Emma Raducanu will team up with French Open champion Carlos Alcaraz in the mixed doubles at the US Open, with a prize of $1 million (£741,000) on offer for the winners. The new doubles team – who can expect to be given a portmanteau nickname of either “Alcaranu” or “Raducaraz” – are one of several eye-catching partnerships set to make their debuts in New York in August.

Nine of the world's top-10 men and nine of the top-10 women have officially entered into the U.S. Open's revamped mixed doubles event, tournament organisers said on Tuesday, with former singles champions Carlos Alcaraz and Emma Raducanu teaming up.
