Frank Norton caught during the latter part of the season and Pearce played shortstop.
The Athletics in 1866 played all of the strongest clubs in the country and were only twice defeated, once by the Atlantics of Brooklyn, and once by the Unions of Morrisania.

The first game between the Atlantics and Athletics for the championship took place October 1st, 1866, in Philadelphia, the number of people present inside and outside the inclosed grounds being estimated as high as 30,000, it being the largest attendance known at the baseball game up to that time.

Inside the inclosure the crowd was immense, and packed so close there was no room for the players to field.

An attempt was made, however, to play the game, but one inning was sufficient to show that it was impossible, and after a vain attempt to clear the field both parties reluctantly consented to a postponement.
The postponed game was played October 22d, in Philadelphia.
The price of tickets was placed at one dollar and upwards, and two thousand people paid the "steep" price of admission, the highest ever charged for mere admission to the grounds, while five or six thousand more witnessed the game from the surrounding embankment.

Rain and darkness obliged the umpire to call the game at the end of the second inning, the victory remaining with the Athletics, by the decisive totals of 31 to 12.
