Over the ten years of their existence, the Athletics were a successful club on the field, winning 633 games and losing 564, for a winning percentage of .529. The team won the AA pennant in 1883, finishing one game ahead of the St. Louis team. That same year, however, the National League set up its own team in Philadelphia, the Philadelphia Quakers (later Phillies). The Quakers finished last in 1883, but soon improved on the field and at the gate.
