The late-night action at the U.S. Open has now reached an extreme.
Ben Shelton's five-set thriller to beat reigning champion Carlos Alcaraz in the quarterfinals ended at 3:33 a.m. Wednesday, leaving few people awake to see the 4 1/2-hour marathon reach its finale on one of the sport's biggest stages. That only added to the list of early-morning finishes that had already stirred frustration and concerns about how organizers were managing the schedule at the Grand Slam event with numerous matches straying well past night-owl hours.
