Home to Cal Poly Softball, Bob Janssen Field is the beautiful sister facility to Baggett Stadium. Named in honor of area patron and sports enthusiast Bob Janssen, the stadium is located on the north side of the campus and faces southwest toward the Pacific Ocean and famed Bishop’s Peak. Known as a pitcher's ballpark, sun drenched fans and players alike quickly learn that the occasional breezes off the Pacific Ocean can stop a potential home run shot in its tracks or wreak havoc with casual fly balls.
Sharing a common plaza entrance with Baggett Stadium, Bob Janssen Field is beautifully landscaped and maintained as a wonderfully comfortable venue with its 400 chairback seats, seating capacity for 800, tower lighting for night games, as well as a spacious home clubhouse along with batting cages and bullpen areas for home and away teams.
