4. Astros Sign-Stealing
The Astros’ sign-stealing scandal continues to hang over MLB like a noxious gas of a shadow. It’s still ridiculous that the league failed to strip Houston of their titles after blatant cheating. Meanwhile, they scapegoated the Astros’ GM and head coach when the players were responsible (via N.Y. Times).

Allegedly, it was an open secret that the Astros were sign-stealing. The aftermath of this situation had serious ramifications for MLB. It was a giant mess because it should never have been allowed to happen. Also, even Houston fans lost faith because their team represented the city so poorly.
