While Jack Draper and Jessica Pegula may have said all of four words to each other before teaming up for this week’s U.S. Open mixed doubles tournament, the two already sound like an “old married couple.

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.

The Vuori performance and lifestyle brand has embarked on a multi-year partnership with Jack Draper. The brand said the move expands its athlete roster and marks an accelerated push into tennis. The British player will serve as a global brand ambassador and will wear Vuori clothing at this year’s US Open Tennis Championships.

The athleisure brand found the face of its move into big-time sports in Mr. Draper, a Top 5 player and fashion darling.

Jack Draper has signed a major multi-year deal with a new clothing sponsor, Vuori. The British No. 1 will join forces with Jessica Pegula in the revamped US Open mixed doubles tournament on Tuesday, where they take on Emma Raducanu and Carlos Alcaraz, and he’ll be in a brand new kit.
