Tiafoe Rallies From 2 Sets Down to Reach US Open Semis

Frances Tiafoe was down two sets, a break, and staring at elimination when something clicked inside Arthur Ashe Stadium.

The 28-year-old American refused to quit. With Michelsen serving for the match at 5-4 in the third set, Tiafoe roared back to win 5-7, 3-6, 7-5, 6-3, 7-6 in four hours and 38 minutes, reaching his third US Open semifinal in five years.

But the victory was bittersweet. At the net, 22-year-old Michelsen broke down in tears as Tiafoe wrapped him in a long embrace, whispering encouragement to his friend who had just played the match of his life in his first Grand Slam quarterfinal.

"He's a great guy for consoling me in that moment," Michelsen said afterward. "I was trying to keep it together, and I didn't do a good job of that. He was saying a lot of nice personal things."

The unseeded Michelsen had dominated the first two hours, firing winners and outplaying the 11th seed. He hadn't dropped a set all tournament and seemed destined for his first major semifinal.

Then Tiafoe found another gear. The New York crowd, always his biggest cheerleader, erupted as he broke back and stole the third set. He raced through the fourth and survived a wild fifth set decided by a 10-point tiebreak.

Why This Inspires

This wasn't just about tennis. Tiafoe's transformation over the past year shows what's possible when someone commits to change at any age.

After a disappointing third-round loss last year, critics questioned his fitness and commitment. At 28, when many players are set in their ways, Tiafoe overhauled everything: new coach, new training routine, new mindset.

"I'm just a different person in general," Tiafoe said. "I'm not that person who I was when I made [the semifinals] in 2022 and when I made one in 2024."

Former doubles champion Ryan Harrison put it perfectly: "This time last year he was losing matches because of his fitness, now here we are four hours and 40 minutes into a match and he's raining down the fastest serve of the match."

The work nobody saw in the gym became the difference everyone watched on television. Tiafoe's willingness to hear hard truths, make difficult changes, and stay routine-oriented all year finally paid off on the sport's biggest stage.

For Michelsen, Tiafoe had only encouragement: "He's a hell of a player and he easily could have won today." The younger American promised through tears that he'd be back, and after this performance, nobody doubts him.

Tiafoe will face either defending champion Carlos Alcaraz or eighth seed Ben Shelton in the semifinals, still chasing his first US Open final.
