Bautista, Encarnacion, Reyes, Cabrera, Sierra, Rogers, Perez, he may have a relationship with a few of them. Realistically though, he`ll probably take the best offer and it`s unlikely to be a factor.
Edit: Even though it`s unlikely to be a factor in FA, I still think there`s some value in the so-called ``Dominican connection`. For example, if the price on Starlin Castro were low enough he`d be an excellent target. If the problem is in his approach as people are suggesting, EE and Bautista would be ideal teachers.
