Who is this Les Gomez person?

Hi. I'm new to baseball, so sorry if I sound stupid. Last night, I was watching the New York Mets game and they played the Florida Marlins. At several points in the game, I heard some chants by the crowd. It sounded like they were saying "Les Gomez!" And i checked the Mets and Marlins roster and there is nobody named Les Gomez there. So, who is Les Gomez? Was he just some fan making a racket, or is he a former player or prospect? Can somebody please tell me. Thank You.
