US Open LIVE: Mixed doubles scores and updates featuring Serena Williams and Carlos Alcaraz

Serena Williams and Carlos Alcaraz make their return to tennis in an all-star pairing at the US Open mixed doubles tournament.

23-time grand slam champion Williams is competing in New York four years after the final competitive singles match of her career - or at least, the first phase of her career - before she began “evolving away” from the sport.

But the 44-year-old is back in action alongside Spaniard Alcaraz, who has not played in four months due to a troublesome wrist injury, but makes his return to grand slam action in order to defend his singles title at Flushing Meadows.

Elsewhere in the high-profile but controversial mixed doubles event, which is in its second year after a major revamp, world No 1 Aryna Sabalenka and 24-time grand slam champion Novak Djokovic are the top seeds, with the all-American pairing of Jessica Pegula and Taylor Fritz the second seeds.
