The error made by Bill Buckner in Game Six of the 1986 World Series is not only one of the most famous plays in New York Mets history, but it is also one of the most famous plays in MLB history.
While Buckner garners most of the blame for the incident, much more of it should be put on Boston Red Sox Manager John McNamara.
McNamara normally brought in Dave Stapleton as a defensive replacement for Buckner, but he wanted Buckner to be on the field for the game's last out. McNamara also left a struggling Calvin Schiraldi in the despite the fact that he was very ineffective.
The Red Sox managed to take a 3-0 lead in Game Seven of the World Series, but ended up losing the game and the championship.
