If your brother wrote a tell-all book about your deepest, darkest secret, you would probably kick his ass, right?   Yes.

Mark McGwire’s estranged brother, Jay McTattleTale, wrote a book chronicaling their rampant uses of performance-enhancing drugs through the 1990s.  That is right up there with sleeping with your brother’s wife on the list of things you should never do to a sibling.

McGwire said he’s pretty “sad” over the whole ordeal, and that there is likely no chance he’ll ever forgive his little brother.  In fact, he used the word “sad” exactly seven times to describe the book during his 8-minute media on Thursday.

“You try to be a good person, you try to take care of somebody, be a good brother,”McGwire said… sadly. “It’s sort of sad. It’s a sad day for my family. I don’t know how a family member could do something like that.”

Big Mac also reiterated that the only reason he ever used steroids was to heal from injury.  Jay, a former body builder, more or less said that in The McGwire Family Secret: The Truth about Steroids, a Slugger and Ultimate Redemption as well, but added that Mark knew very well that he was also gaining strength and size.

“I don’t plan on ever seeing him again,” continued McGwire, the St. Louis Cardinals’ new hitting coach.

I don’t blame him. What a horrible thing to do… this is the perfect example of why money is the root of all evil.
