On June 12 1884, 1884 – Dissatisfied with umpire Jack Brennan’s calls, hundreds of fans storm the field at Oriole Park in an American Association game between the Orioles and Louisville Eclipse. One man wielding a large revolver threatens to shoot Brennan if he makes any more bad calls. Police have to be called in to clear the mob, and after the game, which ends in a 4 – 4 tie, Brennan is slugged to the ground by a fan and has to be taken to the Orioles clubhouse, then to OF Jim Clinton’s home for his own protection, before being whisked out of town on the first train.
