Should Butera start at Catcher?
Before you laugh, consider the following--
Joe Mauer has started 42 games at catcher. The starting pitchers in those games have pitched an average of less than 5.1 innings, while compiling a 6.53 ERA, a 1.63 WHIP, and given up a homer every 4.2 innings. Meanwhile, they have compiled 5.4 K/9, a 2.0 K/BB ratio, and the team is 17-25 in those games, despite averaging 5 runs a game, a figure that would put us 3rd in all of baseball for runs scored.
Ryan Doumit has started 33 games at catcher. The starting pitchers in those games have pitched an average of slightly more than 5 innings, while compiling a 6.12 ERA, a 1.59 WHIP, and given up a homer every 5.1 innings. Meanwhile, they have compiled 4.5 K/9, a 1.5 K/BB ratio, and the team is 12-21 in those games, despite averaging 5.5 runs a game, a figure that would put us 1st in all of baseball for runs scored.
Drew Butera has started 20 games at catcher. The starting pitchers in those games have pitched an average of slightly more than 6 innings, while compiling a 3.34 ERA, a 1.15 WHIP, and given up a homer every 12.1 innings. Meanwhile, they have compiled 8.2 K/9, a 3.0 K/BB ratio, and the team is 11-9 in those games, despite averaging only 4 runs a game, a figure that would put us 24th in all of baseball for runs scored.
Before you say this is simply an effect of Butera catching Liriano, consider some of the other pitchers on the staff. Scott Diamond, in 2 starts with Butera, has pitched an average of 7 innings, with a 0.00 ERA, a 0.71 WHIP, 6.4 K/9, 10 K/BB, and not given up a homer. With Mauer, it's 8 games, less than 6.1 IP, 4.35 ERA, 1.49 WHIP, 5.3 K/9, 3.2 K/BB and a homer every 6.1 innings. With Doumit, it's better than 6.2 IP, 2.63 ERA, 1.13 WHIP, 3.6 K/9, 2.2 K/BB, homer ever 27.3 IP.
With Pavano, Butera's 5 starts have yielded an average of 5.1 IP, 6.15 ERA, 1.52 WHIP, and 4.8 K/9. While all of these numbers are slightly worse than Pavano with Mauer (6.2 IP, 5.93 ERA, 1.02 WHIP, and 2.6 K/9 in 2 games), and Doumit (5.2 IP, 5.87 ERA, 1.48 WHIP, and 5.9 K/9 in 4 games), the following two numbers are WAY in Butera's favor; 14 K/BB and a homer every 26.1 IP. Those numbers dwarf both Mauer (2 K/BB, homer every 6.2 IP) and Doumit (3 K/BB, homer every 3.2 IP).
What Butera has done exceptionally well is limit hits and homeruns, which is directly leading to his success as a catcher. Does Liriano's hot run skew these results? Yes. But I think the evidence is compelling enough that its worth running Butera out there 3-4 times a week, and see if this continues. After all, I'm fine giving up 1 to 1.5 runs of offense a game, if it means saving 2-3 runs a game.
