Carlos Alcaraz reveals Emma Raducanu needed some time to think about his mixed doubles and adds now she is going to be “the boss” when they team up at the US Open.

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 organizers said on Tuesday, with former singles champions Carlos Alcaraz and Emma Raducanu teaming up.

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.
