NEW YORK (AP) — Top-ranked Aryna Sabalenka and 24-time Grand Slam champion Novak Djokovic headline the initial list of 16 teams entered into the U.S. Open mixed doubles championship.

The tournament was overhauled last year, with a $1 million prize going to the winners, in an effort to get top singles players to compete. Many of those types of stars were listed among the teams announced Monday by the U.S. Tennis Association.

Iga Swiatek and Casper Ruud, the runners-up in 2025, are entered again, along with Elena Rybakina and Taylor Fritz, the Japanese duo of Naomi Osaka and Kei Nishikori, and Jessica Pegula and Jack Draper.
