Glens Falls and Cooperstown were the regular season division champions in the PGCBL East and West respectively.

The two-division format was replaced by a single nine-team division with the top four teams in the league regular season standings qualifying for the playoffs.

The Adirondack Trail Blazers and the Utica Brewers joined the PGCBL in the fall of 2012 while the Oneonta Outlaws were granted a one year Voluntary Suspension of operations.

Albany, Cooperstown, Glens Falls, Mohawk Valley and defending champion Amsterdam formed the East while newcomers Adirondack and Utica joined Elmira, Newark and Watertown in the West.

Three seeds Albany and Elmira each won opening round playoff games over second-seeded Mohawk Valley and Newark respectively to advance to the divisional finals against Amsterdam and Watertown.

Amsterdam edged out Albany and Elmira in back-to-back Game 3's to become the first repeat champion in league history.

In July 2014, the league announced a franchise will be placed in Saugerties, New York and play in the East Division-effective for the 2015 season.

Both teams were upset in the divisional round of playoffs as Mohawk Valley upended the defending champions in three games, while the first year Victor RailRiders swept the Pioneers.

The Mohawk Valley DiamondDawgs then swept the RailRiders to capture the 2015 PGCBL Championship, the first in team history.

Amsterdam went back to the PGCBL Finals to meet Utica, who was making their first trip in franchise history.

Amsterdam then swept the PGCBL finals with two decisive victories to earn their fourth title in five years.

Saugerties earned the number four seed in the East, while Geneva bounced back from a 9-40 season to get a home playoff game in the West.

Mohawk Valley then dethroned Amsterdam for the second time in three seasons to set up a PGCBL Finals with the Jamestown Jammers.

In October 2018, the defending champion Jamestown Jammers abruptly announced they were ceasing operations after the Milwaukee, Wisconsin-based ownership group pulled out of the league in favor of setting up an American Association of Independent Professional Baseball team in its home city.

[citation needed] For the 2022 season, the PGCBL switched from the three-division format back to two divisions, East and West,[6] and the Adirondack Trail Blazers were renamed the Boonville Baseball Club.
