Another interesting storyline of the 2025 U.S. Open featuring a new format of mixed doubles competition that included several star tennis players participating including one of the all-time great women’s tennis players, Venus Williams. Serena Williams and Venus Williams are both among the greatest women’s tennis players of all time with Serena making a strong claim as the best of all time. During the U.S. Open, she defeated Coco Gauff, another young African/Black female tennis player that has previously been inspired by the Williams sisters. Although both Venus Williams and Serena Williams no longer are winning Grand Slam tennis tournaments as they did during the 2000s, their impact on tennis is still felt decades later. Those weeks in New York City showed the “Williams sisters’ effect” is still present.
