It is worth noting that the Cubs do not have any available space on their 40-man roster so, unless they planned on dropping someone, the Cubs would have been unable to draft anyone anyways. The Phillies have one roster spot available, making them eligible to draft a player in this year’s Rule 5 draft. The Phillies will now pick fourth in lieu of the Cubs and seventh on their own if they clear a second roster spot. It is very unlikely that the Phillies will execute their second pick.
In 13 games in 2012 for the Cubs, Castillo posted a 7.88 ERA with a 2.250 WHIP. Castillo posted a 5.87 ERA across Single-A Kane County and High-A Daytona.
