After the Yankees complained to Major League Baseball about the Red Sox stealing signs, Boston has fired back with its own complaint against New York.
According to ESPN's Buster Olney, the Red Sox filed a complaint to the league about the Yankees pointing a YES Network camera at Red Sox bench coach Gary DiSarcina during last weekend's series at Yankee Stadiium. Olney reports that the Red Sox were aware of the camera from previous games and moved DiSarcina to a different spot that wouldn't pick up his signals.
This comes after the report that the Yankees caught the Red Sox stealing signs from their catchers using an Apple Watch. New York also filed a complaint against pitcher Doug Fister for potentially using an earpiece, but it was later discovered just to be a mouth gard hanging from his ear.
