According to multiple reports, La Russa will serve six months probation and perform 50 hours of community service, pay a fine and attend a DUI school. He was arrested March 22 in Jupiter, Fla., the Cardinals' Spring Training home, when he was found asleep at the wheel of his sport-utility vehicle.
"We addressed this matter with Tony last season and the nature of those discussions will remain private," said Cardinals principal owner Bill DeWitt Jr. in a statement issued by the team. "We have been satisfied with Tony's responsible approach to this issue and we respect his decision. With today's news, our ball club considers the matter closed."
The Associated Press and the St. Louis Post-Dispatch reported that La Russa's attorney, David Roth, issued a statement on behalf of the manager.
"I accept full responsibility for my conduct, and assure everyone that I have learned a very valuable lesson and that this will never occur again," the statement read.
Calls to Roth were not returned.
