The revamped US Open mixed doubles tournament, featuring blockbuster singles players in action, threw up some unexpected results on Tuesday, as the likes of Novak Djokovic and Carlos Alcaraz suffered opening round exits as they struggled to share the limelight on court with their partners — Olga Danilovic and Emma Raducanu, respectively.

The Serbian duo of Djokovic and Danilovic were sent packing 2-4, 3-5 by the Russian pairing of Daniil Medvedev and Mirra Andreeva.

Meanwhile, Spain’s Alcaraz and Britain’s Raducanu were ousted after a 2-4, 2-4 loss to the Anglo-American duo of Jack Draper and Jessica Pegula.
