Seiji Kobayashi

Plenty of people glance at a catcher's batting average and decide he is underwhelming. Wrong instrument. Seiji Kobayashi, born in Sakai, Osaka, came out of Doshisha University to the Yomiuri Giants and has spent his career at 178 cm crouched behind the plate. Reading a pitcher's condition, calling the sequence, throwing runners out, keeping an ugly game from collapsing: almost none of that reaches a box score. He has worn the mask for Japan's national team too, and staying composed in that chair is an achievement by itself. Younger catchers keep arriving and he keeps his place, which suggests he survives on trust rather than statistics. I respect people who do the unglamorous job for years.
