Keep in mind that there are a lot more substances than steroids on the MLB list. There are guys getting popped for basic over the the counter GNC stuff.
I am not excusing Rafi, he should know the rules. however I wish the MLB would announce exactly what the postives were. There is a big difference between juice, and certain weight gainers. I just hope they say exactly what the substance was. Just because it's a banned substance doesn't make it juice.
That would certainly make more logical sense wrt Raffy's situation.
