The Red Sox used an Apple Watch to steal signs from the Yankees and other teams during games this season, reports the New York Times.
Yankees general manager Brian Cashman sent a complaint -- complete with video footage as evidence -- to the commissioner's office in August. The footage is said to show Red Sox trainers using an Apple watch to send messages to players in an effort to alert them of the incoming pitch from the opposing pitcher.
MLB investigators found that the Red Sox stole signs from catchers on multiple teams, including the Yankees, but the other teams were not disclosed. The Red Sox admitted to the commissioner's office that their video replay personnel sent signals to trainers, who then sent that information to players.
"It's always been a game within a game, but the use of electronics takes it too far," Yankees OF Brett Gardner said, according to Bryan Hoch of MLB.com.
In response, the Red Sox filed a complaint against the Yankees and accused them of using YES Network cameras to steal signs. When asked about the counter-complaint, Yankees manager Joe Giardi said "No chance. We're not doing it," according to David Lennon of Newsday.
