Jack Rafter played one game in the majors in 1904.
He is listed as having been at Fordham University from 1894-1904, presumably not during all that time, and started in the minors apparently in 1894. He moved around a lot but played parts of five seasons with Troy, three with Syracuse and three with Albany.
He was born and died in Troy, NY.
