He was with the amateur Chicago White Stockings before the National Association started, and played for them in 1871 when the new league began. He is remembered for being one of the players who tied for the league home run lead with four.
Fred, an outfielder, had his best year in 1871. After that, his hitting was below average, and he moved around among various teams, never playing more than one year in a row for the same team - although he did play for three different teams in Philadelphia, and played twice for the White Stockings and the Philadelphia Whites.
