US Open 2026 Day 13 Men’s Semifinal Preview: Ben Shelton and Frances Tiafoe Battle for History
The United States is guaranteed to have a representative in the US Open men’s final. The only question is whether Ben Shelton or Frances Tiafoe will seize the opportunity.
Shelton and Tiafoe will meet in an all-American semifinal on Friday, September 11, headlining the Day 13 schedule at the USTA Billie Jean King National Tennis Center. The winner will become the first American man to reach the US Open singles final since Andy Roddick in 2006.
It is a breakthrough moment for American men’s tennis, but neither player will be satisfied simply with getting this far. Both survived extraordinary five-set quarterfinals, both thrive in front of the New York crowd and both believe this could be the tournament that changes the course of their careers.
With two explosive athletes, enormous serves and an Arthur Ashe Stadium crowd searching for a home champion, the semifinal has all the ingredients for another US Open classic.
Shelton Stuns Defending Champion Alcaraz
Shelton produced the biggest victory of his career in the quarterfinals, eliminating defending champion Carlos Alcaraz 6-7(5), 6-1, 6-3, 1-6, 7-6 after four hours and 28 minutes.
The match finished at approximately 3:33 a.m., making it the latest finish in US Open history.
Shelton lost the opening set in a tiebreak but responded with some of the best tennis of his career. He overwhelmed Alcaraz during the second and third sets, weathered the Spaniard’s fourth-set response and then held his nerve in a deciding match tiebreak.
The eighth seed struck his serve at speeds approaching 150 mph and generated 54 unreturned serves. More importantly, he remained composed when the match became physical and unpredictable.
Shelton had entered the contest without a victory in 17 previous matches against top-three opponents. He did not merely end that run—he did it against the defending champion on the biggest tennis court in the world.
The result sends Shelton into his second US Open semifinal, three years after making his initial breakthrough in New York.
Tiafoe Completes an Unforgettable Comeback
If Shelton’s quarterfinal was improbable, Tiafoe’s escape against Alex Michelsen was every bit as dramatic.
Tiafoe trailed by two sets and a break before completing a remarkable 5-7, 3-6, 7-5, 6-3, 7-6 victory. Michelsen served for the match in the third set, but Tiafoe refused to surrender and gradually pulled the contest back in his direction.
After four hours and 38 minutes, Tiafoe secured his place in the US Open semifinals for the third time in five years.
The comeback captured everything that makes Tiafoe so dangerous in New York. He feeds off the crowd, embraces the theatre of a night session and often produces his most inspired tennis when a match appears to be slipping away.
Tiafoe will now try to take the final step that has eluded him in his previous semifinal appearances.
There will be pressure attached to that opportunity, but Tiafoe has repeatedly shown that Arthur Ashe Stadium brings out his personality rather than restricting it.
Shelton vs. Tiafoe Head-to-Head
Shelton leads the rivalry 3-1, but their two previous US Open matches were divided.
Shelton defeated Tiafoe in four sets in the 2023 quarterfinals, using his left-handed serve and fearless shot-making to announce himself as one of the most exciting young players in American tennis.
Tiafoe responded in the third round of the 2024 US Open, recovering from two sets to one down to win 4-6, 7-5, 6-7(5), 6-4, 6-3.
Those matches revealed how little separates them in New York. Shelton owns the larger serve and heavier forehand, while Tiafoe brings greater variety, improvisation and experience managing momentum over five sets.
The previous meetings also suggest that Friday’s semifinal could become a long, physical contest. Neither player is likely to panic if he falls behind, especially after what both accomplished in the quarterfinals.
The Battle for First-Strike Control
Shelton’s serve is the most imposing weapon in the matchup.
The left-hander can produce extreme pace down the middle and create sharp angles from the ad court. When his first serve lands, opponents often have little opportunity to establish a neutral rally.
Tiafoe will need to avoid becoming frustrated by stretches in which Shelton appears almost impossible to break. His objective should be to block returns deep, keep Shelton from immediately attacking with his forehand and apply pressure whenever a second serve appears.
