This player hasn't even been cleared to do more then preparatory tossing - not even within two months of throwing a bullpen. (I had heard of players released after completing their first bullpens. Which would mean they were medically cleared to throw bullpens.)
Moreover, the draft contract calls for Arizona workers comp law to be imposed - even though the player had only played in AZ for Spring trainings (played in other states for the seasons). And, the player and club are California residents and his last season (where he was injured) was solely in California. As you would suspect, the WC laws in AZ are much more favorable to employers when compared to Cal WC.
