Sign Stealing and Discovery
On September 17, 1900, at home in game 1 of a doubleheader against the Cincinnati Reds, members of the Phillies were discovered to have been stealing opponents' signs using hidden wires and an electronic device.

Phillies’ backup catcher Morgan Murphy sat in center field by the team’s centfielder lockers and offices at the Phillies' ball park. The Phillies ran wires under the field from the seat to a battery-powered device buried in the dirt beneath the third-base coach’s box. Murphy spotted the opposing catcher’s signals to the pitcher and signaled once for a fastball and twice for a breaking ball. Phillies infielder Pearce Chiles coached third-base, received the signal beneath his feet, and then signaled to the batter.

During the third inning, Cincinnati’s Tommy Corcoran walked to the third-base coach’s box and began digging at the dirt with his cleats. Before the Phillies' groundskeeper could stop him, Corcoran had unearthed the electronic box and showed it to umpire Tim Hurst. Hurst disciplined no one, signaled the game to continue, and is reported to have shouted, “Back to the mines, men!”.
