Exactly one week today, a huge report dropped that detailed the system the Astros were using to steal signs during the 2017 World Series. The team reportedly had a center-field camera fixed on the catcher, someone decoded the signs on a monitor in the hallway between the dugout and clubhouse which was caught in their World Series championship DVD.

According to Joel Sherman of The New York Post. Sherman says that he heard Astros players may have worn a buzzer device on their body to help relay signs. From Sherman:

In recent days I have had scouts and executives talk to me about a variety of methods they think have been or could be employed, such as a realistic-looking electronic bandage placed on a player's body that buzzes in real time to signal what is coming — one buzz for a fastball, for example — if the surveillance determines what type of pitching is coming. One person I spoke to has ties to the Astros and said he already had spoken to MLB's investigators.

Since the report by Sherman came out, a photo has surfaced online that may point to what the article is speaking of.
