Well in that case most big market teams will be going balls to the walls for this kid. Even all the other teams have a crack at him.
I guess I have not read as much about him as I should.
Overall, I'm not a proponent of chasing every new beaner-de jour. The fact that he is from Cuba has me suspecting two things about him.
One, I bet no team has seen anywhere near enough of him playing the game to make an accurate assessment. The Sox, as an example, had not seen Castillo play much over the 2 years prior to his signing.
Two, he is probably very raw in skill development. He comes from a desperately poor country where facilities are few. At 19 he probably has not played much high level ball.
I bet he is over rated.
