Serena Williams is still better than you at tennis
Serena Williams is pregnant, very good at tennis, and can still beat you. The GOAT might be missing from Wimbledon in a couple of weeks, but she's still out on the court hitting a few balls. She posted a video of a light tennis workout. By light, I mean it's light for her. I would still be dying.
How cool is Serena? She won the Australian Open (pregnant) and is still putting in the work. I'm not sure GOAT quite covers it.
