The Eastern League is a Minor League Baseball league, which operates primarily in the northeastern United States, although it has had a team in Ohio since 1989. The Eastern League has played at the Double-A level since 1963. The league was founded in 1923, as the New York–Pennsylvania League. In 1936, the first team outside the two original states was created, when the York White Roses of York, Pennsylvania, moved to Trenton, New Jersey, and was renamed the Trenton Senators. In 1938, when the Scranton Miners of Scranton, Pennsylvania, moved to Hartford, Connecticut, and became the Hartford Bees, the league was renamed the Eastern League.
Since 1923, there have been Eastern League teams in 51 different cities, located in 12 different states and two Canadian provinces. The league consisted of six to eight teams from 1923 until 1993. In 1994, the league expanded to 10 teams, 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. In 1999, the league expanded to 12 teams, 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, where they are now known as the Richmond Flying Squirrels.

The Cardinals played at Fairview Field until 1948, when they moved into the new Breadon Field, a steel and concrete stadium that seated 5,000 fans, which was located just north of the city in Whitehall Township. Poor attendance led to the teams demise after the 1956 season.Allentown Chiefs

Double-A (or Class AA) is the second highest level of play in Minor League Baseball (MiLB) in the United States after Triple-A. There are thirty Double-A teams in three leagues at this classification: Eastern League, Southern League, and the Texas League. The modern Double-A classification was created in 1946 with the renaming of Class A1, which then contained the Texas League and the Southern Association. After the Southern Association disbanded in 1961, the Eastern League and the original South Atlantic "Sally" League were bumped up to Double-A in the 1963 minor league reorganization. The SAL changed its name to the Southern League in 1964.Eastern League (1916)
Not to be confused with the Eastern League (1884), which functioned from 1884 until 1887 or the current Eastern League (baseball)The Eastern League of 1916 through the mid-season of 1932 was an American minor baseball league and the third of four circuits to use the "Eastern League" name since the 19th century. The successor to an early 20th-century edition of the New England League, it is not related to the current Eastern League, which formed in 1938 from the former New York–Pennsylvania League, or the current International League, which was known as the Eastern League from 1892 through 1911.
The Eastern League of 1916–32 was a mid- to higher classification league, beginning in 1916 as a Class B circuit and upgraded to Class A in 1919. Its president, Tim Murnane, a former sportswriter, and many of its original member clubs were inherited from the New England League, which ceased operation in 1915. While most of its teams were centered in New England and upstate New York, in its later years the Eastern League admitted teams from Pennsylvania and Virginia. The league consisted of eight teams annually during its existence. The New Haven franchise, owned and operated by George Weiss from 1919–29, won four of its 17 championships — though under multiple nicknames. Weiss would go on to a Baseball Hall of Fame career as a top executive with the New York Yankees.
This edition of the Eastern League collapsed during the nadir of the Great Depression on July 17, 1932.Eastern League rosters

The International League (IL) is a Minor League Baseball league that operates in the eastern United States and is headquartered in Dublin, Ohio. Like the Pacific Coast League and the Mexican League, it plays at the Triple-A level, which is one step below Major League Baseball.
It was so named because throughout its history the International League has had teams in Canada and Cuba as well as those in the United States. However, since the relocation of the Ottawa Lynx to Allentown, Pennsylvania, to become the Lehigh Valley IronPigs for the 2008 season, all of the league's teams are now based in the U.S. Today, the league is composed of 14 teams across 9 states stretching from Indianapolis, Indiana, to Pawtucket, Rhode Island, and from Rochester, New York, to Lawrenceville, Georgia.
A league champion is determined at the end of every season. The Rochester Red Wings have won 19 International League titles, the most in the league's history, followed by the Buffalo Bisons (12) and the Toronto Maple Leafs (11). Since the introduction of the Governors' Cup in 1933, the most cup titles have been won by Rochester and the Columbus Clippers (10), followed by the Syracuse Mets (8) and the Montreal Royals (7). After the season, the IL champion plays in the Triple-A National Championship Game against the Pacific Coast League champion to determine an overall champion of Triple-A baseball. The Columbus Clippers and Durham Bulls have each won two national championships, more than any other IL team.New Hampshire Fisher Cats

They won their first-ever title on September 17, 2006, defeating the Akron Aeros, 8–5, in a rematch of the series from the previous year.
