Yes, that's WHEN Butera came up, but it doesn't solve the riddle of why (or more importantly why he stayed from then on). Morneau returned, and Butera stayed. Not to mention, there isn't even a direct link since they don't play the same position (the obvious indirect link is the primary catcher also plays 1B). At any rate, this question got stuck in my craw, so I decided to look at box scores to see if I could shed some light on what underlying difference in the lineup made it OK to start the season with no Butera, but made him stay once he got there. Bear with me... The first fairly interesting observation I made, was that Doumit never DH'd in the first 20 games of the season. And Mauer only did four times. Morneau was DH'ing essentially every day. Parmelee made the team out of Spring Training as the starting 1B. He started there 18 of the first 28 games. The general situation was Parmelee at 1B, Morneau DH'ing, Mauer catching. Doumit got an occasional start in RF, and otherwise would Catch while Mauer played 1B. After Game 22, Morneau went out for a couple of weeks. It seems like Mauer may have been banged up, but not fully injured as he caught Game 21, had 22 off, and then DH'd four games in a row. Butera debuted in Game 25. From Game 29 to 36, Parmelee only got three starts at 1B, and with Morneau out that meant Mauer was playing half 1B and half C, while BUTERA caught the other half the time and Doumit DH'd. In Game 37, Doumit caught and tweaked his calf, remember? So he only DH'd from then until Game 49. Game 37 was also Morneau's return, but now he had been made the 1B instead of the DH (they were heading to interleague play AND Parmelee was sent down because he started out pretty awful). What's this all mean? Well, as near as I can tell, the difference between pre-Butera, and when Morneau got back is that Morneau moved back to 1B making Doumit the frequent DH. When Doumit wasn't DH'ing after this point, it was often Mauer. It seems like MAYBE "they" felt OK with just two catchers when they had someone else DH'ing most of the time, but when the DH role was filled primarily by one of the two catchers, "they" felt there should be a third on the roster. To me, all this means it's likely there will be a third catcher if Doumit is the presumed first option at DH.
