Anthony Daniel Chaidez, 25, of Riverbank was convicted March 5 of assault likely to cause great bodily injury.
Judge Marie Silveira sentenced him to four years in state prison.
Chaidez admitted having served two years in prison in 2006 for a residential burglary, which falls under California's "three-strikes" law.
On Dec. 14, during an argument at a Riverbank residence, Chaidez pulled out an extendable baton weapon and swung it at the victim's head. Chaidez missed hitting the victim by inches.
Never miss a local story.
He then fled the scene and was found at his residence a couple of blocks away with the baton in his possession.
