Murray celebrated his 22nd birthday Friday with a high-profile match against Juan Martin del Potro in the Madrid quarterfinals. He's already won three titles in 2009 -- in Doha, Rotterdam and Miami -- while becoming the first British player to make No. 3 in the ATP rankings. The Scot could even shoot past Roger Federer to No. 2 in next week's rankings if he wins the Madrid title and Federer loses before the final.
