The 2012 Philadelphia Spinners season was the inaugural season for the franchise, and their first and only in the American Ultimate Disc League (AUDL). The Spinners went 13-2 in the regular season to claim the number one seed in both the Eastern Conference and the league. The Spinners won the inaugural AUDL championship at the Silverdome in Detroit, MI 29-22 over the Indianapolis AlleyCats.
The 2012 season officially began on April 14, 2012 with the team's home opener at Franklin Field versus the Buffalo Hunters. The start time for the game was originally slated for at 8:05 p.m., however a large crowd of fans still entering the stadium caused the opening pull to be delayed. The game concluded with the Spinners defeating Buffalo 26-14 in front of 1,800 fans.
The season continued with a 13-2 record (with the only loses coming to the Connecticut Constitution on the road and the Detroit Mechanix at home, and one postponed game that was not re-played) and about 900 fans attending each home game. The Spinners clinched the first seed for the Eastern conference and home field advantage for the conference championship match. The Spinners were originally to play the second place Connecticut Constitution in the eastern conference championship, but due to a lawsuit, Connecticut was disqualified from the playoffs. The Spinners instead played the third place Rhode Island Rampage, who they defeated 35-21. This advanced the Spinners to the AUDL championship in Detroit at the Silverdome on August 11, 2012. The Spinners defeated the western conference champions Indianapolis AlleyCats 29-21.
