The Jamestown Jammers are a minor league baseball team in Jamestown, New York, United States. The team is the Short-Season A classification affiliate of the Pittsburgh Pirates and plays in the New York - Penn League. The Jammers' home field is Russell Diethrick Park in Jamestown.
The Jammers are co-owned along with the Buffalo Bisons by Bob Rich, Jr., owner of Rich Products. Despite the co-ownership and proximity, the two teams have never been affiliated with the same parent club at any time in their history and have thus always been in separate farm systems.
The team was preceded in Jamestown by the Jamestown Falcons (initially known as the Jamestown Jaguars) and the Jamestown Expos.
The team was previously based in Niagara Falls, New York as the Niagara Falls Rapids, a Detroit Tigers affiliate. Their home stadium in Niagara Falls was Sal Maglie Stadium. The team played in Niagara Falls from 1989-1993. In 1994 the team moved to Jamestown, and became the Jamestown Jammers. The Jamestown Expos had left the city after the 1993 season, relocating to Vermont. The new team was named the "Jammers" after a fan vote, with the winning name beating out others such as the All-Americans, Furniture Makers, Jimmies, Lakers, Lucys, Muskies and Steamers. The team's logo was a Tasmanian Devil-esque character. The mascot was a similar character named J.J. Jammer.
In the off-season before the 2006 season, in an attempt to put an end once and for all to the "what is a Jammer?" questions, the Jammers changed their logo to a cartoon grape theme. The new logo represents the strong tradition of grape-growing in Chautauqua County. On June 19, 2006, the eve of opening day, the team officially announced the name of its new mascot: Bubba Grape, the Baseball Ape.
Published reports released in March 2013 indicated that the Jammers were the leading candidate for relocation after the league announced it would be relocating one of its franchises to the campus of West Virginia University in Morgantown, West Virginia in 2015. Neither the team nor the league confirmed or denied the reports.
