The stadium opened on January 21, 2001, with the Mustangs defeating #1 ranked Stanford 6–5 in 12 innings. The stadium has a capacity of 1,734 and is part of a facility which is also home to the Mustangs softball team. The stadium can be expanded with additional bleachers to a capacity of 3,042 as was the case for the 2014 NCAA Baseball Regional hosted by Cal Poly. The record attendance for a 3-game series is 8,585 vs Cal State Fullerton May 6–8, 2005. In 2012, college baseball writer Eric Sorenson ranked the field as the fifth best setting in Division I baseball. In 2013, the Mustangs ranked 51st among Division I baseball programs in attendance, averaging 1,290 per home game. In 2014, the Mustangs ranked 40th among Division I baseball programs in attendance, averaging 1,505 per home game. In 2014 Cal Poly hosted its first ever Division 1 Baseball Tournament Regional. The regional featured Cal Poly as the #1 seed along with Arizona State, Pepperdine and Sacramento State. In a matter of minutes after going on sale, Cal Poly quickly sold out its first game of the regional against Sacramento State. Actual Attendance peaked Saturday night at 2,941 with Cal Poly's 2nd game despite all 3,042 tickets being sold out. In 2018 the university began a $8 million enhancement project at Baggett Stadium. The project includes a two-story, 10,000-square-foot clubhouse complete with a lounge and kitchen, meeting and study space, locker room, training room, offices, and a therapeutic cold plunge pool. In addition, new seating and backstop safety netting was installed by the start of the 2018 season, raising the capacity to 3,138. Announced February 13, 2019, a new Daktronics videoboard ranging 36 feet to 20.4 feet was added, with 1,080-by-612 pixel resolution LED lighting. As part of an almost overall $10 million project, an $8 million Dignity Health Baseball Clubhouse is nearing completion. The two-story, 10,000-square-foot clubhouse is planned to include a lounge and kitchen, meeting and study space, locker room, offices and a therapeutic cold-plunge pool. The previously existing clubhouse, which had stood for 17 years, was demolished on June 11, 2018 by the project's contractor, Exbon Development of Garden Grove, California. Permanent bleachers providing increased seating capacity to 3,238 fans were added along with new backstop safety netting before the 2018 season. Before the clubhouse project, a 6,000-square-foot lighted hitting area was completed for roughly $300,000 in November 2012, with retractable netting allowing for three long cages alongside three short cages.
