A Star-Studded Pairing

Serena Williams and Carlos Alcaraz will team up for the US Open mixed doubles after receiving a wild card into the main draw, the U.S. Tennis Association announced on Saturday. The pairing marks Williams' first competitive appearance at the US Open since 2022, bringing the 23-time Grand Slam singles champion back to Flushing Meadows in a high-profile partnership with the defending men's singles champion.

Williams, 44, returned to competitive tennis in June after nearly four years away from the sport. Since her comeback, she has played at Queen's Club, Wimbledon, and Cincinnati, where she partnered with her sister Venus in doubles. The Williams sisters lost in the opening round of the Cincinnati Open to Marta Kostyuk and Peyton Stearns, their first tournament together since the 2022 US Open.

Alcaraz, who has been sidelined since April with a right wrist injury, confirmed earlier this week that he would return to New York to defend his US Open singles title. The mixed doubles event, which begins Tuesday, will give him a competitive outing before his singles campaign starts. Alcaraz expressed his excitement on X, posting "Let's gooooo!" with a fire emoji, tagging Williams.

The partnership brings together two generations of tennis greatness. Williams has won six US Open singles titles and claimed the mixed doubles title in 1998 with Max Mirnyi. Alcaraz, a two-time US Open men's champion and world No. 2, is looking to regain his form after a four-month layoff.

Williams' US Open Plans

Williams is not planning to play singles at this year's US Open. The USTA had been holding one women's wild card, which was given to Sofia Kenin, the 2020 Australian Open champion. This decision effectively rules out a singles appearance for Williams, who last played singles at the US Open in 2022, losing to Ajla Tomljanović in the third round.

Williams' return to tennis this summer has not been without challenges. She sustained a knee injury during her first-round loss to Maya Joint at Wimbledon in June. Despite this, she continued with doubles play, including the Cincinnati Open with Venus. It remains unclear whether the Williams sisters will also partner in the US Open women's doubles draw.

For Alcaraz, the mixed doubles provides an opportunity to ease back into competition. He has not played since April, missing the French Open and Wimbledon due to his wrist injury. The Spaniard, who won his first Grand Slam title at the US Open in 2022, will be aiming to defend his singles crown when the main draw begins August 30.

Mixed Doubles Field and Format

The mixed doubles event has been revamped in recent years to attract top singles players. The winning team will share a $1 million prize, and the tournament is structured as a two-day, 16-team event. Matches use a best-of-three format with sets played to four games, no-ad scoring, and a 10-point match tiebreak if needed.

The field includes several high-profile pairings. Aryna Sabalenka and Novak Djokovic will team up, as will Iga Swiatek and Casper Ruud. Sara Errani and Andrea Vavassori, who won the title in 2025, are defending champions. Jessica Pegula and Taylor Fritz re-paired after their original partners, Jack Draper and Elena Rybakina, withdrew from the event. Diana Shnaider, left without a partner when Daniil Medvedev withdrew, was given the chance to find a new partner before the draw.

Other wild card entries went to Karolina Muchova and Jakub Mensik, Emma Navarro and Tommy Paul, and Andreeva and Rublev. The qualifying tournament takes place Monday, with the main draw running Tuesday and Wednesday at the USTA Billie Jean King National Tennis Center.

Context on the Men's Singles Field

Alcaraz's return comes at a time when the men's singles draw has been affected by withdrawals. World No. 1 Jannik Sinner pulled out due to a right knee injury, having not played since winning Wimbledon in July. Jack Draper and Holger Rune also withdrew, citing injuries. With those absences, Alcaraz enters as the highest-ranked player in the men's field, strengthening his prospects for a successful title defence.
