NEW YORK, United States | September 9, 2026 —
US Open 2026 produced one of its most dramatic matches as Frances Tiafoe completed an extraordinary comeback from two sets down to defeat fellow American Alex Michelsen and reach the men’s singles semifinals at Flushing Meadows.
Tiafoe survived a match that lasted more than four and a half hours, eventually winning 5-7, 3-6, 7-5, 6-3, 7-6 (10-6) inside Arthur Ashe Stadium.
The American No. 11 seed appeared close to elimination after Michelsen controlled the opening two sets and moved within touching distance of the biggest Grand Slam victory of his career.
Instead, Tiafoe transformed the match.
He recovered his rhythm, increased his aggression and turned a seemingly lost quarterfinal into another memorable New York comeback.
Tiafoe Comes Back From Two Sets Down
Michelsen entered the quarterfinal having not dropped a set during the tournament.
That form continued early.
The 22-year-old repeatedly attacked Tiafoe’s serve and broke the more experienced American several times during the opening stages.
Michelsen took the first set 7-5 before strengthening his grip on the match by winning the second 6-3.
Tiafoe then fell behind again in the third set.
At that stage, Michelsen looked poised to reach his first Grand Slam semifinal.
But Tiafoe refused to concede.
Third Set Changes the Match
The third set became the turning point.
Tiafoe raised his intensity and began finding more depth and pace from the baseline.
Michelsen still remained close to victory, but crucial errors while trying to close out the contest gave Tiafoe an opportunity.
The 28-year-old took advantage.
He captured the third set 7-5 and suddenly brought the Arthur Ashe Stadium crowd fully back into the match.
That shift in momentum proved decisive.
Tiafoe Dominates Fourth Set
Once Tiafoe found his rhythm, the contest changed dramatically.
He played with greater confidence in the fourth set and began dictating more rallies.
His forehand became increasingly dangerous, while his improved serving allowed him to shorten points and reduce Michelsen’s opportunities to attack.
Tiafoe won the fourth set 6-3.
After nearly four hours of tennis, the all-American quarterfinal headed into a deciding fifth set.
Michelsen Leads Again in Fifth Set
Even then, Michelsen refused to disappear.
The young American moved ahead early in the final set and once again placed Tiafoe under enormous pressure.
However, Tiafoe responded with the same resilience that had brought him back into the match.
He recovered the break and forced the contest toward a deciding tiebreak.
Neither player could afford another major mistake.
Tiafoe Wins Deciding Tiebreak
The final-set tiebreak produced another tense battle.
Tiafoe ultimately showed greater composure in the decisive moments.
He won the tiebreak 10-6, sealing the match after approximately 4 hours and 38 minutes of play.
The victory sparked huge celebrations inside Arthur Ashe Stadium.
Tiafoe had completed one of the most difficult comebacks of the tournament.
Third US Open Semifinal for Tiafoe
The result sends Tiafoe into the US Open semifinals for the third time.
He previously reached the last four in 2022 and 2024.
All three of his career Grand Slam semifinal appearances have now come in New York.
That record highlights the unusual connection between Tiafoe and the US Open.
The American regularly produces some of his best tennis in front of the home crowd at Flushing Meadows.
Tiafoe Keeps American Men’s Title Hopes Alive
Tiafoe’s run also carries broader significance for American tennis.
No American man has won the US Open singles title since Andy Roddick captured the trophy in 2003.
That drought has continued despite several strong generations of U.S. players.
Tiafoe now has another opportunity to challenge it.
His deep run comes during a tournament in which American players have enjoyed particularly strong representation.
Six U.S. singles players reached the quarterfinal stage across the men’s and women’s draws, the most at the tournament since 2002.
Michelsen Leaves After Breakthrough Tournament
The defeat will be painful for Michelsen, but his 2026 US Open remains a major breakthrough.
He reached his first Grand Slam quarterfinal and entered the match against Tiafoe without dropping a set.
Michelsen also became one of the youngest American men in recent years to make such a deep run in New York.
His ability to push an experienced US Open semifinalist across five sets demonstrated how rapidly he has developed.
Tiafoe Shows Sportsmanship After Thriller
One of the most memorable scenes came after match point.
Tiafoe embraced an emotional Michelsen at the net and offered words of encouragement to his compatriot.
The gesture drew attention after an exhausting match in which both players had pushed themselves physically and mentally.
Tiafoe later praised Michelsen’s level and future potential.
The moment added another dimension to a match already defined by competitive intensity.
Tiafoe’s 2026 Season Continues to Improve
Tiafoe entered New York after a productive North American hard-court season.
He reached the Cincinnati final shortly before the US Open and arrived at Flushing Meadows with growing confidence.
Earlier in 2026, he also won the Halle title.
His US Open record now stands at five wins from five matches this year.
The challenge becomes significantly harder from here.
Who Will Tiafoe Play in the Semifinal?
Tiafoe’s semifinal opponent comes from the blockbuster quarterfinal between defending champion Carlos Alcaraz and Ben Shelton.
Both players present very different challenges.
Alcaraz brings Grand Slam experience, elite movement and exceptional shot-making.
Shelton brings explosive serving, power and the advantage of another strongly pro-American crowd.
For Tiafoe, however, the immediate focus will be physical recovery after spending almost five hours on court.
