Girardi said the Yankees reported the team’s cheating to Major League Baseball, but he declined Thursday to reveal which team it was before he simply said, “Put two and two together.” The Yankees filed a complaint in 2017 against the Red Sox, a team that MLB learned was using Apple Watches to decipher the signs given by a Yankees catcher. That same investigation also said that the Yankees had improperly used the dugout phone, which led to a fine.
