Investigators for Major League Baseball have determined that the Red Sox, who are in first place in the American League East and very likely headed to the playoffs, executed a scheme to illicitly steal hand signals from opponents’ catchers in games against the second-place Yankees and other teams, according to several people briefed on the matter.

The baseball inquiry began about two weeks ago, after the Yankees’ general manager, Brian Cashman, filed a detailed complaint with the commissioner’s office that included video the Yankees shot of the Red Sox dugout during a three-game series between the two teams in Boston last month.

The Yankees, who had long been suspicious of the Red Sox’ stealing catchers’ signs in Fenway Park, contended the video showed a member of the Red Sox training staff looking at his Apple Watch in the dugout. The trainer then relayed a message to other players in the dugout, who, in turn, would signal teammates on the field about the type of pitch that was about to be thrown, according to the people familiar with the case.

Being a Yankees fan I am happy they uncovered this but it makes no difference the accused the Patriots of cheating years ago.
