He's a tweener like Valiaka, Sutton (and maybe even Frazier) who probably doesn't have the bat for the positions he could credibly play on a daily basis, but guys like that can be useful on the bench. Some can even be among the more valuable guys on the team even though they may not be able to claim any specific position (which is where I think Frazier would fit on a good team). I'd envision Rosales having a career similar to guys like Brendan Harris, Greg Dobbs and Geoff Blum and when I think about players coming up through the system over the last 10 years that would qualify as a sucess. Certainly not a throwaway while he's cheap and has options.
