Notes
	He is starting the year on the IL, but allegedly feels good throwing. This ranking bakes in the obvious risk of drafting a pitcher with an arm injury, but he could provide great dividends if he returns fully healthy after the opener. I, however, am more than happy to pass. Anthony Gambale - Roto Street Journal
