Not enough room in the Round Rock OF for Pence, Anderson, Rodriguez, and Jimerson. However, Rodriguez won't be able to play the field until about May-June, so that may open up a spot, at least temporarily, for Jimerson (assuming he clears waivers).
On that note, the Round Rock offensive lineup ought to be fairly salty this season. I don't know about the projected order (other than Anderson leading off), but Anderson, Rodriguez, Pence, Ransom, Klassen, Self, Conrad, and Munson is a pretty tough array of AAA hitters.
