Yesterday the Royals spent a little bit of money (300K) to sign Dominican righty Darwin Castillo. Now reports state that Castillo is eighteen years old and throws between 88-92 mph. Castillo is also 6-5, 215 lbs and seems to have an easy repeatable delivery, that can be seen via youtube if you search his name.
Given his age, frame and delivery it isn't out of the question to expect that Castillo could add a few miles per hour to his delivery in the future. I love this kind of move for the Royals and it is the second time this offseason that they have signed a righty out of the Dominican Prospect League.
My hope is that with the Gil Meche contract coming off the books for the 2011 season, the Royals will be extremely active in Latin America this year and that this is only the beginning.
