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.

Twins' Santana banned

Minnesota Twins pitcher Ervin Santana has been suspended for 80 games by after testing positive for the performance-enhancing substance Stanozolol.

This is the third penalty for a positive Stanozolol test reported by MLB in the last eight days, following Seattle pitcher David Rollins and Atlanta pitcher Arodys Vizcaino.

Santana must sit out the first half of the season. This is his first season with the Twins after signing a four-year, $55 million contract. He'll lose $5,901,639 of his $13.5 million salary this season.

Santana said in a statement released by the players' union he "can't pinpoint" how the substance entered his body.

Braves trade for Cahill

The Atlanta Braves acquired pitcher Trevor Cahill from Arizona, hoping to boost a staff that's been hurt by injuries.

The Diamondbacks sent Cahill for minor-league outfielder Josh Elander and agreed to send Atlanta $6.8 million to cover the majority of Cahill's $12 million salary this year.

The 27-year-old right-hander, an all-star with Oakland in 2010, was 3-12 with a 5.61 ERA for Arizona last season. He is 64-69 with a 4.07 ERA in six seasons.

Cosart fined for bets

Miami Marlins pitcher Jarred Cosart was fined by for placing illegal bets, but Major League Baseball said it found no evidence he bet on baseball.

The 24-year-old deleted his Twitter account last week after screen shots of comments he purportedly made appeared on the website of Miami New Times.

The amount of the fine and the details of the rules violation were not announced.

Tomlin to have surgery

Indians minor-league pitcher Josh Tomlin will have surgery on his right shoulder next week to treat joint inflammation.

Team officials said Friday that the 30-year-old, sent to the minors this week, will miss three to four months.

Bochy, Sabean extended

The San Francisco Giants extended the contracts of manager Bruce Bochy and baseball operations leader Brian Sabean through the 2019 season.

The Giants also announced Friday that Sabean, the longest-tenured general manager in the majors, had been promoted to executive vice president of baseball operations.
