Shelton responds after Alcaraz takes opening tiebreak

Alcaraz made the faster start in a closely contested first set, edging the tiebreak 7-5 to take an early lead. But Shelton responded strongly and shifted the momentum in emphatic fashion during the next two sets.

The American dominated the second set 6-1 before breaking early in the third and taking it 6-3. Shelton’s aggressive play gave him control of the match, with the report highlighting his return positioning and forehand winners as he moved Alcaraz onto the back foot.

Alcaraz, however, was not finished. The defending champion lifted his level in the fourth set and forced the match into a decider by winning it 6-1. His response extended a quarter-final that had already produced major momentum swings and pushed the contest deep into the New York night.

The match was Alcaraz’s first tournament since his four-month layoff, and the report said he appeared rusty at times, failing to reach shots he would usually cover. Although he showed flashes of his best tennis, Shelton continued to press throughout a match that went the full five sets.

A record-setting finish decided by tiebreak

Neither player managed to break serve in the final set, leaving the quarter-final to be settled in a high-pressure tiebreak. The opening and deciding sets were both settled in breakers, underlining how little separated the two players across the late-night contest.

Shelton closed out the final tiebreak 10-7 to complete the upset and claim a major victory over the defending champion. The 3:33 AM conclusion officially set a new mark for the latest finish in US Open history.

For Shelton, the win represents his first victory over Alcaraz and sends him into another Grand Slam semi-final. For Alcaraz, the defeat ends his title defence after a demanding five-set battle in which he recovered from a two-sets-to-one deficit but could not convert the deciding set into a place in the last four.

The quarter-final will be remembered for its length, its changing momentum and its record-breaking finish. Shelton took the biggest moments in the deciding tiebreak, while Alcaraz’s return from injury ended in a narrow defeat on one of the tournament’s most dramatic nights.
