Serena Williams is five foot nine inches and has stated that she weighs two hundred pounds. After watching her match last night I think that her weight may have been underestimated and would have guessed her to be closer to weighing two hundred and forty pounds. Her serve was awesome, and she is the best female tennis player of all time, but the extra weight seemed to inhibit coverage of the full court. Serena has had several rolled ankle accidents but I can not help but feel that her weight contributed to last nights rolled ankle and subsequent forfeiture/loss. The optimal weight for someone who is five foot nine is between one hundred and thirty to one hundred and sixty pounds. Trying to make quick turns, pivots and stops with an extra fifty pounds has to be like an eighteen wheel, fully loaded truck trying to stop in a short distance. I am surprised that her coach let her play and has not required that she get back into shape.
