Record: 98-59, Finished 1st in National League (1951 NL)
Won NL Pennant
Managed by Leo Durocher
Ballpark: Polo Grounds IV
The 1951 New York Giants came back from being 13½ games behind the Brooklyn Dodgers on August 11th to finish tied with them after 154 games. A three-game playoff was required to determine the pennant winner, which the Giants won thanks to the "Shot Heard 'Round the World, as Bobby Thomson's game-winning homer off Ralph Branca in the bottom of the 9th in the third game came to be known. That home run has since become a cultural touchstone and is arguably the most famous home run in baseball history.
The Giants are also known for having used a sophisticated mechanism to steal opponent's signals at the [Polo Grounds]] that season. At the urging of manager Leo Durocher, coach Herman Franks took a seat behind the scoreboard and would watch the opposite catcher's signals through a telescope; he would then use a buzzer to relay what he saw through an electrical signal to the dugout, where the Giants' batter would be informed of what pitch was coming. According to the book The Echoing Green (see further reading), which revealed the scheme, the system was installed on July 20th. What is known is that the Giants were nearly unbeatable at home after that date. However, before one jumps to the conclusion that they "stole" the pennant through this devious tactic, it should also be noted that they were also a tremendous team on the road, and that their improvement between the first part of the season was in fact almost entirely based on improved pitching, and not by any better hitting. The pitching staff, which was the second worst in the National League in the first half, was the stingiest over the second half, leading to their tremendous record and ability to catch an excellent Brooklyn team down the stretch.
