Sorry, I thought you were talking about a future comp for Chris Marrero, not Morse.
Ok but as for the Marrero/Gaby Sanchez comparison that might not be too far off. Look what Marrero did last year in full season in AA:
2010 (AA): .294/.350/.450, 18 HRs 82 RBIs
Gaby Sanchez's numbers from the Majors last year: .273/.341/.448, 19 HRs 85 RBIs
Eerily similar, in a perfect world that is what Chris Marrero will become.
