How about a breakdown of the quality of lineups that Butera's pitchers have faced? He seems to get the 'day game after night game' starts fairly often, along with the other scrubs of both the Twins and their opponents. Maybe it's just me. As for being useful as Liriano's personal catcher, well, the idea that Liriano needs a replacement-level catcher to be effective sounds like another reason to trade Liriano, not elevate Butera to near-everyday status. That leaves the 10 starts with non-Liriano pitchers. Given that CERA is already suspect at best for career-sized samples, those 10 starts represent no discernible analytical value to me. I agree with you the Twins are out of it. I even agree with you that Butera should catch more, though not for the reason you suggest, and not nearly to the same extent. I'd just like to see Butera out there a little more just to save wear and tear on Mauer and even Doumit. That being said, the idea that there's no risk to elevating Butera to near-regular status isn't really true. The Twins still need to put butts in the seats, and it's not going well. Selling already disenchanted fans on Butera catching more than Mauer based on what's likely no more than a statistical anomaly would be an ugly PR undertaking. But let's say you throw attendance caution to the winds, keep running Butera out there the rest of the season, and get similar non-Liriano numbers. Now you're going to dump Morneau, convert an already-expensive Mauer to a much less valuable position , and insert a replacement-level bat into the starting lineup based on what's still a microscopic sample size of one of the weakest predictive stats in baseball? Pass.
