Andy Roddick

Here's why we really need to watch out for this American sensation this year: this could well be his last Wimbledon! After 13 years of professional tennis, a recently-recovered hamstring, and several other complications, he has publicly admitted that this is probably going to be his last meaningful performance at the All England Club. 

Over the years, Roddick has been carrying the burden of his legacy (the likes of Andre Agassi, Pete Sampras and Jimmy Connors to name a few) with elan and has even won the US Open, not to mention became World No. 1 shortly after his 21st birthday. If this is going to be his last hurrah, then it's very likely that he's going to make this a good one--and we just can't wait to watch it!
