Multi-sport.
MacLean's football field was conventionally oriented north-south, with the west sideline approximately aligned with the Memorial Gym's In its early years, the grandstand on the east berm had limited seating, between the 40-yard-lines. By the late 1920s, permanent seating extended to the end zones and the west sideline had temporary seating along much of its length. Prior to 1914, the football team played in north Moscow, at the southwest corner of Main and E streets.
The baseball infield was originally all-dirt and in MacLean's southwest corner, near Rayburn Street, with the Mem Gym as a left field The running track, a rounded square around the football field and adjoining practice field, ran through portions of center and right field.

Baseball only.
MacLean Field was the primary outdoor venue for the university until the addition of Neale Stadium in autumn 1937. Football moved to the new stadium to the west, and the baseball infield was relocated from MacLean's southwest corner to the opposite northeast corner for the 1940 season, with the east grandstand along its third base line. The southern portion of the permanent football seating, adjacent to left field, was excess capacity for baseball and was removed during World War II. Track and field continued at MacLean until after the war.
The new alignment had abundant foul territory, especially along the third base line. Other than a backstop, there was little foul territory fencing, except to protect a parking lot to the right; it also went without dugouts, as the teams sat on open benches. Later seasons employed a low temporary outfield fence, and tennis courts (mid-1950s) in right field provided a higher permanent barrier; the distance down the left field line in 1959 was The approximate location of home plate was ().
A multi-purpose fieldhouse was constructed on the old southwest infield in the late 1940s; it was razed after the enclosure of the Kibbie Dome in 1975, and is now the site of outdoor tennis courts (south). In the new baseball alignment, it was in deep right center the left field backdrop to the south was Shattuck Arboretum, and the berm between it and the outfield provided an elevated seating area.
Final season.
The successful 1966 baseball season was the last at MacLean Field, and the Vandals were 31–7 () in the regular season. Led by future major league pitcher Bill Stoneman, they advanced to within a round of the College World Series.

Move to Guy Wicks Field.
Construction of the new College of Education building commenced behind home plate, and the baseball field was moved to the northwest area of just south of Paradise Creek (and Pullman Road) (). Aligned southeast and first used as "University Field" in it became Guy Wicks Field during the 1969 postseason. After fourteen seasons on the new field, baseball was discontinued as an intercollegiate sport at Idaho after the
