Long time Mets fan, Jerry Seinfeld will be in the broadcast booth tonight as the Mets take on the San Francisco Giants at Citi Field.  He'll be joined by former Met first baseman Keith Hernandez who appeared in Seinfeld's sitcom for a two part episode in 1992.  This is not the first time Seinfeld has taken a crack at calling a game.  He called a Mets game in 2010, but was upset that former Met Ron Darling (who is a regular part of the broadcast team) was not working that night.  Watch the highlights from that night below.
