Bill Trenbeath Field at Roy S. "Spec" Keene Stadium is a quality small-college baseball facility, originally built in 1989. The stadium complex includes chairback seating in a portion of the grandstand, dugouts, and bullpens. The 2026 improvement project built a new paved ADA spectator area, berm seating, state-of-the-art lighting, and refurbished, newly-turfed fields and a bioswale that defies the rainy Oregon playing season.
