Serena Williams is back at the U.S. Open, and this time she has her sister by her side. Four years after suggesting she was evolving away from tennis, the 44-year-old legend has reunited with Venus Williams for a doubles wild card entry, the United States Tennis Association confirmed Wednesday. The sisters will compete together for the 10th time at Flushing Meadows, a venue where they have already lifted the trophy twice—in 1999 and 2009. Their partnership has yielded 14 major titles, making them one of the most decorated doubles teams in history.

Serena's return to New York began earlier this week when she paired with 23-year-old sensation Carlos Alcaraz in mixed doubles. The duo, both recovering from injuries, delivered an electrifying opening-round victory before falling to Belinda Bencic and Flavio Cobolli in the quarterfinals. Alcaraz, the world No. 3 and seven-time Grand Slam champion, described the experience as a privilege. I felt the pressure, he said. It’s as if I was playing the final of a Grand Slam. I just loved it and enjoyed every single second.

For Serena, simply being on the court again felt surreal. I haven’t played a ton of tennis, but it still felt good to get back out there and find your groove, she told NBC News after the mixed doubles loss. I honestly never thought I would be back here playing tennis. So it’s kind of surreal.

Widely regarded as the greatest women’s player of all time, Serena owns 39 Grand Slam titles: 23 in singles, 14 in women’s doubles, and two in mixed doubles. She spent 319 weeks as the world No. 1 and is one of only two women, alongside Steffi Graf, to win all four Grand Slam singles titles and an Olympic gold medal. Though she never formally announced retirement, she stepped away from the tour in 2022, citing a desire to evolve away from tennis.

Her return to competition came in June at Wimbledon, where she injured her right knee during her first-round singles match. That setback followed a four-year break from the sport. Alcaraz, meanwhile, was sidelined for four months with a right wrist injury suffered at the Barcelona Open in April. Both have been navigating their comebacks with caution.

Serena acknowledged that her time away has changed how she views the game. My relationship with tennis is a love-hate thing, she said. I love it, and I hate to lose. But it’s definitely more fun now. I just try not to put as much pressure on myself.

The women’s doubles tournament begins Sept. 3. This year’s U.S. Open offers a record $108 million in total player compensation, with the men’s and women’s singles champions each taking home $5.5 million. The Williams sisters’ wild card entry adds an extra layer of nostalgia and excitement to an already star-studded event.
