Raducanu and Alcaraz were given a wildcard for a shot at the winning prize of $1m (£740,000).

Emma Raducanu and Carlos Alcaraz might have lost in the revamped US Open mixed doubles - but they certainly won the hearts of the New York crowd.

In a party-like atmosphere at Arthur Ashe Stadium, Britain's Raducanu and Spain's Alcaraz saw their chances of claiming a $1m winning prize ended by fellow Briton Jack Draper and Jessica Pegula, who have reached Wednesday's semi-finals.

Despite the presence of home player Pegula, it was the losing pair who were heavily backed by a sizeable crowd at Flushing Meadows.

Pegula and Draper won 4-2 4-2 in the new shortened format, which is part of the US Open's "reimagination" of the mixed doubles.
