Ray at 2B, Gonzo at 3B, and I'd actually platoon Falk and Corporan in CF.
For very game I HAVE to win-- playoffs, for example-- Parker is the every day RF, and I'd platoon at 1B and LF; Gonzalez and Halman platoon in LF, and 2 guys you haven't posted, Ramirez and Vina, platoon at 1B. Snow is the DH and Tarraga is the catcher. You have a ton of flexibility to rest everybody with this crew; it's a really nice position player roster.
