Joba Chamberlain's Mom -- Alleged Meth Dealer

The mother of New York Yankee pitcher Joba Chamberlain has been arrested for allegedly slinging hardcore drugs to an undercover cop.

Jacqueline Standley was popped at her Lincoln, Neb. apartment on Saturday night after allegedly selling ".6 gram of methamphetamine in a plastic bag" to a cop for $110 back in February.

Once toxicology reports came back from the lab, Standley was arrested and charged with delivery of an exceptionally hazardous drug -- a felony -- and bond was set at $5000.

Just last month Joba was sentenced to nine months probation after pleading guilty to DUI.

Like mother, like son.
