Wally the Green Monster is the official mascot for the Boston Red Sox. His name is derived from the Green Monster, the nickname of the 37-foot 2-inch wall in left field at Fenway Park. Wally debuted on April 13, 1997. Although he was an immediate success with children, he was not as well-received by older fans. Wally has since become more accepted by Red Sox fans of all ages, in part due to the late fan-favorite Red Sox broadcaster Jerry Remy creating stories about him and sharing them during televised games.
