This is just a higher tech version of how the Giants came back from 14 or 15 games back in 1951, capped by the "Shot heard 'round the world", Bobby Thompson's home run against Ralph Branca.
Bobby Thompson (s Staten Islander, I just learned while visiting the incredible CYO facility there), knew what Branca was doing to throw. The Giants had a lookout in the scoreboard with binoculars, who would signals the bullpen, who had a buzzer to the dugout indicating the pitch. The third base coach, Leo Druchoer would then signal the batter, perfected all to a couple of seconds.
Branca, who was continually booed at public appearances for many, many years, found out about the cheating in 1954. Despite being one of the great young National league pitchers, he tried to come back from an arm injury too soon to shake the label of "bum", and damaged his arm. He was discarded to Cleveland, where the backup catcher from the Giants had also landed, and who told him of the cheating. Branca, not wanting to be labeled a whiner, kept his mouth shit for over 50 years until a book about how the Giants stole the pennant was published. He tried to get MLB to invalidate the pennant and give the Dodgers NL championship rings, which they would not do.
MLB should act quickly to strip the Astros of their accomplishments. This is systemic cheating endorsed by the organization, not a baserunner trying to steal a sign and relaying it
