The Final Score, and How It Unfolded

Ben Shelton emerged victorious over the defending champion with scores of 6-7 (5-7), 6-1, 6-3, 1-6, 7-6 (10-7) in the US Open quarterfinals, in a match that began at nearly 11pm on a Tuesday and extended well until 3:33 am on Wednesday, September 9, marking the latest finish in the tournament’s history. Providing the spectators thrilling rounds of tennis, the match kept swinging widely towards both the challengers, with Alcaraz winning the opening set in a tiebreak, only for Shelton to make a comeback and go onto win nine straight games spanning the second and third sets to obtain a 2-1 lead. With a brilliant display showing why he’s the sport’s two-time defending champion, Alcaraz was quick to fight back and leveled things with a 6-1 dominant fourth set that was followed by a decisive fifth set that both competitors fought hard for.

The final and deciding set remained deadlock in a final-set tiebreak for a while, but both displayed their dominance with Alcaraz racing ahead with a 5-3 lead initially before Shelton returned to swing the sides to a 10-7 scoreline. Shelton closed the match, and the record, with a 146 mph serve that Alcaraz simply couldn't find an answer for.

A Record That Took Four Hours and 28 Minutes

The match extended for a duration of four hours and 28 minutes in total, and its 3:33 am finish just narrowly brushed ahead of the previous record of latest finish in the US Open History, the record being held from 2022 quarterfinal where similarly, Alcaraz had won over Janik Sinner with the match ending at 2:50 a.m, and paving his path to his first Grand Slam title at only 19 years of age. And if the records are to be considered, there’s a certain symmetry in watching history repeat itself as Alcaraz was caught on the losing end of the very record he himself had previously set on a late New York night just a couple of years ago. Notably, the Arthur Ashe Stadium continued to echo with the chants of thousands of fans that stayed through the morning hours chanting Shelton's name alongside the "USA! USA!" slogans out loud, a remarkable energy that sustained throughout the memorable night.

The Moment That Decided It

The nearly four-and-a-half-hour battle was truly a test of both amazing players, taking a physical toll that no one could’ve anticipated or prepared for. During a moment of the match, Alcaraz having recently recovered from a wrist injury and playing his first competitive tournament since April was also observed vomiting into a towel courtside having been exhausted from the enduring battle. Shelton on the other hand, remained consistent in dealing hard blows through his sheer raw power with continuously serving balls in paces that exceeded 140mph before reaching the peak pace of 146 mph that truly sealed the victory. Addressing the exhaustion and endurance of the match, Shelton following the match claimed that it nearly felt like a war while acknowledging the place of Carlos Alcaraz amongst the greatest champions of the sport and being grateful about having competed in the most enjoyable match of his career.

What It Means for Alcaraz

The quarterfinal loss to Ben Shelton, unfortunately brought a conclusion to Alcaraz’s US Open title defense while also breaking a significant 18-match winning streak across Grand Slam tournaments. Alcaraz has also otherwise struggled this season, having missed both Wimbledon and the French Open following his latest injury, while he did claim the Australian Open title earlier in the year. Alcaraz continues his boxing career with a 15-2 in five-set matches for his career, Alcaraz presents himself as an immovable force that no one dares to challenge, but Shelton simply refused to accept that reality and found the strategy to carve the name for the history books.

What It Means for Shelton — and American Tennis

Emerging victorious on the thrilling night became historic for Shelton far beyond the record-setting finish time. The victory also marked the first time he had defeated a top-three player, having entered the match with a tally of 0-17 against top-three opponents throughout his career while also being his first-ever top seed at a Grand Slam. Shelton also became the first American to beat a defending US Open Champion in five sets since 1989 where an 18-year old Pete Sampras defeated Mats Wilander.

Shelton’s victory also set up the perfect outcome for American men’s tennis, since his semi-final now set against fellow American Frances Tiafoe, ensuring that at least one US finalist will continue onto the Sunday’s men’s championship final, something that the country hasn’t seen since 2003. And with the likes of Alcaraz, Novak Djokovic, and Jannik Sinner being out of the draw, it sets up to be the perfect opportunity for an American Man to rise up and take the reins and end the American drought.

The Wider Night: A Marathon Day at Flushing Meadows

Amongst the many remarkable demonstrations that became part of the historic night, Three of the four men's singles quarterfinals went to deciding tiebreaks on what became a genuinely grueling day at Flushing Meadows. Frances Tiafoe, the No. 11 seed, recovered from two sets down and came back to win from a 0-3 deficit in the decisive fifth set to beat fellow American Alex Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 (10-6), and in turn, set up the historic all-American semifinal against Shelton. On the women's side, Aryna Sabalenka edged Wimbledon champion Linda Noskova earlier in the day to keep alive her bid for a third consecutive US Open title.

What's Next

Shelton now faces Tiafoe in Sunday's men's semifinal, with the winner guaranteed a place in the final and a genuine shot at becoming the first American man to win a Grand Slam singles title since Roddick's 2003 US Open triumph. And with Shelton performing at his finest with pure pace and determination, this competition could well be leading up to a moment that American tennis fans have been awaiting for more than two decades!

Conclusion

The match between Shelton and Alcaraz is sure to become etched into the minds of many viewers as one of the most historic nights that the sport has recently seen, not because it continued deep into the night but more because it was an absolute demonstration of pure skill and sheer commitment to not going down without a fight. Alcaraz ensured to give everything he had, fighting back through physical exhaustion until he truly had nothing left to give. Sheldon, simply edged past in the match-up, marking his place onto the semi-finals and his eyes onto the larger prize and glory that awaits him in winning the US Open 2026 Title. And regardless of whatever happens in Sunday's final, September 9 already belongs to both Shelton and Alcaraz, to one perhaps for how much he had lost and for the other, how much he had given and still had left at 3:33 in the morning.
