The stadium is home to the Angelo State University Rams Baseball team.

The Colts played in United League Baseball and were then the primary tenants.

Foster Field, originally named Colts Stadium, cost $3 million to construct and was built by Jim Anglea, the former head groundskeeper for the Ballpark at Arlington.

The field features 4,200 permanent seats, a Triple A lighting system and a Spectrum inning-by-inning scoreboard with video display.

The field also has artificial turf, state-of-the-art bullpens and batting cages for practice and warm-up.
