I like the "multiple role player" approach. The core of this team is Bradley-Betts-Benintendi-Bogaerts for non-pitchers. I get the appeal of Martinez, but he is a threat to that.
Another name worth mentioning as a role player might be Brandon Phillips. Grab him, Morrison, Cashner and a reliever like Tony Watson, Matt Belisle or, if you feel like a reclamation project, Trevor Rosenthal...
