[1] In October 1903, Kisinger was traded by the Tigers with other players to the Buffalo Bisons of the Eastern League for Cy Ferry and Matty McIntyre.

Time and again has he proved this, and his sunny disposition, his German – coupled with his ability to play the game makes him the valuable player that he is to the Buffalo baseball club.
