For the 2015 season, the Mets moved in portions of Citi Field's center and right-center walls. The changes range from three to 11 feet.
This is in addition to the alterations made after the 2011 season when the outfield wall in leftfield and rightfield moved closer to home plate. Those changes ranged from approximately 4 feet in leftfield and up to approximately 12 feet in deep left-centerfield. The height of the home run line was also lowered to 8 feet throughout the outfield. The distances from home plate to centerfield and the foul poles in leftfield and rightfield have remained the same since the ballpark opened in 2009.
The new dimensions (380 in rightcenter and 370 in right) are similar to those at Shea Stadium (396 in rightcenter and 371 in right).
