He's had PLENTY of problems, and hasn't pitched in a while. He looks like a lost cause right now in terms of a player. He should be focused on getting better.
It's interesting, because on the Marlins' message board, there was somebody posting right after he was drafted mentioning that he had a drug problem, and everybody pretty much dismissed him. You'd think if this guy knew, the Marlins brass should've known and passed on him.
Actually, the best rookie hitter in the AL is Joe Mauer. With the knee issues last year, he actually spent enough time on the DL (and not enough time on the active roster) to stay a rookie another year.
