This nice 2001 World Series game-used on-deck circle measures 56 inches in diameter. It was used in Arizona when the Diamondbacks defeated the Yankees in the World Series in seven games. This particular series was delayed by the terrible events of September 11, and began at the end of October, 2001. Game 3 was opened by President George W. Bush, who threw out the ceremonial first pitch. This is a great item for the floor of a sports collection room. MLB hologram.
