according to mlb.com's story...
We actually know very little about the details at this moment. Game, set, and match? Right now the first set isn't even over.According to sources cited in the ESPN.com report, Braun submitted a urine test during the playoffs in October that showed a level of testosterone high enough to trigger a positive test. A second test on the sample revealed that the testosterone was exogenous, or from outside Braun's body, meaning it was generated by a synthetic substance.
FOX's Ken Rosenthal also offered a different account via Twitter on Sunday.
"What he did triggered violation of #MLB steroid-testing policy," Rosenthal wrote. "Source says substance was prohibited, but not PED."
