Jeffrey Scott Schaefer was a Major League Baseball player with the Chicago White Sox (1989), Seattle Mariners (1990-1992), and Oakland Athletics (1994). When Jeff, his nickname, made his big league debut on April 7, 1989, he became the first Patchogue-Medford High School graduate to play in the majors!
Major League II is a classic baseball movie that was released in theaters on March 30, 1994. Why mentioned that here? During the credits, Warner Brothers includes a "Pirate on Second Base" — that actor was Jeff Schaefer!
