Dave Bresnahan was catching for the 1987 Williamsport Bills, who were in seventh place in an eight-team league, playing the last-place Reading Phillies in late-August game. With a runner on third base, Bresnahan switched catcher's mitts and put on a glove in which he had secreted a shaved-down potato. When the pitch came in, Bresnahan fired the white potato down the third-base line, enticing the runner to sprint home. Bresnahan then tagged the runner with the baseball, prompting the umpire to award the runner home plate for Bresnahan's deception, even though he clearly had been tagged out with the ball.
