Baseball has been rocked over the last few days with the report from the Commissioner’s office on the Astros cheating during 2017.
The scandal stems from the Astros using a video feed from a center-field camera, fed through the video room that was set up to help determine whether replay review challenges should be made, or not.
This was, I suppose, an inevitable result of the challenge system. Molly Knight at The Athletic says as much in this article:
The reason we are mired in this fiasco is that MLB introduced expanded instant replay to video rooms in 2014, apparently without any inkling that teams would figure out ways to exploit this new technology to their advantage.
