Former Blue Jays pitcher and top draft pick Matt Bush has pleaded not guilty to drunken driving, resisting arrest and vandalism for an incident last month in which he backed into a parked car in Mission Valley, Calif.

A lawyer entered pleas for Bush on Wednesday in a San Diego County courtroom. Lawyer Gregory Daniels said the 23-year-old pitcher, who's had several alcohol-related incidents, is in rehab.

The San Diego Padres drafted Bush with the first pick in 2004 and traded him to Toronto in February after he allegedly assaulted members of a high school lacrosse team. He's charged with misdemeanour battery in that case.

The Blue Jays released Bush in April for failing to comply with team guidelines.
