Here's the official release from the Mets:
The New York Mets today announced that original Met and Mets Hall of Fame broadcaster Ralph Kiner will throw out the ceremonial first pitch prior to the Mets Home Opener at Citi Field, this Friday, April 8 when the Mets host the Washington Nationals at 4:10 p.m.
Kiner, inducted into the National Baseball Hall of Fame in 1975, celebrates his 50th season broadcasting Mets games this year. Kiner was part of the original Mets broadcast team which included Bob Murphy and Lindsey Nelson. In 2002, Shea Stadium’s TV booth was named in Kiner’s honor and Citi Field’s home television booth also bears his name. He was inducted into the Mets Hall of Fame in 1984.
More than 140 veterans representing all five U.S. Armed Services – Army, Air Force, Coast Guard, Marines and Navy – will be on the field during the pre-game presentation of a giant American flag. Michael Amante, a New York native and an acclaimed tenor, will sing the National Anthem prior to the game.
The first 25,000 fans in attendance will also take home a Mr. Met Bobblehead presented by Citi.
