Carlos Alcaraz’s 2026 US Open campaign ended in one of the most physically demanding matches of the tournament. The defending champion was beaten by Ben Shelton in a five-set quarterfinal

that lasted four hours and 28 minutes and concluded at 3:33 a.m. New York time, producing the latest finish in tournament history.

The final score, 6-7, 6-1, 6-3, 1-6, 7-6, reflects how closely the contest was fought. Alcaraz took the opening set, struggled significantly during the second and third, responded strongly in

the fourth, and then competed until the final points of the deciding tiebreak. Shelton eventually prevailed 10-7 in the final breaker.

For Alcaraz, the result has to be considered within a much broader physical context. The Spaniard had not played a competitive match for roughly four and a half months because of a right wrist injury.

His return to a Grand Slam therefore represented more than another tournament appearance; it was his first serious examination of how his body would respond to sustained competition.

Before the tournament began, Alcaraz openly acknowledged that returning to competition after such a long absence felt unfamiliar. After his opening match, he explained that he had even struggled to remember parts of his usual match-day routine.

He also admitted to feeling more nervous than normal because he did not know exactly how his body and mind would respond.

That admission provides important context for the later loss. Elite tennis players can train extensively during rehabilitation, but competitive matches create a different physiological and psychological demand. The intensity of repeated rallies, changes of direction, serving under pressure and emotional swings cannot be perfectly reproduced away from official competition.

Alcaraz nevertheless began the tournament convincingly. He defeated Roman Safiullin in straight sets and subsequently continued through the draw without dropping a set in the early rounds. His movement appeared strong, and his level gradually improved as he accumulated competitive minutes after the lengthy interruption.

There were signs, however, that his return was still a work in progress. Against Yibing Wu, Alcaraz produced 33 unforced errors but still controlled the match comfortably. His movement remained impressive, while his serve provided enough stability to prevent the Chinese player from turning those inconsistencies into serious danger.

His comments during the tournament were also revealing. Rather than focusing exclusively on winning the title, Alcaraz repeatedly emphasized the importance of staying healthy and seeing how his body responded to competition.

That approach suggested that his team understood the US Open as an important stage in the rehabilitation process rather than simply another tournament to dominate.

Against Ben Shelton, the physical demands eventually became much greater. The match repeatedly shifted direction, forcing both players to produce high-intensity tennis for more than four hours. By the end

of the third set, Alcaraz acknowledged that he was physically tired, although he subsequently recovered enough to produce a strong fourth set and remain competitive.

There was also a visible moment of physical distress during the match when Alcaraz appeared to vomit into a towel. Reports from the court described the episode as part of

an extremely demanding contest, while the match itself continued into the early morning hours. The incident should not automatically be interpreted as evidence of a new medical condition.

The timing of the match adds another dimension to the discussion. The contest began at 11:04 p.m. and finished at 3:33 a.m., making it the latest completed match in US Open history.

The unusual schedule has generated broader discussion about player recovery and whether matches of such intensity should be allowed to finish so deep into the night.

From a performance perspective, however, Shelton deserves substantial credit. His serve became an increasingly influential weapon as the match progressed, particularly in important moments. Alcaraz himself identified the American’s serve

as one of the decisive factors because it could produce free points or immediately place pressure on the returner in critical situations.

Shelton also demonstrated tactical maturity. Rather than becoming discouraged after losing the fourth set, he maintained his aggressive approach and continued making Alcaraz work for points. His returning was effective enough to prevent the Spaniard from controlling the match through his usual combination of power, movement and variation.

The deciding set illustrated the narrow margins between two elite competitors. Alcaraz managed to recover physically and improve as the match progressed, while Shelton maintained enough serving quality and composure to take the final tiebreak.

The outcome was therefore not simply a case of one player collapsing physically; it was a contest in which both players had to solve difficult problems repeatedly.

That distinction is important when assessing Alcaraz’s performance. A defeat after such a long absence does not necessarily indicate that his level has deteriorated. On the contrary, reaching the quarterfinals immediately after returning from a lengthy wrist injury demonstrated that his competitive foundation remained extremely strong.

The four-hour, 28-minute battle also provided information that training sessions could not. Alcaraz experienced long rallies, pressure situations, momentum changes and the physical consequences of repeated sets. Those experiences can

be valuable for his team when planning the remainder of the season and determining how much workload he can safely handle.

After the match, Alcaraz did not frame the result as a personal failure. Instead, he said he was happy and proud of the way he fought. He also emphasized that

he left the court healthy, which was particularly significant given that this was his first Grand Slam tournament after the wrist injury.

His response showed a degree of perspective that is often difficult to maintain after a painful defeat. For a defending champion accustomed to deep runs at major tournaments, losing in the quarterfinals can naturally feel disappointing. Yet Alcaraz appeared to understand that the circumstances surrounding this particular tournament were different.

The psychological side of returning from injury should also not be overlooked. Players often need time to rebuild confidence in specific movements, particularly when the injured area is involved in almost every important stroke.

For a player whose forehand and serve rely on rapid acceleration and precise wrist control, returning to full competitive trust is a gradual process.

