New England roots The modern Harrisburg Senators originated in the New England states. First established in 1976 as an affiliate of the
Milwaukee Brewers, the
Berkshire Brewers played one season in
Pittsfield, Massachusetts. After that season, they moved to
Holyoke, Massachusetts, where they took the nickname the
Millers. In 1981, the franchise changed affiliations, moving from the Brewers to the
California Angels. After the 1982 season, the team relocated to
Nashua, New Hampshire, as the
Nashua Angels. After the 1983 season, the team's affiliation changed again, this time to the
Pittsburgh Pirates. The team changed its name then to the
Nashua Pirates. At the same time, during the mid-1980s, Harrisburg Mayor
Stephen Reed initiated a revitalization plan that included
a ballpark for a new Minor League Baseball team in the city. The Nashua Pirates relocated to Harrisburg and was rechristened the Senators on
December 9, 1986.
The Senators Like the original Senators, success was quick, winning the
Eastern League championship in its first season. In 1991, affiliation shifted from the Pittsburgh Pirates to the
Montreal Expos, an affiliation continuing through that team's move to Washington, D.C., where they continued as the
Washington Nationals. The first several years of affiliation with Montreal brought consecutive championships from 1996 to 1998. In 1999, the Senators played the Norwich Navigators for a shot at their record-setting fourth consecutive Eastern League championship. In the bottom of the ninth inning of game 5, the Senators trailed by 3 runs, but with 2 outs, the bases loaded, and a full count
Milton Bradley hit a walk-off grand slam to right center field to win the fourth-straight championship for the Senators, an Eastern League first. In 2003, Sueng Song pitched the first no-hitter in modern Senators history. In conjunction with Major League Baseball's restructuring of Minor League Baseball in 2021, the Senators were organized into the Double-A Northeast. In 2022, the Double-A Northeast became known as the Eastern League, the name historically used by the regional circuit prior to the 2021 reorganization. ==Uniforms and logo==
