FORT MYERS, Fla. (AP) — Minnesota Twins pitcher Ervin Santana has been suspended for 80 games by Major League Baseball after testing positive for the performance-enhancing substance Stanozolol.

MLB announced the punishment Friday. 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.
