The Cotuit Athletic Association was organized in 1947, primarily as a sponsor for the KETTLEERS baseball team, was chartered in Massachusetts as a non-profit 501(c)(3) organization in 1962, and has grown tremendously in its scope since that time.

CAA members fully maintain the Lowell Park baseball facility (field maintenance and capital improvements), finds housing and jobs for the 26 team members and coaches, provides uniforms and baseball equipment for a 44-game schedule, and operates three baseball/softball clinics for youngsters. The Association gives college scholarships of $750 to local residents, awards MVP trophies in both baseball and hockey, donates baseball clinic camperships to six children from Big Brothers/Big Sisters of Cape Cod, and sponsors 7 baseball/softball teams in local community recreation departments. For its efforts the Cotuit Kettleers were selected by the Cape Cod Baseball League as the first recipient of its Franchise of the Year Award in 1990 and in 2000 was named the Best Amateur College Program of the Decade by Baseball America. In 2006, Cotuit was named the best summer team in the nation by Baseball America.

The officers and members of the Cotuit Athletic Association devote their time and energy as volunteers, working year around to raise funds and organize activities which provide the enjoyment of baseball games in the community every summer.
