The Green Monster is a popular nickname for the 37-foot-2-inch-high (11.33 m) left field wall at Fenway Park, home to the Boston Red Sox of Major League Baseball.
Ballparks occupied by professional baseball teams have often featured high fences to hide the field from external viewers, particularly behind open areas of the outfield where bleacher seating is low-lying or non-existent.
Some left fielders, predominantly those with vast Fenway experience, have become adept at fielding caroms off the wall to throw runners out at second base or hold the batter to a single.
And while the wall turns many would-be line-drive homers into doubles it also allows some high yet shallow fly balls to clear the field of play for a home run.
During the construction of Great American Ball Park, located right next to Riverfront Stadium, a large section of seats was removed from the center field area to make room and a 40-foot (12 m) black wall was erected as a temporary batter's eye.
As a result of the terrace, when overflow crowds were not seated atop it, a left fielder in Fenway Park had to play the territory running uphill.
[4] In contrast, rotund outfielder Bob Fothergill, known by the indelicate nicknames of "Fats" or "Fatty", reportedly once chased a ball up the terrace, slipped and fell, and rolled downhill.
In 1934, Red Sox owner Tom Yawkey arranged to flatten the ground in left field so that Duffy's Cliff no longer existed, and it became part of the lore of Fenway Park.
[6] Carlton Fisk's "body English" when he hit his game-winning home run in Game 6 of the 1975 World Series, "waving" the ball fair, was captured on a TV camera stationed in the scoreboard.
The Morse Code that appears from top to bottom in the white lines of the American League scoreboard are the initials of former owners Thomas A. Yawkey and Jean R.
The bullpen was added along the right field wall in 1940 to shorten the distance for left-handed slugger Ted Williams' home runs to clear the fence.
In 1936, the Red Sox installed a 23-foot (7.0 m) net above the Monster in order to protect the storefronts on adjoining Lansdowne Street from home run balls.
Comprising yet another quirk, a ladder is attached to the Green Monster, extending from near the upper-left portion of the scoreboard, 13 feet (4.0 m) above ground, to the top of the wall.
Above the manual scoreboard, where a Jimmy Fund advertisement had remained for many years, the logo for Foxwoods Resort Casino is now a prominent aspect of Fenway Park.
