While it is unclear if MLB ever did get clean(I know Bud, I know), it now appears several recent tests from Ryan Braun to the latest for Yasmani Grandal might be demonstrating the extent of "clean" depends on the type and sensitivity of the test contrasted with the the evolution of the drugs.
Tom Verducci does some good writing(although I didn't like his SI coverage of the WS all that much) and this coverage sends a message which is troubling.
