fourth set, but stayed composed in the last game.
鈥淵eah, I didn鈥檛 take the most direct path, that鈥檚 for sure. Shouldn鈥檛 have got broken twice in the fourth. My serve let me down. Served double faulting way too much,鈥� he said. "But I was also returning really, really well. I felt like I was winning most of the baseline rallies when I was inside the baseline and controlling the point.
鈥淪o I was thinking at 4-all, after I got broken twice, saying, 鈥榊ou鈥檙e still in this, just play every point for what it is.鈥� I played a great 4-all game and got it done at 5-4.鈥�
He finished the match with eight aces and eight double-faults, but hit 46 winners to only 40 unforced errors.
鈥淔irst of all, I was just trying to stay super composed out there. I knew it was going to be a battle in the end,鈥� he said. "It鈥檚 all about the mindset.鈥�
