Santiago coming back

Benito Santiago is about a week from playing baseball again, but he said that he'll need two weeks to get game ready. Surely Pena won't put him in the line up for the final week of the season at Buck's expense? I know that the Royals are paying Santiago a couple million dollars this season and next, but John Buck is a better catcher. I'd hate to see Buck on the bench this season or next just so we can justify the mistake we made when we signed Santiago.
