I don't know if Yost has much choice at this point. With a Saturday night/Sunday afternoon schedule, the backup is going to catch one of those. Likewise, with Miller coming down with a sore back and sore shoulder during the first two months, Moeller was their only option behind the plate. I know some people think that even on those days in which Moeller starts he should be pinch hit for in critical situations. That makes good sense. Of course, that sort of defeats the purpose of giving Miller a day off to rest his sore 35 year old parts. Besides, as someone noted, it's not like their record has been dramatically different with Moeller catching than with Miller.
