The 30-year run of Triple-A baseball in Colorado Springs will end in 15 months.

The Elmore Sports Group announced Wednesday it is responding to “pressure from within Major League Baseball” and moving the Triple-A Sky Sox to San Antonio for the 2019 season and replacing it in Colorado Springs with the short-season Rookie-level team currently in Helena, Mont.

The Double-A San Antonio Missions will move to a new ballpark in Amarillo, Texas.

The Elmore Sports Group owns the three relocating teams.

The possibility of this move was reported by The Gazette in Jan. 2016, and the Elmore family appeared with a team mascot before the San Antonio city council a few months later to announce intentions to relocate to the Alamo City. But the transaction was dependent upon the contingency of San Antonio building a new ballpark to house the Triple-A franchise.
