Controversy
In July 2021, the entire UC Davis Aggies baseball program was suspended and the coaching staff was placed on administrative leave due to allegations of misconduct. An internal investigation found that players engaged in hazing rituals that included binge drinking, eating live goldfish, strippers, and threats of sexual assault. The team was allowed to resume some activities in October under the supervision of an interim coaching staff. Manager Matt Vaughn resigned in November after the administration found he had failed to address concerns regarding a complaint about hazing from 2018.
