Alex G. Spanos Stadium

California stadium

Mustang Memorial Field, formerly known as Mustang Stadium and then Alex G. Spanos Stadium, is an 11,075 seat multi purpose stadium located on the campus of California Polytechnic State University (Cal Poly) in San Luis Obispo, California. It is the home field of the Cal Poly Mustangs football and soccer teams. The stadium was renovated largely from funding from alumnus Alex Spanos (1923–2018), an American billionaire real estate developer, founder of the A. G. Spanos Companies, and majority owner of the San Diego Chargers of the National Football League (NFL).

Originally opened in 1935, the stadium was expanded in 2006 to its current capacity and, following the completion of a $21.5 million renovation, was then renamed Alex G. Spanos Stadium in a pregame ceremony on November 18. The recognition and subsequent renaming for the ensuing 15 years was the result of an $8 million donation to renovate Mustang Stadium by Alex Spanos, the largest single donation in the school's history at the time. At the next season's home opener following the dedication, Cal Poly debuted a tailgating section perpendicular to the stadium's entrance along South Perimeter Road, and set a sellout record of 11,075 fans as the Mustang football team defeated Weber State. Previous expansions to the stadium's steel east side grandstands were completed in 1972 and 1979. Artist renderings of further increasing the stadium's capacity to 25,000 were released in 2010. In 2013, Cal Poly replaced the south end zone rented stands with permanent aluminum stands improving handicapped access. Additionally, Cal Poly renovated the lower portion of the older east side bleachers to add handicapped seats and improve accessibility and egress. The new south endzone stands increased capacity by 345 seats. The playing field is aligned north northwest to south southeast at an approximate elevation of 300 feet (91 m) above sea level. Formerly natural grass, FieldTurf was installed in 2022. In November 2022, the university announced the facility would be renamed Mustang Memorial Field Presented by Dignity Health French Hospital Medical Center, reflecting a new 10 year naming rights agreement between the college and the healthcare organization. The first official events to be held at the facility under the new name were the semifinals and championship match of the 2022 Big West Women's Soccer Tournament.

From August 4–14, , the Baltimore Colts, featuring Johnny Unitas, Bubba Smith, and head coach Don Shula, spent nearly two weeks holding a preseason training camp in the stadium, with practice and scrimmages open to the public. The Colts played the San Diego Chargers in a preseason game on August 2, before heading north to visit the Oakland Raiders on August 9, in between their stay in San Luis Obispo.

Cal Poly Mustangs football, as well as the men's and women's soccer teams, play their home games at the stadium. Meanwhile, in 2023, the city's Mission College Prep Royals began playing Friday night football games in the stadium.
