In a reflective, moving essay for Vogue, Serena Williams—who is not only one of the greatest tennis players of all time, but one of the most important athletes in sports history—has announced that she's "evolving away from tennis." In the piece, Williams cites a desire to focus on her family, as well as her venture capital firm, Serena Ventures, as the main reasons why this summer's US Open will seemingly mark the final time she competes.

"Believe me, I never wanted to have to choose between tennis and a family," Williams wrote. "I don’t think it’s fair. If I were a guy, I wouldn’t be writing this because I’d be out there playing and winning while my wife was doing the physical labor of expanding our family. Maybe I’d be more of a Tom Brady if I had that opportunity."
