I have sandoval in and was waiting for wieters to come up. However someone had dropped posada when he went on the DL and i notice he is about ready to come back in a week or so. Do I make the move and drop wieters or do I stick with my original plan?

Stand pat. By the time Posada's gotten up to game speed, Wieters will probably be about ready to come up, or already be up. Wieters is a better hitter than Posada and on the rise, so only pick up Posada if you want trade bait. Sandoval's fine while Wieters is in AAA.
