Ben Shelton has defeated Carlos Alcaraz 6-7 (5), 6-1, 6-3, 1-6, 7-6 (7) in a remarkable five-set quarter-final at the US Open on September 9, securing his first victory against a top-three opponent and reaching the semi-finals. The match concluded at 3:34 a.m. at Arthur Ashe Stadium—the latest finish in the tournament's history—after four hours and 29 minutes, with Shelton holding his nerve through a dramatic fifth set to claim the greatest victory of his career.
Alcaraz, the defending champion and No. 2 seed, arrived at this quarter-final riding an 18-match winning streak at grand-slam level and holding a 31-1 record at the majors since the 2025 French Open. He had advanced to this round by defeating Tommy Paul 6-4, 6-3, 6-4. Yet Shelton, the 23-year-old American and US No. 1, proved a formidable challenger. According to the ATP Tour, Shelton had dispatched Stefanos Tsitsipas in straight sets to secure his third major quarter-final appearance. He arrived at this match with a 12-2 record on hard courts throughout the summer and had captured his second Masters 1000 title in Montreal without surrendering a single set.
The match did not begin until approximately 11 p.m. in New York, after the start of the night session was delayed by earlier matches on September 8. A large crowd remained captivated deep into the night as the modern classic unfolded on Arthur Ashe Stadium, with thousands of spectators still present when the contest concluded at dawn.
How did the match unfold?
Shelton claimed the opening set in a tiebreak after a tightly contested battle, then seized control in the second set by winning nine consecutive games. Alcaraz appeared to have nothing left in the tank as his intensity flatlined and unforced errors mounted. By the time Shelton consolidated a break for a 3-0 lead in the third set, the defending champion seemed destined for defeat.
However, Alcaraz mounted a dramatic comeback. At 5-3 in the third set, he produced one of the points of the tournament, curling a forehand past Shelton before demanding the roars of Arthur Ashe Stadium. Though Shelton held serve to take the set, Alcaraz's resilience had been ignited. He bulldozed through the fourth set, forcing a deciding set at 2:20 a.m., though he spent the final changeover vomiting into his towel, a sign of the physical toll the marathon match was exacting.
In the fifth set, both players showed extraordinary character. At 1-1, Shelton faced a 0-30 deficit but responded with enormous, precise first serves and continued attacking his forehand. He generated three break points at 4-3 but could not convert. Alcaraz held serve and forced a tiebreak. When Shelton earned his next opportunity at 6-6, he did not hesitate. He fired down a 146 mph unreturned serve to lead 7-6, then remained solid from the baseline to reach match point. At 9-7, a 146 mph ace ended the contest as thousands of roaring fans still present until dawn celebrated the upset.
Shelton's dominance in the opening sets reflected his superior execution from the baseline and his commanding serve. He outmuscled Alcaraz from the service line, lashing 145 mph fastballs with ease, and also outfoxed him at net, retrieving Alcaraz's surprise drop shots and countering with impressive volley work. By extending what are ordinarily short rallies for Alcaraz, Shelton forced him to hit extra balls for winners and goaded him into more mistakes. Alcaraz finished with 134 unforced errors across the match—53 of them in total—and struggled with both his serve and return game.
"I made him play a lot," Shelton said afterward. "I didn't worry or stress too much when he hit his spot, hit unreturnable or an ace. I think for me to be able to hang in there in the rallies, have a gameplan from the ground and be able to execute that gameplan and not be losing all the baseline points also helps with the return."
As the pressure mounted in the later sets, Alcaraz showed signs of physical wear, hunching over his racket for support and angrily shooing away a cameraman from his chair. Despite his struggles, he chipped away at Shelton's lethal first strike to give himself 11 break-point chances, converting three. Until this match, Shelton had not been broken in his prior eight sets.
"Obviously when he's serving, he puts a lot of pressure on you,"Alcaraz said afterward, smiling despite the tough loss.
"You're trying to put the return in. It's an unknown if you're going to play the point or [if] he's going to get a free point with his serve. In these moments, he takes a lot of [the] advantage. It's not an excuse, but I would say [his serve] is an important weapon in those moments."
What is the significance of this result?
Shelton's victory marks a watershed moment in his career. He had previously lost all three meetings with Alcaraz, including their most recent encounter at Roland Garros last year where Alcaraz prevailed 7-6 (8), 6-3, 4-6, 6-4. This triumph represents his first victory against a top-three opponent in 17 attempts and proves he can compete with and defeat the sport's highest-ranked players on one of tennis's biggest stages. Before this match, Shelton held a 9-24 record against top-10 players and had never defeated a top-three opponent in 17 previous attempts.
The result also has broader implications for the tournament and American tennis. Alcaraz's defeat means a new US Open champion will be crowned for the first time in 23 years, since Andy Roddick's triumph in 2003. It also marks the first time an American man has won a grand slam tournament in that same span. Shelton, who was not born when Roddick won the US Open, has now guaranteed that an American finalist will compete in the championship match.
The match was part of a historic day of tennis at Flushing Meadows. According to ESPN's live scoreboard, all four men's and women's quarter-final matches extended to deciding sets, with Aryna Sabalenka, Frances Tiafoe and Jessica Pegula each securing spectacular comeback victories. Tiafoe defeated Alex Michelsen in five sets, creating the possibility of an all-American semi-final in the bottom half of the draw.
Shelton's breakthrough carries additional significance for American tennis. A 6ft 4in southpaw with a thunderous serve, he is the best American men's prospect to come along in a generation and represents exactly what commentators had long wished for: a player with the physical tools and competitive drive to contend for major titles. In short order, Shelton progressed from winning a college national championship at the University of Florida to cracking the top 50 in the world to pushing Novak Djokovic in the 2023 US Open semi-finals. This season, Shelton has overtaken Frances Tiafoe, Tommy Paul and Taylor Fritz as the American men's standard bearer while racking up titles on Munich clay and Stuttgart grass and defending his Masters 1000 crown in Canada.
What happens next?
Shelton will face Frances Tiafoe, his compatriot and friend, in the semi-finals on Friday. Shelton enters the semi-final with a 3-1 head-to-head edge over Tiafoe, including a win over him in the 2023 US Open quarter-final that announced Shelton as a force to be reckoned with. The winner will advance to the US Open final, with a once-in-a-lifetime opportunity on the line for both American players. The semi-final matchup guarantees that at least one American will reach the championship match, marking a significant moment for men's tennis in the United States. One of them will become the first Black American man to reach a US Open final since Arthur Ashe in 1972.
