It was Oct. 22, 1933, at the Jingu Baseball Stadium. The winner of the day's So-Kei (Waseda vs. Keio) match would lift the trophy for the year.

The teams were neck-and-neck, when Keio sent Shigeru Mizuhara to field third base. Waseda went wild with fury, as earlier in the match Mizuhara had repeatedly -- and often successfully -- challenged the umpire's calls.

As the fielder took his position, the Waseda crowd began throwing garbage at him. Mizuhara tossed the trash aside -- all save a half-eaten apple, which he threw right back at the Waseda supporters. This angered the fans, and when Keio's two-run home run swept his team to victory shortly after, they poured onto the field in fury.
