@Region Philbis,
And she really didn't play well. I'm sure she is not willing to continue to play if she can't play at a high level. I'm also sure that is not how she wanted to go out. I doubt she wants people pitying her and wants to orchestrate her swan song on her own terms. Ways Serena in particular and Venus and Serena in general have changed the game:
- Women players now work hard on their serves and the best players use it as a weapon to win points easily. That comes directly from Serena who probably has the best service motion in the history of the game.
- If Martina Navratilova proved the importance of physical fitness in women's tennis, Serena proved the importance of strength training. I doubt you'll find a top player today who does not hit the weight room as a regular part of their training regime. She wasn't the first to do it, just the first to demonstrate how effective it is in winning games.
- Serena really drove standing in at the baseline and taking the ball aggressively. Again, she wasn't the first to do it, but she was so successful that it has become the standard.
- The Williams sisters completely broke the color barrier in tennis. If you look at the top US women players, around half are people of color.
- Serena in particular completely exposed the subtle racism and misogyny in sports reporting. Refusing to accept or back down in the face of it has forced continuous evaluations at the top sports sites like SI and ESPN about how their reporters question women and POC about sports.
- Both sisters but Venus in particular have driven pay equality in tennis. At least at the major events the women now make what the men do.
