How Shelton turned the match after losing the first set

Alcaraz took the opening set in a tiebreak, but Shelton changed the match quickly. He won nine straight games across the second and third sets, using his first-strike power on serve while also attacking Alcaraz’s second delivery and finishing points with sharper angles from the baseline.

The second set was the clearest swing. Shelton broke early, protected his own serve and raced through the set 6-1. He carried that pressure into the third, where he broke again and won 6-3. The pattern mattered because Shelton had struggled to break Alcaraz in their earlier meetings. In New York, he finally created repeated pressure in return games instead of depending on tiebreaks alone.

Alcaraz responded like a defending champion in the fourth set. He increased the depth of his returns, broke Shelton three times and took the set 6-1, forcing a decider. That reset the contest before the fifth set became a test of serving under pressure, patience in longer rallies and nerve in the final match tiebreak.

The fifth-set tiebreak decided a match that refused to settle

Neither player gave the other a clean route through the deciding set. Shelton had to save break points and Alcaraz continued to push him into extended exchanges, but the American kept enough first serves in play to reach the 10-point match tiebreak. Shelton eventually won it 10-7, finishing with the 146 mph ace that sealed the upset.

Why the win matters for Shelton

The result is Shelton’s first victory over a player ranked inside the top three and his first win over Alcaraz. It also made him the first American man to defeat Alcaraz at a major, according to the US Open’s tournament statistics.

Shelton had already shown he could make a deep run in New York when he reached the semifinals in 2023. This victory carries more weight because of the opponent, the pressure of the final set and the way Shelton won. He did not rely on serve speed alone. He returned aggressively, survived longer exchanges and recovered after being dominated in the fourth set.

The quarterfinal also entered the tournament record book because of when it ended. The final point came at 3:33 a.m., later than any previous US Open match finish. The unusual schedule became part of the story as both players had to manage fatigue while maintaining a high level deep into the deciding set.

The US Open later highlighted the match as one of the defining contests of the day and published a collection of video highlights. Watch the official US Open highlights.

The rally that had the crowd on its feet

Before the final-set drama, the match had already produced one of the tournament’s standout points. In the third set, Shelton and Alcaraz covered the full court through a long, high-speed exchange before Alcaraz finished with a backhand volley. ESPN clipped the point after the crowd rose in response.

What comes next: Shelton vs Frances Tiafoe

Shelton will face Frances Tiafoe in the semifinals after Tiafoe came back from two sets down to beat Alex Michelsen in five sets. The matchup guarantees an American man in the US Open final for the first time since 2003, according to tournament coverage.

For Shelton, the challenge now changes. Against Alcaraz, he could play as the lower-ranked underdog with little to lose. Against Tiafoe, the matchup carries a different kind of pressure because both players know each other well and the winner will play for the title.

How the upset reshapes the men’s draw

Alcaraz’s defeat removes the defending champion from the field and guarantees a new men’s champion in New York. It also adds to a tournament already shaped by major early surprises.

Earlier in the event, Mariano Navone eliminated Novak Djokovic in the first round. Factelle covered that result in its report on Djokovic’s shock US Open exit, another result that opened the men’s draw.
