ガルフ・コーストリーグ
From 1979–1981, the Royals operated two GCL teams, the Gulf Coast League (GCL) Royals Blue and Gulf Coast League (GCL) Royals Gold, to accommodate a surplus of teenaged players. In 1974, Kansas City also fielded a separate Gulf Coast League (GCL) Royals Academy team for members of its experimental Baseball Academy. The Academy team played alongside the GCL Royals; finishing 35–16 in the GCL standings that season, 4½ games ahead of the 29–19 GCL Royals, but the Royals Academy lost the league pennant by percentage points to the GCL Cubs.
