Serena and Venus Williams will play doubles at U.S. Open, go for 15th Grand Slam together

Serena and Venus Williams have accepted a wild card to play doubles at the U.S. Open.

The sisters have 14 doubles Grand Slam championships, tied for second in the Open era, including two at the U.S. Open in 1999 and 2009. They have not lost a title once they have reached the finals. Their most recent doubles Grand Slam title was at Wimbledon in 2016. They also have three Olympic gold medals in doubles.

Serena, who turns 41 next month, told Vogue in this month's issue that she will move away from competitive tennis after the U.S. Open. Venus, 42, has not indicated when she will retire. She holds 49 singles titles and seven Grand Slam championships.

The last time the sisters played in a major tournament as a pair was the 2018 French Open, losing in three sets in the third round. Since then, Serena entered two doubles events with other partners: one with Caroline Wozniacki in January 2020, and one with Ons Jabeur this June.

Serena will also be vying for her 24th Grand Slam singles title. She opens play against Danka Kovinic on Monday. Venus will take on Alison VanUytvanck in her first-round match on Tuesday.