Shelton will try to create the opposite dynamic when Tiafoe serves.
Tiafoe’s first delivery can be highly effective, but his second serve may come under pressure. Shelton will look to move forward, attack with his forehand and keep rallies short enough to protect his energy after the Alcaraz marathon.
The player who wins more of the exchanges immediately following the return will likely control the match.
Can Tiafoe Disrupt Shelton’s Rhythm?
Tiafoe should not attempt to trade uncomplicated power with Shelton for five sets.
His advantage lies in his ability to change the look of a rally. Tiafoe can use his backhand slice, vary his return position, move forward unexpectedly and create sharp angles from inside the baseline.
That variety can be particularly effective against Shelton, whose tennis is at its most dangerous when he has time to set his feet and unload.
Tiafoe should test Shelton’s movement with low balls and changes of direction. He can also use the occasional short return to force the younger American forward, where Shelton may not always be able to generate the same immediate power.
The danger is becoming too creative. Tiafoe has to use variety with a clear purpose rather than allowing the match to become a collection of low-percentage improvisations.
Shelton Must Control His Aggression
Shelton’s performance against Alcaraz demonstrated how much his game has matured.
The 23-year-old has always possessed spectacular weapons, but his decision-making and rally tolerance have improved. He committed fewer unforced errors than Alcaraz in the quarterfinal and showed that he can remain disciplined without losing his attacking identity.
He will need that same balance against Tiafoe.
Tiafoe is comfortable defending, changing direction and using an opponent’s pace. If Shelton attempts to finish every rally with one swing, he could give away the type of errors that allow Tiafoe to build confidence.
Shelton should use his serve to establish favourable court position, attack the Tiafoe backhand and move forward behind well-constructed approaches. The goal is not simply to hit harder. It is to prevent Tiafoe from controlling the geometry of the court.
Recovery Could Decide the Semifinal
Both Americans enter Day 13 following exhausting quarterfinals, making physical recovery an unavoidable part of the story.
Tiafoe spent four hours and 38 minutes on court against Michelsen. Shelton played for four hours and 28 minutes against Alcaraz, with the added challenge of finishing after 3:30 a.m.
Shelton has a full day away from competition before the semifinal, but recovering from such a late finish involves more than resting tired legs. His sleeping schedule, hydration and ability to restore his energy will all be tested.
Friday’s opening set could therefore be especially important.
If Shelton serves efficiently and keeps the points short, he can conserve energy while establishing scoreboard pressure. If Tiafoe extends the rallies and forces him through repeated physical service games, the effects of the Alcaraz match could become more visible as the semifinal progresses.
The Arthur Ashe Stadium Factor
Both players possess the personality to embrace the occasion.
Shelton brings visible intensity and emotional fire, while Tiafoe has one of the strongest connections with the New York crowd. With two Americans competing, the atmosphere may shift throughout the match rather than remaining firmly behind one player.
Handling those emotional swings will be crucial.
The danger for both men is allowing the occasion to become bigger than the tennis. There is history available, but the player who concentrates on patterns, service games and individual points will have the better chance of reaching Sunday’s final.
Shelton vs. Tiafoe Prediction
Tiafoe has the experience, variety and defensive skill to make Shelton uncomfortable. He also knows he can defeat Shelton over five sets at the US Open, having done so in 2024.
Shelton, however, enters the semifinal with the more decisive weapons. His left-handed serve can carry him through difficult stretches, and his forehand gives him the ability to take control without having to win extended rallies.
Recovery is the largest concern for Shelton. His victory over Alcaraz finished deep into the night, and Tiafoe will try to make the semifinal as physical as possible.
If Shelton maintains his first-serve percentage and shows the same controlled aggression he produced against Alcaraz, he should generate enough short points to protect his energy. Tiafoe will make him work and could push the match deep into a fourth or fifth set, but Shelton’s serve provides the narrowest of advantages.
Prediction: Shelton to defeat Tiafoe in five sets.
