Shelton Ends Alcaraz’s U.S. Open Reign in Record-Breaking Night Thriller

Ben Shelton had gone toe-to-toe with Carlos Alcaraz for five exhausting sets and finally, at 3:33 a.m. ET Wednesday, came the chance to end the U.S. Open champion’s title reign.

Shelton fired an ace at 146 m.p.h. – a ball that Alcaraz couldn’t have gotten back even with fresh legs.

That gave Shelton a 6-7 (5), 6-1, 6-3, 1-6, 7-6 (10-7) victory in a marathon tussle that was the latest-finishing match in U.S. Open history.

“I’m tired. It was a war,” Shelton said. “Carlos is one of the greatest champions of our sport. It was the most enjoyable match I’ve had in my career, for sure.”

Alcaraz had his 18-match winning streak in Grand Slam tournaments end in a contest that lasted 4 hours, 28 minutes. He fought deep into the night and early into the next morning in a bid to get his hands on the trophy again, battling back even as he vomited before the start of the final set.

Alcaraz started the year winning the Australian Open, but was playing his first tournament since April after returning from a right wrist injury.

“I’m leaving happy and my head held high,” Alcaraz said. “The truth is, I wanted to win … but also our goal was to leave the tournament having played matches and staying healthy.”

Late-Night Epic Highlights Demands of Modern Grand Slam Tennis

The U.S. Open, organised under the rules of the International Tennis Federation and run as a hard-court Grand Slam fortnight in New York, has long embraced late-night scheduling at Arthur Ashe Stadium to maximise atmosphere, global audiences and broadcast windows.

The Shelton-Alcaraz duel underlined both the appeal and the strain of that model. Thousands stayed to the end, with Arthur Ashe Stadium perhaps still one-third full for the finish. Shelton benefited from a home-crowd boost even against the popular Alcaraz, with fans chanting his name along with “USA! USA!”

“It’s incredible,” Shelton said. “I always say that this is the greatest sports city in the world; I say that this is the greatest stadium in the world. I’m just hoping that my best friend and my sister over there don’t have to be at work at 6 a.m. in three hours.”

For players, such finishes compress recovery time before the next round, particularly in a best-of-five format where physical load accumulates across the fortnight. For the tournament and governing bodies, they sharpen recurring questions around scheduling, competitive fairness and athlete welfare without diminishing the unique night-session identity that sets New York apart from the other majors.

Match at a Glance

• Event: U.S. Open men’s singles quarterfinal, hard court, best-of-five sets
• Venue: Arthur Ashe Stadium, New York
• Result: Ben Shelton def. Carlos Alcaraz 6-7 (5), 6-1, 6-3, 1-6, 7-6 (10-7)
• Duration: 4 hours, 28 minutes
• Finish time: 3:33 a.m. ET – latest-finishing match in U.S. Open history
• Key moment: Shelton closing with a 146 m.p.h. ace on match point

Alcaraz had played in the previous latest finish at the U.S. Open when he outlasted Jannik Sinner in a match that finished at 2:50 a.m. in the 2022 quarterfinals, en route to his first Grand Slam title at 19. That the same player has now been involved in both of the tournament’s latest finishes underscores how central he has become to the current era of the sport and to the night-session product in New York.

Momentum Swings and Tactical Edges

Across five sets, the match’s scoring pattern reflected drastic momentum shifts more than sustained dominance. After Alcaraz edged the opening-set tiebreak, Shelton responded with emphatic wins in the second and third sets, seizing control by winning nine straight games from early in the second set until he had a 3-0 lead in the third.

Alcaraz then forced a decider with a one-sided fourth set, extending the physical and mental demands on both players. In the final-set match tiebreak, he ran off four straight points to go ahead 5-3, appearing to have tilted the contest back in his favour.

Shelton, however, came back behind some of his powerful serves that can exceed 140 m.p.h., along with some mistakes from Alcaraz, and ultimately served out the match with that 146 m.p.h. ace. In a format where a first-to-10 match tiebreak decides the final set, the ability to shorten points and absorb pressure on serve becomes even more decisive, and Shelton’s power game gave him a crucial edge in the final exchanges.

Historic Opportunity for American Men

The Shelton-Tiafoe matchup guarantees a U.S. player will reach the men’s final. The last Grand Slam title for an American man occurred in 2003, when Andy Roddick won the U.S. Open.

In the context of more than two decades without a major men’s singles champion from the United States, this guarantee carries significance beyond a single tournament. It points to a cohort – Shelton, Tiafoe and Alex Michelsen among them – beginning to convert deep runs at Masters-level and major events into sustained relevance in the late stages of Grand Slams.

At the same time, Alcaraz’s exit ensures that a new U.S. Open champion will be crowned. For the sport’s broader competitive balance, that combination – an all-American semifinal on one side of the draw and a field of players on the other side yet to win the title at Flushing Meadows, led by top-ranked Alexander Zverev – reinforces how open this edition has become after years dominated by a small group of multiple major winners.

Three of the four singles quarterfinals went to match tiebreakers on a marathon day, which started with Aryna Sabalenka edging Wimbledon champion Linda Noskova to keep her hopes alive of a third straight U.S. Open title. The density of long matches deep into the second week underlines how margins at the top of the professional game have tightened for both men and women.

Tiafoe Rallies Past Michelsen to Reach Third U.S. Open Semifinal

Shelton, who won his second consecutive Canadian Open title last month, will next play No. 11 seed Frances Tiafoe, who kept coming back until he had reached his third U.S. Open semifinal, beating Alex Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 (10-6).

Tiafoe’s progression reinforces his status as a consistent force in New York. Having already reached the semifinals in 2022, he has again navigated the distinctive pressures of playing as an American contender at home – with expectations, packed night crowds and heavy match loads – to position himself one step from the final.

Michelsen won the first two sets and served with a 5-4 lead in the third, but couldn’t finish it off. He hadn’t lost a set in the tournament until Tiafoe stormed back.

Tiafoe said his performance to start the match was slow and flat.

“It wasn’t good, let’s put it that way. It wasn’t good,” he said. “Three out of five is a blessing, because you have time to get it together. I definitely waited for the last minute.”

Michelsen, ranked No. 46, fell to 0-6 in matches that went to a fifth set. For an emerging player, that record underlines an area of development in closing tight contests over extended distance, even as this run marks a breakthrough in terms of profile and experience at a major.

Shelton-Tiafoe: Styles, Stakes and a Guaranteed American Finalist

The upcoming Shelton-Tiafoe semifinal offers a contrast of styles within a broader American resurgence.

Shelton brings left-handed power, explosive serving and a willingness to take on aggressive shot-making in high-pressure moments, as his tiebreak performance against Alcaraz showed. Tiafoe has built his success on shot variety, speed around the court and an ability to manage momentum over five sets, exemplified by his latest comeback against Michelsen.

Beyond individual narratives, their meeting will decide who carries American hopes into a first men’s singles final at a major since Roddick’s title run in New York. In a field where none of Wednesday’s quarterfinalists on the other side of the draw, led by top-ranked Alexander Zverev, has ever won the Grand Slam at Flushing Meadows, both Shelton and Tiafoe now have a realistic pathway to contend for a career-defining title.

It is also certain that a new U.S. Open champion will be crowned, reinforcing this edition as a potential pivot point: for Alcaraz, a pause in his trajectory of Grand Slam dominance; for the American men, a rare opening; and for the tournament and its organisers, another reminder that the combination of late-night scheduling, best-of-five tennis and a deepening field can produce both spectacle and structural questions that the sport will continue to navigate.
