Serena Williams has long been regarded as the best tennis player on the woman's tour. Especially when she only showed up to the majors, and won.
It's been almost a year since Serena has played a professional tennis match. During that time she's had significant health issues (foot surgery and pulmonary embolism), and now soon to be 30 years old. That's ancient in the world of women's tennis.
Will Serena ever compete again, and if she does, could she be as dominant as she once was?
