The mother of Yankees pitcher Joba Chamberlain faces up to 20 years in prison on a felony drug-sale charge.

Jackie Standley pleaded no contest Monday to delivery of a controlled substance, according to the Lincoln Journal Star.

Standley, 44, was arrested in May after selling a gram of methamphetamine to an undercover officer at her Lincoln apartment.
