Who was the first player in the MLB?
The first MLB was in 1871 and called the National Association. There were nine teams in the League representing the cities of Philadelphia, Chicago, Boston, Washington, New York, Troy, Ft. Wayne, Cleveland, and Rockford. Each team had 12 or 13 players, two or three being pitchers. So there really wasn’t a ‘first’ player in the MLB, it was more like the ‘first’ teams in the MLB.
