American tennis player Alex Michelsen achieved his first Masters 1000 win on Saturday by defeating fellow American and close friend Learner Tien in the Round of 16 at the National Bank Open in Toronto. This victory marks a significant milestone as Michelsen advances to the quarterfinal stage of this prestigious tournament for the first time in his career.
Following a notable win against No. 3 seed Lorenzo Musetti in the Round of 32, Michelsen continued his strong performance by overcoming Tien in straight sets, securing 72% of his first-serve points throughout the match. Tien, meanwhile, struggled with consistency on serve, committing eight double faults and winning only five service games in the 6-3, 6-3 loss.
Michelsen Reflects on the Importance of the Win
After the match, Michelsen expressed his excitement during an on-court interview, emphasizing the significance of this career moment. He stated,
“Yeah it feels really good, like I said in the other interview, uncharted territory from this point on. Super happy being in the quarters for the first time.”

A Unique Battle Between Close Friends
Both Michelsen and Tien, who are American players close in age, have known each other since their early days of training and have developed a close friendship over the years. Despite competing against each other for a spot in the quarterfinals of a Masters 1000 event, their camaraderie remained intact as they exchanged memes leading up to their match.

In his interview, Michelsen shared,
“We’re very, very close friends, we’ve been talking, sending each other memes, just like normal, and I mean, we’ve grown a lot together, we came from when we were not very good, and now we’re playing Round of 16 at a 1000, it’s super special. I knew one of us was going to be in the quarter so I was happy stepping on the court today.”

With this win, Michelsen climbed to No. 33 in the ATP live rankings, while Tien’s run to the Round of 16 has elevated him to No. 55, placing him just behind Joao Fonseca, a fellow 2024 ATP Next-Gen finalist.
Potential Opponents Awaiting Michelsen in the Quarterfinals
Looking ahead, Michelsen will face the winner of the match between No. 8 seed Casper Ruud and No. 11 seed Karen Khachanov. This will be Michelsen’s first time competing against Ruud, while he holds a recent victory over Khachanov gained at this year’s Australian Open.
Earlier this season, Michelsen secured a surprising first-round victory over former top-ranked Stefanos Tsitsipas before beating Khachanov in straight sets to reach the fourth round, where he was ultimately defeated by Alex de Minaur.
Both Ruud and Khachanov are ranked higher than Michelsen heading into the National Bank Open, making a victory against either opponent critical in establishing Michelsen as a strong contender as the US Open approaches later this month.
Significance of Michelsen’s Breakthrough in the ATP Tour
Alex Michelsen’s breakthrough at the National Bank Open is a pivotal moment in his tennis career, demonstrating his ability to compete and win against higher-ranked, experienced players at the Masters 1000 level. As he advances further in the tournament, this success could boost his confidence and ranking, enhancing his presence in upcoming major tournaments like the US Open.
His progression also highlights the emergence of young American talent in the global tennis scene, with both Michelsen and Tien making significant strides in important ATP events. The upcoming quarterfinal match will serve as a crucial test for Michelsen’s continued development against top-tier competition.
