Tennis megastuds like Serena Williams and Roger Federer are household names. Steve Johnson and Nicole Gibbs, however, are not. Although they were the most dominant collegiate tennis players of their generation, that means nothing in the grand scheme of professional tennis. Yes, they both successfully made the pro jump, and yes, they're both ranked in the top one hundred. Barely. Try 37th and 89th, respectively.

Sure, it would be nice to win a grand slam. The last time an American man did it was Andy Roddick in the 2003 U.S. Open. Ladies, your odds are better. American women, led by the Williams sisters, are still as good as it gets—but chances are, you're not gonna be on Sports Center. Unless it's on a blooper reel. Just…be careful out there.
