Baseball pitcher Nomino plays well at practice in the bullpen but plays badly in the real games. Moguro gives Nomino a cap to wear but he must also abstain from drinking alcohol until he is pitching in the major league. Nomino improves his pitching, but he cannot sleep on the night before a big game, and resorts to drinking sake. The next morning he is hung over and rushes to the game without his lucky cap and ruins his chance to play in the major league.
