Before his sole major league season of 1875, John Abadie was the starting first baseman for the Eastons, a semipro team from Easton, PA that, in 1874, had defeated three major league caliber opponents - the Philadelphia Athletics, the Philadelphia Whites and the Brooklyn Atlantics. With such success, they were a natural pool of talent to draw from when the National Association expanded from 8 to 13 teams in 1875. Abadie's teammates on the Eastons in 1874 who had also previously played on major league rosters or would included pitchers George Bradley, Bill Parks, and Jim Devlin, catcher Tom Miller, third baseman Joe Battin, and shortstops Denny Mack and Chick Fulmer. With an equally large contraction back down to 8 teams in 1876, Abadie and many others were kicked back to semipro ball permanently. Abadie had been the first player listed alphabetically until Hank Aaron's debut in 1954.
