There is a big difference between stealing signs through natural observation, but it’s a totally different thing when you add technology to the equation. Now that we know how the Houston Astros were cheating, I’m seeing all these Youtube videos highlighting at bats, where we hear the cans being hit for off speed pitches and nothing for fastballs. How did the home plate umpire or the opposing teams catcher, pitcher or manager not pick up on this during games? I guess I could see the opposing team not saying anything, if their doing the same thing or a variation of it, and don’t want to also lose that competitive advantage. However, there is no excuse for the home plate umpire, who should know the difference between a fastball and off speed pitch. In addition, I believe umpires are part of a crew that calls games together, but will rotate positions. Don’t these guys talk to each other and pick on cues? Or was it simply everyone involved in MLB knew what was happening but didn’t do anything until now because it wasn’t made public?
