Buffalo Bisons

The Buffalo Bisons carry a baseball heritage that few minor league teams can match. Professional baseball in Buffalo dates to the 1870s, and the current franchise — established in 1979 when a group led by Mayor James D. Griffin purchased the Jersey City A's for $55,000 — inherited that legacy when it took the Bisons name. When Robert E. Rich Jr. purchased the team for $100,000 in 1983, he set in motion a transformation that would make Buffalo one of the crown jewels of the minor leagues.

Rich upgraded the Bisons to Triple-A in 1985 by acquiring the Wichita Aeros, and the construction of Pilot Field (now Sahlen Field) in downtown Buffalo in 1988 ushered in a golden era. The Bisons shattered attendance records, drawing a minor league record 1,240,951 fans in 1991 as the city made its case for Major League Baseball expansion. Though the expansion bid fell short, the Bisons had established themselves as a model franchise. The team won three league championships (1997, 1998, 2004) and ten division titles across its affiliations with Cleveland, Pittsburgh, and the New York Mets.

The franchise's connection to the Toronto Blue Jays, which began in 2013, reached an extraordinary chapter when the COVID-19 pandemic forced the Blue Jays to use Sahlen Field as their home park in 2020 and 2021. The arrangement brought major league baseball to Buffalo for the first time in over a century and led to significant stadium upgrades funded jointly by the Bisons and Blue Jays. Eighteen members of Toronto's 2025 World Series roster played for the Bisons under manager Casey Candaele, a testament to Buffalo's role as the final proving ground for Blue Jays prospects.

The Bisons' alumni list reads like a wing of the Hall of Fame — since 1937, twenty-one former Bisons players, managers, or coaches have been inducted at Cooperstown, including Johnny Bench, Ferguson Jenkins, and Jim Thome. More recently, Vladimir Guerrero Jr. and other Blue Jays stars have passed through Buffalo on their way to the big leagues. Under the continued ownership of the Rich family, the Bisons remain one of Minor League Baseball's flagship organizations, drawing fans to their downtown ballpark in the shadow of the Buffalo skyline.
