The Spanish teenager needed five sets and more than five hours to reach the semifinals in a match that ended shortly before 3 a.m. in New York.
It was the latest finish ever at the U.S. Open, played in a city that purportedly never sleeps, but Carlos Alcaraz and Jannik Sinner made it well worth staying up into the wee hours.
In one of the best (and longest) matches ever contested at this Grand Slam tournament in New York, Alcaraz, a 19-year-old Spanish prodigy, fought off a match point in the fourth set to defeat Sinner, a 21-year-old Italian prodigy, 6-3, 6-7 (7), 6-7 (0), 7-5, 6-3, to advance to the semifinals.
