Press release from Mets.com:
FLUSHING, N.Y., April 11, 2009 - The New York Mets today announced that Hall of Fame pitcher Tom Seaver will throw out Citi Field's inaugural ceremonial first pitch to All-Star catcher Mike Piazza prior to the Mets Home Opener, this Monday, April 13 vs. the San Diego Padres at 7:10 p.m.
Seaver, the club's all-time leader in wins, ERA, strikeouts, and innings pitched, will be reunited with Piazza, who ranks second in team history in home runs and RBI. Seaver and Piazza closed the centerfield gate following the Mets final game at Shea Stadium September 28 last year.
The cast of the Broadway revival West Side Story will perform the National Anthem. The uniquely New York classic opened on Broadway in 1957 when New York had two National League baseball teams.
More than 200 veterans representing all five U.S. Armed Services - Army, Air Force, Coast Guard, Marines and Navy - will be on the field during the presentation of a football field-size American flag. The Anthem will conclude with a flyover by four U.S. Marine F18 Hornets from VMFA 251 based in Beaufort, S.C.
The Empire State Building will light its world-famous tower in orange and blue to commemorate the opening of the Mets' new home. Monday's 7:10 p.m. game will be broadcast live in Rockefeller Center at SNY's Studios and carried on ABC Television's SuperSign above their Good Morning America studio in the heart of Times Square.
Emphasis mine.
Please, just for a moment imagine Jake Peavy and the Padres facing off against Johan Santana and the Mets, snapping and dancing in this video.
It’s quite humorous if you have a vivid imagination.
