New Hampshire Fisher Cats | 2,219 followers on LinkedIn. The Fisher Cats are the Double-A affiliate of Major League Baseball's Toronto Blue Jays. The team calls Delta Dental Stadium in Manchester, NH, its home with games played each April through late September. While there's much to be celebrated on the field and in the stands, the Fisher Cats are most proud of the impact they've had on the people of New Hampshire since arriving in Manchester for the inaugural season in 2004.
