Serena Williams is Athlete of the Year (and Decade)

The year-end and decade-end assessments are pouring in and Serena Williams (and Roger Federer) are racking them up.

Some might argue that Williams, 28, is the best story in sports (notwithstanding her temper tantrum at the 2009 U.S. Open). Consider her accomplishments this decade: She won nine of her 10 Grand Slam singles titles and two Olympic gold medals in doubles (with her sister Venus), and she recently reclaimed the No. 1 ranking. She boasts the most powerful game in modern tennis, and she is best when the stakes are highest. Throw in the nearly $29 million in prize money -- most of it earned in the aughts -- and it's an improbable haul for a woman who was schooled in the game along with Venus by their father, the self-taught Richard, on pockmarked public courts in Compton, Calif.

Serena's sister Venus ended the decade at #6.
