[3][4] The stadium originally had a usual, day-to-day capacity of 1,734[5] before later expansion, and is part of an encompassing 47-acre (190,000 m2) Upper Sports Complex which is also home to the Mustang softball team.

In a matter of minutes after going on sale, Cal Poly quickly sold out its first game of the regional against Sacramento State.

[15] The previously existing clubhouse, which had stood for 17 years,[16] was demolished on June 11, 2018 by the project's contractor, Exbon Development of Garden Grove, California.

In addition, new permanent seating and backstop safety netting[17] was installed by the start of the 2018 season, raising the capacity to 3,138.

In 2022, Cal Poly ranked 38th in the nation in average home attendance, drawing 1,905 fans per game to Baggett Stadium.
