they also have Cory Burns, Delabar, Drabek?, Hynes, Schultz, Francisco, Tolleson, Hague that all can be dropped without any issue. They obviously need to replace the major league spots that will come off the 40 man too (Cabrera, Rasmus...whoever's options they don't pick up).
I really think Burns is a candidate to get plucked. He's supposed to be a plus defender who can play 5 positions and makes average contact, runs well and might be able to hit lefties (.915 OPS in 500 PAs). Seems to me he'd fit in very well as a 25th man. He seems like he'd have more value to this team than Tolleson or even Valencia.
