Retired Stanford University Water Polo coach Dante Dettamanti, 80, was killed while riding his bike on Cañada Road in San Mateo County on Tuesday, friends of Dettamani told this news organization.

At around 4:05 p.m. on Tuesday, the California Highway Patrol received a call that a man had crashed into a San Mateo County Public Works Department street sweeper parked on the right shoulder of the road about a half mile south of state Route 92, said Art Montiel, a spokesperson for the Redwood City CHP area.

Dettamani's decadeslong coaching career at Stanford began in 1976. He helped the team bring home eight NCAA championships and was named NCAA Coach of the Year five times, according to USA Water Polo.

Dettamanti, who swam and played water polo as a student at University of California, Davis, was elected to the USA Water Polo Hall of Fame in 2002.

Upon retiring, Dettamanti became involved in winemaking in the Santa Cruz Mountains, according to an interview with Stanford.