Alcaraz’s own statements before the tournament suggested exactly that. He said he wanted to compete, enjoy being back on court and see how his body reacted after matches. He also

acknowledged that he did not know how far he would progress. Those comments now appear particularly reasonable given the physical test he ultimately faced against Shelton.

The defeat also highlights the changing competitive landscape of men’s tennis. Shelton, 23, entered the match with considerable expectations but had never previously reached the semifinals of the US Open.

His victory over Alcaraz represented an important step in his development and gave American men’s tennis another major storyline at the tournament.

For Alcaraz, meanwhile, the loss ended an 18-match Grand Slam winning streak. That statistic demonstrates how high his level had been before the defeat, but it should not obscure the circumstances of the current season.

His objective now should be to convert the lessons from New York into a sustainable return rather than rushing to prove that he remains unbeatable.

There is also a wider scheduling issue that deserves attention. The match ended when most fans would normally be asleep, while the players had spent more than four hours competing at extraordinary intensity.

Several players and commentators have questioned the frequency of extremely late finishes at the US Open, raising concerns about recovery and the overall working conditions for athletes.

For Alcaraz specifically, the timing was particularly demanding because he was already managing the workload associated with his return. Playing until 3:33 a.m. after beginning at 11:04 p.m. meant that recovery from the match itself became another challenge. Nevertheless, there is no evidence that the schedule alone caused his defeat.

The match should instead be viewed as a combination of factors. Shelton produced excellent tennis, Alcaraz experienced physical fatigue, the contest lasted more than four hours and the Spaniard was

still rebuilding competitive rhythm after months away. These elements interacted throughout the evening rather than producing a single explanation for the final result.

It is also important not to transform isolated physical moments into unsupported claims about Alcaraz’s private life or health. There has been no verified announcement that he concealed a major personal problem

from the public or that an undisclosed condition directly caused his defeat. The confirmed information concerns his previous wrist injury, physical fatigue during the match and the extraordinary demands of the contest.

That distinction matters because professional athletes are frequently evaluated through short clips and social-media reactions. A difficult moment captured by a camera can quickly become the basis for speculation. Yet elite performance is much more complicated than a single image, particularly in a four-and-a-half-hour match played deep into the night.

Alcaraz himself provided the most useful interpretation after the match. He credited Shelton, described the American as an exceptional and powerful opponent, and refused to use his physical condition as an excuse.

His comments were consistent with the attitude he had shown throughout the tournament: compete seriously, protect his health and learn from the experience.

There was particular significance in his statement that he felt better and better during the fifth set. That suggests that although fatigue affected him during the middle stages, he was

able to recover sufficiently to compete for the match until the final tiebreak. From a rehabilitation perspective, that competitive resilience may ultimately prove more valuable than the result itself.

The next stage of Alcaraz’s season should therefore be approached with patience. He does not need to prove immediately that he can reproduce the form that made him a Grand Slam champion.

What matters is rebuilding a consistent competitive rhythm while maintaining the health of the wrist and allowing his body to adapt to the demands of regular tournament play.

His team will have considerable information to analyze from New York. They can assess how the wrist responded across multiple matches, how his physical condition changed during long contests, and

where his tennis still differs from the level he showed before the injury. Such analysis can help shape the remainder of the season.

For fans, the most encouraging aspect may be that Alcaraz was capable of producing high-level tennis again. He reached the quarterfinals immediately after a lengthy absence, won multiple matches, competed

for more than four hours against one of the strongest young players in the draw and remained physically capable of fighting until the final point.

That does not mean his return is complete. A Grand Slam quarterfinal is a strong result, but consistency over several months will provide a much better measure of whether he has fully recovered.

The transition from rehabilitation to sustained competition is rarely immediate, especially for a player whose game depends so heavily on speed, explosiveness and constant changes of direction.

The defeat against Shelton therefore carries a more nuanced meaning than a simple failure to defend the title. It was the first major examination of Alcaraz after a significant interruption,

and it exposed both his remaining physical challenges and his ability to compete through them. The result was disappointing, but the broader evidence was far from negative.

It is equally important to recognize Shelton’s achievement without diminishing Alcaraz’s effort. The American did not simply benefit from his opponent’s fatigue. He served effectively, returned intelligently, maintained his composure

and found solutions during crucial moments. His victory was the product of his own performance as much as the circumstances surrounding Alcaraz.

The mutual respect shown afterward reinforced that perspective. Alcaraz congratulated Shelton and acknowledged the quality of his performance, while Shelton praised Alcaraz as one of the great champions of the sport despite being only 23 himself.

Their reactions reflected the competitive standard of the match rather than the online narratives that often follow a major upset.

Ultimately, the most responsible conclusion is that Carlos Alcaraz leaves New York with questions to answer but also reasons for optimism. His wrist allowed him to compete again, his tennis

reached a high level at several points, and his physical resilience was tested under extreme circumstances. Those are meaningful foundations for the next stage of his career.

The quarterfinal defeat will remain a significant moment because of the opponent, the five-set battle and the historic finishing time. Yet it should not become a definitive judgment on Alcaraz’s form or future.

After four and a half months away, the more important story is that he returned to Grand Slam competition, fought until the final point and emerged ready to continue building his season.
