Jerry Seinfeld set to join announcer's booth in Tuesday's Mets game

It might be a baseball game about nothing -- and not just because the Mets are playing.

Jerry Seinfeld is set to join Gary Cohen, Ron Darling and Keith Hernandez in the announcer's booth for Tuesday's Mets game against the San Francisco Giants.

Seinfeld, 59, is a lifelong Mets fan -- the team was a constant presence on "Seinfeld" -- and has joined the booth as a guest analyst once before, announcing a single inning in 2010.

First pitch in Tuesday's game is at 7:10.
