Ben Shelton dethrones Carlos Alcaraz in five-set thriller after latest US Open finish

• Winner claims 6-7 (5), 6-1, 6-3, 1-6, 7-6 (7) victory

• Epic quarter-final ends after 3.30am in New York

As the official 10th day of play in New York moved deeper into the remote hours of the new morning, every passing game imbued Carlos Alcaraz with greater despair. From his focused start, Alcaraz's intensity had flatlined and he could barely put a ball in court. He lost nine consecutive games against Ben Shelton and seemed to have nothing left.

Instead, the defending champion improbably dragged himself back into a contest that soon developed into one of the most remarkable matches of the year. The latest attempt by Alcaraz, the second seed, at orchestrating a monumental comeback was denied by a brave, defiant Shelton, the eighth seed, who refused to be shaken by his legendary rival or the looming prospect of securing the greatest win of career.
