" Nearly all of the surviving Giants, including Thomson, confessed to as much in 2001, Joshua Prager writes in the Wall Street Journal. The Giants had a buzzer installed in its center-field clubhouse at the Polo Grounds, their home field. The person at the telescope would watch the catcher, then push the buzzer once for fastball, twice for an off-speed pitch. It sounded in the team's right-field bullpen, where the batter would look as a player relayed the sign. "

You don't know about cheating in baseball? Pine tar, corked bats, steroids, drugs (A-Roid for one) etc? Yeah, I know there is a difference in just "stealing" signs and cheating for signs. But treating ANY pro athlete NO matter what sport like they are heroes is wrong. Pro sports should not be what we use to teach our kids. Does demeaning other fans and name calling and hatred toward another team teach a kid anything useful?
I am a die hard BB fan who used a be an Astros season ticket holder when I had a downtown job. But it doesn't define who I am. It's just a game.
