After the 2011 season the Mets moved in portions of the outfield wall at Citi Field as much as 12 feet and lowered the height of the home run line to 8 feet throughout the outfield. The outfield wall became blue in 2012 concurrent with the Mets 50th Anniversary season. The home run line and distance markers remained orange.
The Mets erected a new wall in leftfield starting between the New Era and Caesars signs and angled to the Citi sign in left-centerfield (see renderings below). The new wall is closer to home plate by approximately 4 feet in leftfield and up to approximately 12 feet in deep left-centerfield.
The new wall starts in right-centerfield and extends toward the bullpen, and is as much as approximately 11 feet closer to home plate. The fence in front of the Mo's Zone/Modell's Clubhouse moved in approximately 10 feet. The distances from home plate to centerfield and the foul poles in leftfield and rightfield remained the same.
