Last week the Houston Astros’ (who eliminated the Tampa Bay Rays in the 2019 ALDS) manager AJ Hinch and GM Jeff Luhnow were suspended for one year by the commissioner’s office and subsequently terminated by Astros’ owner, Jim Crane.
This was a result of Major League Baseball’s investigation into claims that the Astros had organized a high-tech sign-stealing system.
They had a live camera feed running to a monitor just outside the dugout and would make noises by banging on trash cans (or other methods) to notify the hitters of pitch type.
One of the ring leaders was bench coach, Alex Cora.
