[4] Primary seating at MacLean was in the wooden grandstand along its east bank; the Memorial Gymnasium (1928) was to the northwest and the Shattuck Arboretum bounded it on the south.

The baseball infield was originally all-dirt and in MacLean's southwest corner, near Rayburn Street, with the Mem Gym as a left field backdrop.

[15] The southern portion of the permanent football seating, adjacent to left field,[16] was excess capacity for baseball and was removed during World War II.

A multi-purpose fieldhouse was constructed on the old southwest infield in the late 1940s;[21] it was razed after the enclosure of the Kibbie Dome in 1975, and is now the site of outdoor tennis courts (south).

The final varsity baseball games at MacLean were on Saturday, May 14; the Vandals swept a doubleheader with Montana State to finish at 11–1 in conference play and secured a second Big Sky title in three seasons.

[27][28] Construction of the new College of Education building commenced behind home plate,[29][30] and the baseball field was moved to the northwest area of campus,[23] just south of Paradise Creek (and Pullman Road) (46°43′54″N 117°01′10″W / 46.7316°N 117.0195°W / 46.7316; -117.0195).
