Taylor Fritz US Open Run Ends in Stunning Collapse

The Taylor Fritz US Open campaign ended in one of the most dramatic collapses of the 2026 tournament, as the American surrendered a two-set lead before falling to Argentina’s Francisco Cerundolo in five sets.

Fritz appeared firmly in control on Arthur Ashe Stadium after taking the opening two sets 6-3, 6-4. He was also ahead by a break early in the third set, putting himself within touching distance of the fourth round.

Instead, Cerundolo produced a remarkable turnaround.

The 24th-seeded Argentine won the final three sets 6-3, 6-4, 6-4 to complete a 3-6, 4-6, 6-3, 6-4, 6-4 victory. The result sent Fritz out in the third round and delivered one of the biggest upsets of the men’s tournament so far.

For Fritz, the defeat was especially painful because he had entered the tournament with genuine hopes of making another deep run in New York.

Taylor Fritz US Open Exit Comes After Dominant Start

The contrast between the beginning and ending of the match was striking.

Fritz entered the third-round contest as the No. 9 seed and one of the leading American contenders. He had reached the US Open final in 2024 and was widely viewed as one of the players capable of challenging for the title in a men’s draw that had opened considerably.

His first two matches in New York had reinforced that belief.

Fritz defeated fellow American Darwin Blanch in straight sets in the opening round before producing an even more impressive performance against Italy’s Mattia Bellucci. He dismantled Bellucci 6-0, 6-1, 6-1 in just 98 minutes, arriving at the Cerundolo match without dropping a set.

That form continued at the beginning of the third round.

Fritz controlled the baseline exchanges, found his range with his forehand and made Cerundolo work for virtually every service game. The American claimed the first set 6-3 and followed it with another 6-4 set to establish a commanding advantage.

At that point, the match appeared to be following a familiar script: Fritz was moving toward another fourth-round appearance while Cerundolo faced an increasingly difficult task.

But the Argentine refused to disappear.

Cerundolo Finds the Turning Point

The decisive change came in the third set.

Cerundolo began to take more initiative in the rallies and stopped allowing Fritz to dictate points so consistently. His forehand became increasingly dangerous, while his movement and defensive work forced Fritz to hit additional shots.

The Argentine eventually turned the momentum around and took the third set 6-3.

From there, the match became a completely different contest.

Cerundolo’s confidence continued to rise, while Fritz struggled to reproduce the level he had shown during the opening two sets. The American’s frustration became increasingly visible as opportunities disappeared.

Cerundolo took the fourth set 6-4, sending the match into a deciding fifth set.

For a player making his first appearance on Arthur Ashe Stadium at the US Open, the Argentine showed remarkable composure.

Rather than being overwhelmed by the occasion, Cerundolo embraced it.

He continued to attack, defended effectively when necessary and maintained enough discipline to prevent Fritz from regaining complete control.

The fifth set ultimately followed the same pattern. Cerundolo won 6-4, completing a comeback that had looked extremely unlikely less than two hours earlier.

Taylor Fritz Struggles as Momentum Shifts

For Fritz, the most difficult aspect of the Taylor Fritz US Open defeat was how quickly the match changed.

He had done much of what was required during the opening stages. His serve gave him free points, his groundstrokes were penetrating and he was consistently pushing Cerundolo behind the baseline.

But once Cerundolo raised his level, Fritz struggled to regain the same control.

The American also missed opportunities that could have changed the direction of the contest. Instead of closing the match while ahead, he allowed Cerundolo to remain close enough to build belief.

That belief became a major factor.

After winning the third set, Cerundolo looked increasingly comfortable. Fritz, meanwhile, appeared to be searching for answers as the Argentine continued to extend rallies and attack the American’s weaker moments.

ATP Tour coverage described Fritz’s reaction afterward as one of disbelief, with the American acknowledging just how difficult it was to explain how the match had escaped him.

A Painful Result for American Tennis

Fritz’s loss was not only significant for his individual season.

It also represented a major setback for American men’s tennis.

Fritz had been one of the most prominent American hopes of ending the country’s long wait for a men’s Grand Slam singles champion. American men have not won a major singles title since Andy Roddick captured the 2003 US Open.

The pressure surrounding that drought was particularly relevant in New York.

Fritz had already demonstrated that he could handle the spotlight. His run to the 2024 US Open final established him as a serious Grand Slam contender, even though he ultimately lost the championship match.

The 2026 tournament appeared to offer another opportunity.

Several established stars were absent or had already departed, creating a more open draw. Fritz’s dominant first two rounds only increased expectations.

Instead, his tournament ended before the second week.

