This post about catchers' ERA gets a little too stats-heavy for me to really follow, but it's a nostalgia trip for Bucs fans, featuring Don Slaught, Mike LaValliere, and my binky Zane Smith (as well as the rest of the Bucs' rotation in the early '90s). The basic idea is that the Bucs' catching platoon provides one of the rare situations where we have a large enough sample to isolate how different pitchers performed with different catchers. It doesn't look like it made much difference; the big difference comes in pitchers' BABIP with different catchers, and (as a magisterial comment from Dann M explains) that may well be due to the way that Leyland's other platoons affected the defense.
