Allie P. Reynolds Stadium has a listed capacity of 3,281 people and was opened April 4, 1981, against then-Big 8 foe Missouri.

Allie P. Reynolds will be replaced by the new O'Brate Stadium, aimed at attracting Super Regional round games.

The new ballpark has a permanent capacity of 3,500, slightly smaller than that of Reynolds, but is expandable to 8,000 for major events such as NCAA tournament games.

The Cowboys had planned to play their first 14 home games of the 2020 season at Reynolds, ending on March 15 with the last of a three-game series against Fresno State.
