# Blue–Green rivalry

The Blue–Green Rivalry is the name of the rivalry between athletic teams from the University of California, Santa Barbara (Gauchos) and California Polytechnic State University, San Luis Obispo (Mustangs). Athletic competition between the two schools began in the 1921 on the football field.
The rivalry is best known recently for its games between the UC Santa Barbara Gauchos men's soccer and Cal Poly Mustangs men's soccer teams and is called the "Greatest Rivalry In College Soccer".

## History
### First meeting

The UCSB Gauchos and Cal Poly Mustangs met in their first collegiate athletic event on November 5, 1921. Santa Barbara State Teachers College, as UC Santa Barbara was known then, started a football team and played Cal Poly, with Poly coming out as 42–0 winners.

### California Collegiate Athletic Association

The rivalry heated up when both schools were members of the California Collegiate Athletic Association. The Gauchos joined the CCAA in 1939 and the Mustangs joined in 1945. The two would remain in-conference rival until the Gauchos departed in 1969 for the newly formed Pacific Coast Athletic Association.

### Big West Conference

The Pacific Coast Athletic Association would later become known as the Big West Conference. Cal Poly joined in 1996 and the two have been competing in-conference match ups since.

### Formalization of the Blue–Green Rivalry

The two schools announced the formalization of the Blue–Green Rivalry in 2009 to highlight the athletic accomplishments, but also to promote environmental sustainability. October 2012 saw the schools increase promotions of the rivalry, including the addition of a new website. However, this website has since been discontinued.

## Men's soccer

The best known of the Blue–Green Rivalry games, Cal Poly and UCSB play each other twice a year in Big West Conference play. With both schools located on the Central Coast of California less than 100 miles apart, attendance has risen dramatically following the Gauchos' 2006 NCAA Division I Men's Soccer Championship. The crowds of these games are record-setting and are among the highest regular season games in NCAA college soccer history.
