The Boston Red Sox used their video replay room to steal signs from opposing pitchers and catchers during their 2018 World Series championship season, according to a report.
The report cited three anonymous people who were with the Red Sox that season.
Players would visit the replay room to decipher their opponents' sign sequence and then relay the information to the dugout. Someone from the dugout would then communicate with a baserunner, who would use body movements to relay pitch information to the batter.
"We were recently made aware of allegations suggesting the inappropriate use of our video replay room," the Red Sox said in a statement. "We take these allegations seriously and will fully cooperate with MLB as they investigate the matter."
