Fans think they know why Emma Raducanu did not embrace Jack Draper after the pair played in the first round of the new US Open mixed doubles event.

Emma Raducanu and Carlos Alcaraz’s all-star partnership was brought to a premature end as they were beaten in the first round of the revamped US Open mixed doubles.

The main singles draw at the US Open does not start until this weekend but the mixed doubles are already well underway. The first round of matches took place last night with Emma Raducanu and Carlos Alcaraz teaming up on the court. They were dumped out in the very first round by Jack Draper and Jessica Pegula, who progressed to the semi-finals.
