Katsuhiko Kumon

Here's a guy whose career stat line looks modest on paper — 252 games, 8 wins, a middling ERA — and yet buried in there is one of the wildest records in Japanese professional baseball: 182 consecutive appearances without taking a loss from the moment he debuted. Let that sink in. Most relievers are lucky to string together a few months without a blemish, and this kid from a tiny village in Kochi went nearly seven years before the loss column finally got him in July 2020. He bounced through the Giants, the Fighters, and the Lions, quietly racking up holds and doing the unglamorous bullpen work that keeps games alive without ever getting the glory. The cross-step sidearm conversion midway through his career was a gutsy reinvention too. He retired after the 2023 season, but honestly ending up as a batting practice pitcher for the Hanshin Tigers in 2024 feels right — still on the field, still useful, still a baseball lifer. The record alone earns him a permanent footnote.
