Sharapova shot up to 6’2” in her early teen years. Her arms hang almost to her knees. Neither of her parents are nearly that tall. Likely an HGH case. Unclear that she’s juicing now - doesn’t appear to have the muscle mass, acne, ‘roid rages, etc. that characterize Williams. Although she is/was hirsute; laser or electrolysis may have taken care of that. Plus Williams has clobbered her 18x in a row.
And that shrieking - she’s unwatchable.
