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.
I'll give Melvin credit for this: With a team that was out of it before Memorial Day, they showed incredible signs of life in the last month and played Boston, Anaheim, Texas and Oakland tough in September, playing the role of an active spoiler.
