Top 10 Performance-Enhanced Athletes of 2009

In late 2007, Pettitte admitted to using HGH (human growth hormones, though not a steroid, was still a banned substance in the Major Leagues). Taking the honest route, he admitted unlike his friend, Roger Clemens. Since then, Pettitte has been on a roll winning at least 14 games each season and adding another World Series championship to his resume.

A-Rod denied taking steroids, but in the end he came forth and told what was true all along. Taking steroids in 2003, he won the his 3rd consecutive AL home run with 47 homers (52 and 57 the 2 years prior to 2003) crown and his first MVP. Afterward, in 2004, he managed to only hit 36 homers, a distinguishable drop off. But I guess karma is on his side, he's supposedly is clean now and the result of that is a World Series ring.

One of two Vikings caught using a banned supplement in 2008. He appealed his suspension and have bounced back nicely totaling 6 sacks in 9 games so far.

One look at these him and a glance at his names and instantly one though comes to mind -brothers! he's related to Kevin Williams. Well not exactly. Although they aren't blood brothers, they seem to be locker room bros as both of them have been busted for taking water pills (a form of steroids). They have been the anchor for the Minnesota Viking's defense and it shows this year as the Vikings are ranked in the top 6 against the run.
