Eastern League (1938–present)

The Eastern League (EL) is a Minor League Baseball (MiLB) sports league that has operated under that name since 1938, with the exception of the 2021 season, during which the league operated under the moniker Double-A Northeast. The league has played at the Double-A level since 1963, and consists primarily of teams located in the Northeastern United States.

History
The league was founded in 1923 as the New York–Pennsylvania League. The first team outside the two original states was created in 1936 when the York White Roses of York, Pennsylvania, moved to Trenton, New Jersey, and were renamed the Trenton Senators. The league was renamed as the Eastern League in 1938 when the Scranton Miners of Scranton, Pennsylvania, moved to Hartford, Connecticut, and became the Hartford Bees.

The league has had teams in a total of 52 different cities, located in 12 different states and two Canadian provinces. The league consisted of six to eight teams from 1923 until 1993. The league expanded to 10 teams in 1994 with the addition of the Portland Sea Dogs and the New Haven Ravens and split into two divisions, the Northern Division and the Southern Division. The league expanded to 12 teams in 1999 with the addition of the Altoona Curve and the Erie SeaWolves. The two divisions were restructured and renamed for the 2010 season as the Eastern Division and the Western Division because the Connecticut Defenders moved to Richmond, Virginia, after the 2009 season, becoming the Richmond Flying Squirrels.

The start of the 2020 season was postponed due to the COVID-19 pandemic before ultimately being cancelled.

As part of Major League Baseball's 2021 reorganization of the minor leagues, the league was temporarily renamed the "Double-A Northeast"; the Somerset Patriots, formerly an independent team, joined the league, while the Trenton Thunder were relegated to the newly-formed MLB Draft League. Following MLB's acquisition of the rights to the names of the historical minor leagues, the Double-A Northeast was renamed the Eastern League effective with the 2022 season.

Champions
League champions have been determined by different means since the Eastern League's formation in 1923. Before 1934, the champions were simply the league pennant winners. A formal playoff system to determine league champions was established in 1934.

The Binghamton Triplets have won 10 championships, the most among all teams in the league, followed by the Elmira Colonels/Pioneers/Royals (8) and the Scranton Miners/Red Sox (7). Among active franchises, the Akron Aeros/RubberDucks and Harrisburg Senators have each won 6 championships, the most in the league, followed by the Reading Fightin Phils (4).
