Each year during the Pine Island Cheese Festival, which occurs on the first weekend in June, the Pine Island Baseball Association hosts a one-day baseball tournament with 5th grade (11U) and 6th grade (12U) divisions. Normally PIBA hosts a six-team tournament for each grade level. The tournament format is round robin three-team pool play followed by a one game playoff bracket with match ups of like finishers from the two pools playing each other. The tournament format may change based on the number of teams that register for the tournament.

The classic tournament has been an annual event during Pine Island Cheese Festival since 2009.
