The Houston Astros continue to be at the center of controversy for electronically stealing signs at Minute Maid Park over the course of the 2017 season.
The scandal first came to light when former Astros pitcher Mike Fiers described the process in an interview, revealing that a center-field camera captured the signs of opposing catchers in real time.
The feed was then transmitted to a television in a tunnel near the Astros dugout, where team employees attempted to decode the pitches. When successful, a loud bang on a trash can relayed to hitters which pitch was coming their way.
