The Tacoma Rainiers of the Pacific Coast League and briefly in Triple-A West, were baseball's geographically closest Triple-A/MLB partnership for decades. The Seattle Mariners farmhands play their home games at Cheney Stadium in Tacoma, WA.
MLB's 2021 Minor League Reorganization ended that distinction by pairing the Minnesota Twins and St. Paul Saints.
Tacoma teams have played in every PCL season since 1960, with two different franchises under various nicknames - often that of their parents, except for some runs under the locally traditional pro baseball moniker "Tigers". Tacoma teams fed a total of six parent clubs before joining the M's in 1995, when they took Seattle's longtime PCL nickname.
Making the 2010 playoffs, the Rainiers made it possible for that off-season's facelift to start on time by moving their home games to Seattle's Safeco Field - its first playoff action since 2001.
The Rainiers play Copa de la Diversión Hispanic engagement campaign games as La Familia de Tacoma (Tacoma Family).
