Herrerias succeeded Newell as Cal's head coach in 1960. He resigned in 1968 because of a dispute with an African-American athlete Bob Presley. Presley was suspended from the team for violation of team training rules. Presley was reinstated three days later, but relations between African-American and white players on the team remained tense. Herrerias resigned after the season. Herrerias has a record of 92-100 in his eight seasons at Cal.
