Eric Anthony Duncan is an American former professional baseball second baseman and quality control coach for the Miami Marlins of Major League Baseball (MLB). Considered an excellent high school baseball player, Duncan was chosen by the New York Yankees in the first round of the 2003 MLB draft, and became one of the best prospects in baseball. However, injuries and ineffectiveness in minor league baseball prevented Duncan from reaching MLB.

Seton Hall Preparatory School, generally called Seton Hall Prep, SHP, or "The Prep", is a Roman Catholic all boys' high school located in the suburban community of West Orange in Essex County, in the U.S. state of New Jersey, operating under the supervision of the Archdiocese of Newark. Founded in 1856 with an original enrollment of five boys, Seton Hall Prep was originally located on the campus of Seton Hall University, where it became commonly known as "The Prep" as a way to distinguish it from "The University." In 1985, the school moved to its present location which was, at the time, West Orange High School. Seton Hall is the oldest Catholic college preparatory school in New Jersey.
