Serena Williams and Carlos Alcaraz are teaming up at the U.S. Open.

The tennis stars will play together in the mixed doubles at Flushing Meadows next week, the U.S. Tennis Association announced on Saturday.

Williams, who is not expected to play singles, returned to competitive tennis earlier this summer after nearly four years away from the sport.

The 44-year-old has since played doubles at Queen’s Club, Wimbledon and Cincinnati as she continues her comeback.

Alcaraz is making his return to the court for the first time since April after being sidelined with a right wrist injury.

The Spaniard is looking to defend his US Open title from a year ago.
