The key is when a player has been added to the 40 man roster. IIRC, Zambrano started out his pro career as a position and was later converted to a pitcher. So, he may have spent more than three or four years in the minors, exposed to the RuleV draft, and nobody selected him before he made a 40 man roster. I didn't look at Zambrano's records, but this is a technically possible explanation.And, about Neyer's piece. The rule was changed several years ago. I remember when teams could only option a player a total of three times - period. Not the possible yo-yo situation of today's game where a player could be sent down, then brought back up, several times a year (like Victor Diaz this year).Later
