The clock read 3:33 a.m. in Queens on Wednesday morning when Ben Shelton fired a 146 mph ace past Carlos Alcaraz to settle the latest-finishing match in U.S. Open history. Thousands of fans remained in the stands at Arthur Ashe Stadium to watch the conclusion of a five-set quarterfinal thriller that lasted four hours and 28 minutes.

How Shelton Overturned the Defending Champion
Alcaraz took the opening set in a tight tiebreaker, but Shelton seized control by winning nine straight games spanning from early in the second set to a 3-0 lead in the third. Alcaraz, playing in his first tournament since April following a four-month layoff due to a right wrist injury, dug deep despite vomiting before the start of the final set.

In the deciding fifth set, neither player broke serve, forcing a 10-point tiebreaker. Alcaraz surged ahead 5-3 in the tiebreaker before Shelton reeled off the closing points, sealing the match with his booming serve.
“Carlos is one of the greatest champions of our sport. It was the most enjoyable match I’ve had in my career, for sure.”

Shelton acknowledged the role of the partisan New York crowd, where spectators chanted his name and shouted “USA! USA!” until the final point.
“It’s incredible, I always say that this is the greatest sports city in the world … that this is the greatest stadium in the world. I’m just hoping that my best friend and my sister over there don’t have to be at work at 6 a.m. in three hours.”
