A new report accuses the Boston Red Sox of using their replay room to steal signs during their World Championship season in 2018. According to The Athletic, Red Sox players would go into the replay room and determine their opponents' sign sequences. Once they figured that out, they would relay the information to the dugout. The information would then be given to baserunners, who would use body signals to let the batter know what pitch was coming next.
"It's cheating," a source who was with the Red Sox in 2018 told The Athletic. "Because if you're using a camera to zoom in on the crotch of the catcher, to break down the sign system, and then take that information and give it out to the runner, then he doesn't have to steal it."
The Red Sox were unable to use the replay room during the postseason because Major League Baseball had a staffer present in the room during games.
MLB told the Athletic that they would investigate the allegations against the Red Sox.
"The Commissioner made clear in a September 15, 2017 memorandum to clubs how seriously he would take any future violation of the regulations regarding use of electronic equipment or the inappropriate use of the video replay room," the league said in its statement. "Given these allegations, MLB will commence an investigation into this matter."
The Houston Astros have also been accused of using electronic equipment to steal signs in 2017.The Athletic detailed their system, which including banging trash cans if a pitcher was planning to throw an off-speed pitch. Red Sox manager Alex Cora was a bench coach for the Astros that season and went on to manage the Red Sox in 2018.
