Stealing signs is a part of baseball. There are no ifs, ands, or buts about it. If your team has a man on second and that runner can somehow crack the code of a flurry of signs from the catcher, as well as relay them in time, it is well within his right to let the hitter know what pitch is coming. The Houston Astros are not alone in the pursuit of other team’s signs.
Well apparently in 2017, the Houston Astros crossed the line in their pursuit of that competitive advantage.
In an article written by Ken Rosenthal and Evan Drellich of The Athletic, four ex-Astros’ players revealed that they had direct knowledge of a sign-stealing scheme.
