Imagine Carlos Alcaraz and Emma Raducanu competing together for a Grand Slam trophy. How about Madison Keys and Frances Tiafoe as a duo? Iga Swiatek alongside Casper Ruud? Or Naomi Osaka with Nick Kyrgios?
Those are among the high-wattage pairs on Tuesday’s preliminary entry list for the reimagined U.S. Open mixed doubles tournament on Aug. 19-20, before singles competition begins Aug. 24.
