The International League (IL) is a Minor League Baseball league that operates in the United States. Along with the Pacific Coast League, it is one of two leagues playing at the Triple-A level, which is one grade below Major League Baseball (MLB).

The league traces its roots to 1884, while the modern IL began in 1912. Following MLB's reorganization of the minor leagues in 2021, it operated as the Triple-A East for one season before switching back to its previous moniker in 2022. It is so named because throughout much of its history the International League had teams in Canada and Cuba as well as those in the United States. Since 2008, however, all of its teams have been based in the US. The IL's 20 teams are located in 14 states stretching from Papillion, Nebraska, to Worcester, Massachusetts, and from St. Paul, Minnesota, to Jacksonville, Florida.

A league champion is determined at the end of each season. The Rochester Red Wings have won 19 International League titles, the most in the league's history, followed by the Columbus Clippers (11) and the Baltimore Orioles, original Buffalo Bisons, and Toronto Maple Leafs (10). During the era of the Governors' Cup playoffs from 1933 to 2020, the most cup titles were won by Columbus (11), followed by Rochester (10) and the Syracuse Mets (8).

History

The International League was created from the mergers of member teams from three precursor leagues: the Eastern League of 1884, which was itself a re-organization of the Interstate Association of 1883; the New York State League, formed in 1885; and the Ontario League, also organized in 1885. The New York State League and Ontario League merged in 1886 to form the International League, and in 1887 the Eastern League was absorbed to create a ten-club league. Also in 1887, the International League passed a resolution barring African Americans from playing in the league.^[1] The league collapsed soon afterwards, when the northern teams claimed that it was too onerous to travel to the south and formed the International Association.

The "International League" name was first used in 1886,^[2] but did not become the longterm name of the league until 1912. The league ultimately cited 1884 as the year of its foundation, through the following lineage:^[3]

1884: Eastern League
1885: New York State League
1886–1887: International League
1888–1890: International Association
1891: Eastern Association
1892–1911: Eastern League
1912–2020: International League

The International League was also affected by the effort to establish the Federal League as a new third major league from 1914 to 1915, with franchises being added and dropped and new ballparks built. In 1954, a franchise was awarded to Havana, Cuba, but due to political upheaval in that country it had to be moved—to Jersey City, New Jersey—in the middle of the 1960 season. Another foray into the Caribbean failed when the newly created team in San Juan, Puerto Rico, added in 1961, had to be moved to Charleston, West Virginia, in mid-season.

In June 1971, an IL all-star team beat the New York Yankees, 15–13, in an exhibition game at Silver Stadium in Rochester, New York, before a crowd of 11,001—notable players on the all-star squad included Don Baylor, Carlton Fisk, and Bobby Grich.^[4] In August 1983, another team of IL all-stars were defeated by the Cleveland Indians, 8–6, in 11 innings before 11,032 fans at Franklin County Stadium in Columbus, Ohio.^[5]

The International League and the American Association, another Triple-A league that operated in the Midwest, voted in 1988 to play interleague games as part of the Triple-A Alliance.^[6] The league also split into two divisions that year. The interleague concept ended in 1992, but the two league divisions remained.

In 1998, the International League reorganized into three divisions with the addition of four new teams—the Buffalo Bisons, Indianapolis Indians, and Louisville Redbirds joined from the disbanded American Association, while the Durham Bulls joined from the Class A Carolina League.^[7]

The start of the 2020 season was postponed due to the COVID-19 pandemic before ultimately being cancelled on June 30.^[8]^[9] Prior to the 2021 season, Major League Baseball (MLB) assumed control of Minor League Baseball in a move to increase player salaries, modernize facility standards, and reduce travel through better geographical alignment.^[10] As part of this reorganization, the International League was expanded to 20 teams and temporarily renamed the "Triple-A East" for the 2021 season.^[10] Of these 20 teams, 14 were existing members of the International League,^[11] four were the easternmost teams from the Pacific Coast League,^[12] one was promoted from the Double-A Southern League,^[13] and one moved from the independent American Association of Professional Baseball.^[14] Following MLB's acquisition of the rights to the names of the historical minor leagues, the Triple-A East was renamed the International League effective with the 2022 season.^[15]

Structure and season

The International League is divided into the East Division and the West Division, each consisting of 10 teams. As of the 2022 season, all teams play a 150-game schedule, beginning in late March and concluding in late September.^[16]

Championship and interleague play

Since the 2023 season, the regular season is split into two halves. After the completion of the season, the winners of each half meet in a best-of-three series to determine a league champion.^[17]^[18] From 1933 to 2019, the three division champions and a wild card team squared off in series playoffs to determine a champion, with the winner awarded the Governors' Cup, the league's championship trophy.^[19] Following the cancelled 2020 season, rather than hold playoffs for its championship, the 2021 title was awarded to the team with the best regular-season record.^[20] In 2022, the two division champions met in a single game to determine a league champion.^[21]

In further postseason play, the IL champion meets the Pacific Coast League's champion in the Triple-A National Championship Game, a single game to determine an overall champion of Triple-A baseball, which has been held annually since 2006, excluding 2020 and 2021. Previously, the IL champion also competed in the Triple-A World Series (1983, 1998–2000), Junior World Series (1919), and other sporadic postseason competitions throughout the league's history.

Other interleague play occurred during the Triple-A All-Star Game. Traditionally, the game had taken place on the day after the mid-summer Major League Baseball All-Star Game.^[22] The game was meant to mark a symbolic halfway-point in the season (though not the mathematical halfway-point which, for most seasons, is usually one month prior). During the All-Star break, no regular-season games were scheduled for two days before the All-Star Game itself.^[23]

Champions

The International League has crowned a league champion each season since 1884. Through 1932, champions were the regular-season pennant winners—the team with the best win–loss record at the conclusion of the regular season. From 1933 to 2020, postseason playoffs were held to determine champions. Participants from 1933 to 1987 were usually the four teams with the highest winning percentage. From 1988 to 2020, the four qualifiers were the division winners and one or two wild card teams. The winner of each season's championship playoffs was awarded the Governors' Cup. These playoffs and the Governors' Cup trophy were discontinued in 2021. The 2021 winner was the team with the best regular-season record. The 2022 championship was decided via a single game between the winners of the East and West Divisions. Since 2023, a best-of-three series has been held between the winners of each half of the season.
