Ben Shelton is now 13/8 to win the US Open after he dumped world number three Carlos Alcaraz OUT of the competition in an epic quarter-final clash.
More than four-and-a-half hours of play was needed to separate the two, with the American eventually wrapping up a 6-7, 6-1, 6-3, 1-6, 7-6 success at 03:33 local time - the latest finish to a match in the competition's history.
Francis Tiafoe now awaits Shelton in a highly-anticipated semi-final clash; America guaranteed just their second home Men's US Open finalist in 20 years.
Taylor Fritz suffered an agonising defeat to Jannik Sinner in 2024 but you have to go all the way back to 2006 to find America's previous finalist when Andy Roddick came out second best against Roger Federer.
Roddick, however, does remain the last American man to win the US Open, his victory over Juan Carlos Ferrero coming in 2003. It ended a golden period for domestic players who had won eight of the previous 13 stagings of the tournament.
23-year-old Shelton has reached the semi-finals of the US Open before, but unfortunately that ended in defeat to 24-time major winner Novak Djokovic. His only other appearance in the last four of a major came in Australia last year where he was undone by Italian ace Sinner.
Victories over Tallon Griekspoor, Hubert Hurkacz, Denis Shapovalov, Stefanos Tsitsipas preceded his mammoth tussle with Alcaraz and, priced at 4/11, a semi-final clash with Tiafoe represents by far his best opportunity yet to reach a Grand Slam final.
Germany's Alexander Zverev remains favourite for the tournament at 21/20 as he bids to land a second Slam of the year after French Open success in June.
