The Times reported that the video provided to the commissioner’s office shows Red Sox assistant athletic trainer Jon Jochim looking at his Apple Watch, then passing along a signal to outfielder Brock Holt and second baseman Dustin Pedroia, who was on the disabled list at the time.
The video then purportedly shows Pedroia passing the information to teammate Chris Young on second base, who then relays it to the batter.