Reuters noted that Fritz’s defeat was his earliest US Open exit in four years and that only four of the tournament’s top 10 seeds remained after the third-round action.

Cerundolo Completes a Career-Defining Comeback

While the result was devastating for Fritz, it represented a major breakthrough for Cerundolo.

The Argentine entered the tournament as the No. 24 seed and had already established himself as a dangerous player on the ATP Tour. Earlier in 2026, he won the Queen’s Club title, the biggest trophy of his career at the time. That victory made him the first Argentine to win the prestigious London tournament.

His comeback against Fritz demonstrated another part of his game: resilience.

Cerundolo had every reason to feel discouraged after losing the first two sets and falling behind early in the third. Instead, he gradually changed the match through increased aggression and improved consistency.

His reward is a place in the fourth round.

He will face Belgian Alexander Blockx, who also produced a notable upset by defeating fifth seed Flavio Cobolli.

The opportunity is enormous.

A deep run in New York could transform what has already been an important season for Cerundolo into the biggest campaign of his career.

The Match Changes the US Open Picture

The Taylor Fritz US Open defeat also adds another layer of uncertainty to an already unpredictable men’s draw.

Fritz was one of the players many observers expected to take advantage of the open field. His elimination means another potential title contender has disappeared before the fourth round.

Cerundolo himself described the men’s tournament as unusually open.

That assessment is supported by the number of unexpected results. Several high-profile players have already exited, leaving a field in which opportunities are available to players who may not have been considered primary favorites before the tournament began.

For fans, that unpredictability has made the 2026 US Open particularly compelling.

A tournament that initially appeared to revolve around a small group of established names has quickly developed into a much wider competition.

Fritz’s Summer Had Offered Plenty of Promise

The US Open loss should also be viewed against the wider context of Fritz’s 2026 season.

The American had shown strong form during the summer, most notably by winning the Mubadala DC Open in Washington in August.

That title was Fritz’s 11th ATP Tour trophy and his first title above the ATP 250 level in nearly four years. He defeated Rafael Jodar in the final and displayed the type of serving and baseline consistency that had made him such a dangerous hard-court player.

That success helped build momentum heading into New York.

His opening-round performances then suggested that momentum had carried over.

But Grand Slam tennis is ultimately decided by individual matches, and against Cerundolo, Fritz could not finish the job after establishing a commanding advantage.

The defeat does not erase the progress he made during the season. However, it does raise questions about how he will respond to another painful Grand Slam setback.

What Comes Next for Taylor Fritz?

The immediate challenge for Fritz is recovery.

Physically, a five-set match is demanding. Mentally, surrendering a two-set lead can be even more difficult.

The American now has to move beyond one of the most frustrating defeats of his season and prepare for the remainder of the ATP calendar.

The key issue will be whether Fritz can turn the experience into a lesson rather than allowing it to become a lingering source of doubt.

He has already demonstrated that he belongs among the best players in men’s tennis. His US Open final appearance in 2024 and his strong 2026 results provide evidence of that.

However, the next step in his development is converting strong positions into major victories.

Against Cerundolo, he had the match exactly where he wanted it.

He simply could not close it.

A New Opportunity for Cerundolo

For Cerundolo, the situation could hardly be more different.

He leaves the match with enormous momentum and growing belief.

Coming back from two sets down on Arthur Ashe Stadium is the kind of victory that can change a player’s perception of himself. It also changes how opponents view him.

Cerundolo now enters the fourth round with the knowledge that he can survive against one of the tournament’s strongest home favorites even after falling deep behind.

His next opponent, Blockx, will present a different challenge.

But after the comeback against Fritz, Cerundolo has every reason to believe that another breakthrough is possible.

Taylor Fritz US Open Loss Highlights the Tournament’s Unpredictability

Ultimately, the Taylor Fritz US Open exit is a reminder of how quickly momentum can change at a Grand Slam.

Fritz appeared unbeatable for two sets.

Cerundolo looked close to elimination.

Then everything changed.

The Argentine’s 3-6, 4-6, 6-3, 6-4, 6-4 victory was not simply an upset. It was a demonstration of resilience, tactical adjustment and mental strength under extreme pressure.

For Fritz, the loss will be difficult to accept because of what was at stake and how close he came to advancing.

For Cerundolo, it could become the defining victory of his 2026 season.

And for the US Open, it is another sign that there may be no safe path through this year’s men’s draw.

The American title hopes are still alive through other players, but one of the tournament’s biggest home favorites is gone.

Taylor Fritz will leave New York wondering how a match he controlled for two sets slipped away.

Cerundolo, meanwhile, will continue his run with something even more valuable than a fourth-round berth: belief that he can beat anyone when the pressure is at its highest.
