This day in baseball: Digging up a ploy

On September 17, 1900, Reds shortstop Tommy Corcoran left his position and began digging around the third base coaching box with his spikes at Philadelphia Park. The Reds captain ended up digging out a metal box containing an electrical device inside with attached wires. It was suspected that the device was being used by the Phillies in a sophisticated scheme to steal signs, though I’m curious as to what tipped off Corcoran to start digging.
