The Mets announced on Thursday afternoon that they have relocated their retired numbers to a more visible section of Citi Field.

The retired numbers are now located above the upper deck in the leftfield corner, extending from Sections 531 to 534.

The retired numbers had been located near the M&M’s Sweet Seats and behind the leftfield wall. The Mets, however, moved the leftfield wall in after the 2011 season — the first of two alterations at Citi Field — and put a single row of seats in front of the retired numbers, interfering with the visibility of the numbers for some fans. The M&M’s Sweet Seats is also an area where fans congregate.

“The combination of our increased attendance coupled with the retirement of Mike Piazza’s number brought to light the need to enhance the visibility for all of our retired numbers, which were frequently obstructed in their previous location,” the Mets said in a statement.

The Mets will honor Piazza and retire his number on July 30. The other retired numbers for the Mets include the No. 41 of Hall of Fame pitcher Tom Seaver; the No. 14 of Gil Hodges, who managed the Mets to the 1969 World Series championship; the No. 37 of Hall of Famer Casey Stengel, who was the Mets’ first manager in 1962; and the No. 42 of Jackie Robinson, which is retired throughout baseball. A microphone for longtime Mets broadcaster Ralph Kiner and the word “Shea,” in honor of the contributions to the franchise of William Shea, who helped bring National League baseball back to New York, are also among the retired numbers.
