Why Serena Williams Is Glad To Get A Clunker Out Of Her System

— -- PARIS -- Part of what makes Serena Williams so compelling is that even though she is the world's best player, you can never be too certain of what you're going to get.

Despite being 33 years old, she has been ranked No. 1 for 118 consecutive weeks (and 242 total), dating to February 2013. During that stretch, she won the 2013 French Open but was also knocked out of the 2014 French Open in the second round. She's a five-time Wimbledon champ but hasn't made it past the fourth round there the past two years, and last year she had an epic meltdown in doubles due to a mysterious "virus'' that kept her from even successfully bouncing a ball on the ground.
