The practice of catchers using their fingers to flash a combination of signs for pitchers to decipher, a strategy that is almost as old as the sport itself, could be on the verge of becoming obsolete.

Major League Baseball will begin testing new technology that allows catchers to electronically communicate signs to pitchers at one of the lower minor league levels within the next couple of weeks, a system designed to both quicken the pace of play and suppress illegal sign-stealing methods.

A memo introducing the new system, a copy of which was obtained by ESPN, was sent to officials of the eight teams that make up the Class A California League on Friday. In it, MLB announced plans to begin testing on Aug. 3 a pitcher-catcher communication device developed by a company called PitchCom.
