REDWOOD CITY, Calif. (AP) — The 20-year-old son of former San Francisco Giants slugger Barry Bonds has pleaded no contest to misdemeanor vandalism and assault charges stemming from a fight with his mother.

Nikolai Bonds entered the plea Thursday as part of a deal with San Mateo County prosecutors. Three additional misdemeanor charges were dropped.

Chief Deputy District Attorney Steve Wagstaffe says Bonds was sentenced to four days in jail but given credit for time served.

Authorities say Bonds threw a doorknob at his mother, Sun Bonds, spit in her face and stopped her from leaving through the front door of her Menlo Park home on Dec. 5 after she suggested his friends may have taken jewelry.

Wagstaffe says prosecutors reached a deal because Sun Bonds refused to cooperate in the case.
