The US Open's radical mixed doubles format, preceding the major tournament, has been criticised by doubles specialists who rely on mixed tennis earnings.
Alcaraz expressed excitement about playing with Raducanu, stating he has a good relationship with her and humorously noted she took some time to agree to the partnership.
Alcaraz secured a first-round victory at Queen’s Club against Adam Walton 6-4, 7-6(4), marking his 14th consecutive win, though the focus remained on his upcoming mixed doubles partnership.
Jack Draper, also competing at Queen's Club, is set to partner with Qinwen Zheng at the US Open and acknowledged Raducanu's choice of Alcaraz as the 'best partner'.
