Originally signed as a shortstop, Castillo hit .239 in three seasons of Rookie ball before the Phillies decided to make him a pitcher in 2010. When the Phillies left him off their 40-man roster, the Cubs plucked Castillo in the Rule 5 draft, and they retained his rights by keeping him on their big league roster for most of 2012. He only pitched 36 innings, however, a significant setback because he needs more experience to improve. Castillo is all about arm strength. His fastball ranges from 93-97 mph in short stints, and sat at 90-93 when he started in previous years. He can run his hard slider up to 86 mph but it doesn't feature much break and finds the strike zone more than his fastball. If Chicago wants to develop him as a starter, he'll probably open 2013 in high Class A. If they keep him in the bullpen, he'll proceed to Double-A.
