Another Year in Catchers Playing Other Positions
It’s not uncommon for ballplayers and managers and other people associated with baseball to evoke the “unwritten rules” of the game. For some, these unwritten rules seem absurd, a sort of arcane code that frequently contradicts reason. In essence, though, these “unwritten rules” amount to what a social scientist might refer to as “norms.” And, discussed in these terms, they make a little more sense. Using the term “norms” instead of “unwritten rules” removes some of the connotations of the latter term, and let’s us think about the game without choosing sides.
One norm that’s rarely scrutinized is the existence of distinct positions. The pitcher and catcher are highly regulated by the official rules, of course; otherwise, though, the league doesn’t have a lot to say about what the positions should be and how the men filling them should operate. For that reason, some positions are fluid. Corner outfielders are largely interchangeable. Middle infielders have generally the same jobs. Most of what makes the positions different are the existing norms about how they should be played and what you need to do to succeed there.
But as I noted a moment ago, there are exceptions. Catchers have a very different job from everyone else and that job is typically understood to be more important and more demanding than the other positions. It’s harder to be a catcher than it is to be an outfielder, but the positions also require dramatically different sets of skills to the point at which you can’t really compare the two in a meaningful way.
That doesn’t mean we can’t try. On occasion, catchers are asked to play positions other than catcher despite the required skills being quite different. How do those catchers do when they move from behind the plate? Does it tell us anything meaningful? Last winter, I performed an exercise to determine the performance of catchers at other positions. This represents an update of that piece, for the 2016 season.
