Mysterious "Max" revealed - and he says Canseco's a liar

According to Sports Illustrated, trainer Joseph Dion has come forward and claims to be "Max," the mysterious trainer/steroids dealer that Canseco (in his upcoming book) claims to have introduced A-Rod to.

One problem. Dion says Canseco's full of shit and a liar.

From an ESPN.com report: "That's really, really funny because I am the one person that hates steroids," Dion was quoted as saying. "I'm against it 100 percent. And, A-Rod, at the time that I trained him -- and this I swear to God -- was 100 percent against steroids. He was one of the hardest working guys, and most natural guy, that I've met in my life. He hated steroids. We talked about it."

Yeah, I know. Canseco's a liar? What a shocker.

And, clean or not, A-Rod still can't drive in a run in a clutch situation.
