Longtime sabermetric favorite Gregg Zaun, the sometime “Practically Perfect Backup Catcher” (who would have made a pretty good starter for many teams), announced (or will announce, depending on the timing relative to this post) his retirement today. Zaun had played 16 seasons in the major leagues, and had actually put up above-average offense (very good for a catcher) the last two seasons (103 and 105 wRC+, respectively), but after coming back from injury to sign a minor-league deal with the Padres, decided that he just didn’t have the desire to play anymore.
Apparently he didn’t get the memo from Jason Kendall that aging catchers are supposed to linger on years after they were useful in order to keep teams from being tempted to play younger players. Maybe Zaun decided he didn’t fit the Kendall mode, given that he actually might still be able to contribute to a team: ZiPS projected Zaun to hit .255/.341/.403 in 2011. Perhaps Zaun finally realized that one must put up barriers to keep oneself intact.
Indeed, using this methodology for relating player performance to league average, Zaun turns out to be almost exactly average for his career. Instead of reciting easily looked-up stats (summary: Zaun was a slightly below-average defensive catcher who made up for it with good on-base skills), perhaps a more interesting tribute to Zaun (other than the awesome flash intro to his website) would be to rank his five most valuable offensive plays by Win Probability Added (WPA).
