Frances Tiafoe believes he is a different player and, more importantly, a different person from the man who captivated New York during his previous US Open runs.
The American star has another opportunity to turn that growth into Grand Slam glory after producing a remarkable comeback against fellow countryman Alex Michelsen to reach the US Open semifinals for the third time in his career.
Tiafoe, the 11th seed, survived an extraordinary quarterfinal battle, defeating the 22-year-old Michelsen 5-7, 3-6, 7-5, 6-3, 7-6(10/6) after four hours and 38 minutes of absorbing tennis.
It was the kind of victory that tested virtually every aspect of Tiafoe's game and character.
Yet, despite having already experienced the intensity of a New York semifinal twice before, the 28-year-old insists he is approaching this latest opportunity with an entirely different mindset.
“I'm just a different person in general. Those two runs were great, something I will cherish forever, but I'm not that person who I was when I made one in 2022 and when I made one in '24,” the 11th seed said in his post-match press conference Tuesday. “I'm not that person. I'm excited to see what this me does come Friday.”
Tiafoe's achievement places him in select company. By reaching the last four at Flushing Meadows for the third time, he became the first American man since Andre Agassi to accomplish the feat this century. Agassi reached the US Open semifinals in 2002, 2003 and 2005.
But while the occasion is familiar, Tiafoe's perspective has changed.
Rather than becoming overwhelmed by the significance of another deep run, the American says he is focused on remaining present and taking the tournament one match at a time.
“I just feel where my feet are. I'm pumped about it. I'm super excited about it, but I don't feel like it's — of course, I mean, this is a crazy match, so of course I'm extremely pumped up, but I don't feel like it's, ‘Oh, my God!’” I just want to continue,” explained the No. 8 player in the PIF ATP Live Rankings. “I just want to keep going. I have higher hopes for myself.”
Those higher hopes appeared to be in serious danger against Michelsen.
Tiafoe found himself two sets down and on the brink of elimination. Michelsen, who was making his own push for a breakthrough on the Grand Slam stage, served for the match at 5-4 in the third set.
But instead of folding under the pressure, Tiafoe produced another remarkable turnaround.
He clawed his way back into the contest, seized the momentum and eventually forced a deciding-set tiebreak. With the match balanced on a knife-edge, Tiafoe held his nerve to win the match tiebreak 10-6.
The victory marked his third career comeback from two sets to love down at a Grand Slam, following previous recoveries against Matteo Arnaldi in the opening round at Wimbledon in 2024 and against Jaime Faria in the third round of the French Open earlier this year.
“It was definitely a Braveheart-type win,” said Tiafoe, who completed his third comeback win from two sets to love down at a major (2024 Wimbledon R1 v. Arnaldi, 2026 Roland Garros R3 v. Faria). “It ranks pretty high in probably all-time wins in a slam. I don't know where, but it ranks pretty high.”
The dramatic nature of the contest was followed by an equally emotional moment at the net.
After the final point, Tiafoe and Michelsen shared a warm embrace. Michelsen, visibly overcome with emotion, cried on Tiafoe's shoulder as the magnitude of the battle and the disappointment of defeat appeared to sink in.
For Tiafoe, the match was another demonstration of the unique demands of tennis — a sport in which momentum can change in an instant and there is no clock to provide an escape.
“Three out of five is a blessing, because you have time to get it together. I definitely waited for the last minute,” said Tiafoe with a smile. “You see a little opening window, you see turning points. One point and all of a sudden you're, four hours later, in a battle just because of one point. Tennis is a unique sport like that.”
That resilience could prove crucial as Tiafoe prepares for another major semifinal.
He carries a 42-16 record this season, according to the Infosys ATP Win/Loss Index, and will next face either two-time US Open champion Carlos Alcaraz or fellow American Ben Shelton.
Whoever emerges from that quarterfinal will face an opponent who has already demonstrated that counting him out is a dangerous proposition.
For Tiafoe, however, this run is about more than simply repeating the success of 2022 and 2024.
He has returned to the stage he knows so well, but he believes the man standing under the New York lights this time is not the same one who stood there before.
Now he has the chance to show exactly what this new version of Frances Tiafoe can do.
