Alcaraz's US Open Title Defense Comes to an End

Carlos Alcaraz's attempt to defend his US Open crown is over after the Spaniard was beaten by Shelton in one of the most dramatic matches of the tournament.

Alcaraz entered the quarterfinal as one of the leading contenders for the championship, having already moved through the opening rounds with wins over Roman Safiullin, Jaime Faria, Yibing Wu and Tommy Paul.

But Shelton presented an entirely different challenge. The American's powerful serve, aggressive baseline game and ability to attack short balls repeatedly put pressure on the defending champion.

After more than four hours of tennis, Shelton finally delivered the decisive blow.

Shelton Takes the Opening Blow and Fights Back

The opening set was extremely competitive, with neither player able to create a decisive separation.

Alcaraz eventually edged Shelton in the tiebreak, taking the first set 7-6(5) and moving one step closer to another US Open semifinal.

For Shelton, however, losing the opening set did not lead to a collapse. Instead, the American responded with arguably his best stretch of tennis in the match.

He immediately raised his level and began putting Alcaraz under sustained pressure from the baseline.

Shelton Turns the Match Around

The second set belonged completely to Shelton.

The American attacked relentlessly and took advantage of opportunities on Alcaraz's serve, racing through the set 6-1 to level the momentum of the contest.

Shelton continued his aggressive approach in the third set. Alcaraz struggled to regain the control he had shown earlier, while Shelton remained composed and continued to dictate points.

The American eventually won the third set 6-3, leaving Alcaraz one set away from elimination.

The turning point: Shelton responded to losing the first-set tiebreak by winning the next two sets 6-1, 6-3 and completely changing the direction of the match.

Alcaraz Refuses to Go Quietly

With his US Open title defense hanging by a thread, Alcaraz produced a remarkable response in the fourth set.

The Spaniard regained his attacking rhythm and immediately put Shelton under pressure. His movement improved, his groundstrokes became more consistent and he began controlling rallies once again.

Alcaraz raced through the fourth set 6-1, forcing the match into a deciding fifth set.

After Shelton had looked firmly in control, the contest was suddenly back to level terms and everything came down to one final set.

Everything Comes Down to the Final-Set Tiebreak

The deciding set delivered exactly the drama expected from a Grand Slam quarterfinal between two of the biggest names in men's tennis.

Neither player was willing to surrender the crucial advantage. Shelton continued searching for opportunities with his powerful serve, while Alcaraz fought to keep his title defense alive.

The set ultimately went to a deciding tiebreak, putting the entire match on the line.

Shelton then produced the biggest moments of his tournament. He remained aggressive under pressure and eventually secured the deciding breaker 10-7.

Final score: Ben Shelton defeated Carlos Alcaraz 6-7(5), 6-1, 6-3, 1-6, 7-6(10-7).

Ben Shelton Reaches the US Open Semifinals

The victory sends Shelton into the US Open semifinals and gives the American one of the biggest wins of his career.

His path to the final four has already included victories over Hubert Hurkacz, Denis Shapovalov and Stefanos Tsitsipas before his stunning defeat of Alcaraz.

Now Shelton has the opportunity to go even further in New York.

The American will face fellow countryman Frances Tiafoe in the semifinal after Tiafoe completed his own remarkable comeback against Alex Michelsen.

A Huge Night for American Tennis

Shelton's victory adds another major chapter to an impressive US Open campaign for American men's tennis.

Frances Tiafoe had already secured his semifinal place by defeating Alex Michelsen in five sets, meaning the United States is guaranteed a men's singles finalist at this year's tournament.

The semifinal between Shelton and Tiafoe will now become one of the most anticipated matches of the tournament, with both Americans one victory away from reaching the US Open final.

What Alcaraz's Exit Means for the Title Race

Alcaraz's elimination completely changes the complexion of the 2026 US Open men's singles title race.

The defending champion had been one of the tournament's biggest favorites, but his defeat means a new champion will be crowned in New York this year.

Shelton's victory also opens an enormous opportunity for the remaining players in the draw. With Alcaraz gone, the path to the trophy has become considerably more open.

For Shelton, however, the focus will be much simpler: recover from another marathon battle and prepare for an all-American semifinal against Tiafoe.

Shelton Has a Chance to Make History

Beating Alcaraz is one achievement. Turning that victory into a place in the US Open final would be another entirely.

Shelton now has the opportunity to build on the biggest win of his tournament and potentially reach his first Grand Slam final.

Standing in his way is Tiafoe, another American who knows exactly what it takes to produce memorable performances in New York.

After surviving Alcaraz in a five-set classic, Shelton is now just two victories away from lifting the US Open trophy.
