The International Association of Professional Base Ball Players was the name for two separate Canadian-American baseball leagues that operated from 1877 through 1880 and also from 1888 until 1890. Some baseball historians consider the International Association the first minor league; others point out that the league was conceived as a rival to the National League, now thought of as the sole major league of the era.
In 1877, the International Association featured teams based in:
The Association's by-laws and constitution required member teams to pay $10 to join the league (plus an additional $15 to compete for the championship) and fan admission was set at 25 cents. Visiting teams were guaranteed $75, plus half of the gate receipts when they exceeded that amount ($75).
Pitcher Candy Cummings was the first president of the International Association, while also a player for the Lynn Live Oaks of Massachusetts in 1877.
Jimmy Williams of Columbus served as the league's first Secretary.
London's star pitcher, Fred Goldsmith had a 14-4 record in 193 innings pitched with 3 shutouts, during International Association play in 1877.
In 1878, the league lost two teams - Guelph and Columbus - however, it added the Binghamton Crickets, Hornellsville Hornells and Syracuse Stars. The cities of Buffalo, New York, Hartford, Connecticut, Lowell, Massachusetts, New Bedford, Massachusetts, New Haven, Connecticut, Springfield, Massachusetts and Worcester, Massachusetts also had representatives. Buffalo finished in first place.
In 1878 Bud Fowler, pitching for the Lynn, Massachusetts, club, became the first known African-American player in organized baseball.
