Hateful lowlight: Doping during his MVP campaign and lying about it for a year afterward
Steroids in baseball feels so 2007, but the game's premier performers still juice up. After capping off his 2011 MVP season, he failed a urine test for having "insanely high" levels of testosterone in his system. Braun won his appeal of the drug test after a second party lab found normal testosterone levels, but the New York Times believe he won his appeal "won on a technicality." This past February, he was connected to a clinic that had sold PEDs to athletes, reportedly owing the place $20,000-$30,000. Bruan cut a deal with MLB officials and is currently serving a 65-game suspension. Nobody likes a cheat. He's still got that money tho!
