Josh Hamilton won't be disciplined by Major League Baseball for violating program

NEW YORK, N.Y. - An arbitrator has ruled Los Angeles Angels outfielder Josh Hamilton will not be disciplined by Major League Baseball for violating his treatment program.MLB said Friday it disagreed with the decision.Hamilton, the 2010 AL MVP, is subject to the treatment program for prior violations involving drugs of abuse.He self-reported a new violation this year involving both a drug of abuse and alcohol, a person familiar with the case said. The person spoke to The Associated Press on condition of anonymity because those details were not made public.A four-person treatment board created by baseball's joint drug program, which includes one lawyer and one medical representative each appointed by management and the players' association, deadlocked 2-2 on whether Hamilton should be disciplined. That caused the need for an arbitrator to break the tie.
