I don't see anyone in the group that resembles Marty Bergen and to my knowledge he never played for Princeton. He was playing for his town team prior to 1892 when he started his professional career with Salem of the New England League. He spent four years in the minors, then moved on to the majors from 1896 thru 1899 with the Boston Beaneaters.
