Roger Federer

This Swiss superstar may have turned 30, but he shows no signs of slowing down this year. He's already cinched three titles so far in 2012 and seems determined to turn the tide in his favor. Plus, all he needs is this one win at Wimbledon to take his tally from a six to a glorious seven, to finally equalling Pete Sampras' record! As such, the stakes for him are incredibly high this year.

With 67 career titles and a whopping $63,343,910 in prize money to accompany it, we're rooting for Federer this year as well
