3. The Steal Heard Round the World
It's the most famous home run in Major League history: Bobby Thompson's "shot heard round the world," which won the 1951 pennant for the New York Giants. But did Thompson have advance knowledge of what pitch he would be thrown? According to a 2001 investigation by the Wall Street Journal, the Giants relied on an elaborate sign-stealing scheme that season, using a confederate in center field armed with a spyglass to read the catcher's signals and then relay the information to the bench electronically. When the Giants left New York, the suspicions died with the team name.
