Ben Shelton delivered the finest performance of his career to eliminate Carlos Alcaraz from the US Open in a historic five-set thriller that concluded in the early hours of the morning in New York. The quarter-final match finished at 3:34 local time, setting a new record for the latest-ever completion in the history of the Flushing Meadows tournament.

A dedicated audience stayed inside Arthur Ashe Stadium to witness a modern classic that stretched across four hours and 28 minutes of unpredictable tennis. Play did not get underway until approximately 11:00 p.m. because preceding matches on the schedule pushed back the start of the night session.

The eighth-seeded American celebrated the biggest victory of his professional journey to equal his career-best performance at a Grand Slam event. Prior to this encounter, Shelton had failed to win any of his 17 matches against top-three opponents and had suffered three previous defeats to the Spanish star.

The result keeps alive the possibility of crowning the first American men's singles champion at the tournament in over two decades. Shelton, who was not yet born when Andy Roddick secured the title in 2003, will now face compatriot Frances Tiafoe in the semi-finals, ensuring an American representative in the championship match.

Alcaraz entered the tournament following a lengthy absence from the sport due to a wrist injury that sidelined him for more than four months. Despite limited preparation, the two-time major champion exceeded expectations by reaching the quarter-finals, including a straight-sets win over Tommy Paul in the previous round.

Signs of fatigue began to emerge as the physical contest wore on through a series of breathless exchanges and athletic rallies. Even so, Alcaraz refused to yield, battling back to force a deciding fifth set and pushing the contest into a tense 10-point match tie-break.

Shelton ultimately prevailed with a final score of 6-7, 6-1, 6-3, 1-6, 7-6, sealing the triumph in the tie-break by a 10-7 margin. The exhausted winner received a standing ovation from the remaining spectators as the historic session finally drew to a close.
