I would say it's almost guaranteed that they go back to a 12 man staff, 5 man bench once Morgan is healthy. Like others said, the only reason they have 13 pitchers now is because some pitchers were unavailable and Hart was coming back soon. Keeping a 4 man bench with Morgan back would leave Nieves, Counsell, Morgan/Gomez, and Kotsay on the bench. Nieves is the only backup catcher so he is basically useless as a PH (some would argue he's useless everywhere else as well). That leaves essentially 3 on the bench. There's really no reason to keep 13 pitchers, especially when Greinke comes back, because most of our starters can go deeper into games. It would be nice to have another backup IF on the bench but since there's really nobody worthy to call up, I would say Boggs ends up staying and Almonte goes down. I don't know whether that happens sooner (when Hart comes back) or later (when Morgan comes back) but I would almost guarantee that's how it plays out.
