No one can forget the Houston Astros' sign-stealing scandal in 2017. The team used cameras to record the signs of opposing catchers. This information was then relayed to their own players, alerting them to what kind of pitches would be arriving.
In November 2019, The Athletic wrote an article detailing the scandal with testimony from Mike Fiers, a former Houston Astros pitcher. This led to MLB investigating the incident and in 2020 announcing that the Astros had indeed cheated.
This resulted in the suspension of the field manager, A.J. Hinch and the general manager of the Astros, Jeff Luhnow.
In October 2020, Luhnow gave an interview with Click2Houston, where he expressed regret about the Astros' actions.
"It was wrong, and it should never have happened, and I’m upset. I’m really upset that it happened," he said. "I’m upset for our fans, I’m upset for players on other teams that gave up hits as a result of this that should never have happened. If we won games because of it, it should never have happened, and we didn’t need to do it.
"We had a great team. The team we put together in 2017, a lot of which is still together today, is one of the best teams of the 21st century, and has had an incredible stretch. And there’s no reason why we needed to explore breaking the rules to gain an advantage, it made no sense to me.”
"It’s not a day I ever want to re-live" - When former Houston Astros GM spoke about the consequences of cheating
In the same interview, Luhnow was asked how his life changed after the scandal. Luhnow said he never wanted to think about the incident again.
"It’s not a day I ever want to re-live, and it’s not a day I would ever want even my worst enemy to have to live through."
The Houston Astros were fined $5 million and had to forfeit future draft picks as punishment.
