Ryan Braun has tested positive for a performance-enhancing drug and faces a 50-game suspension if the initial finding is upheld. Major League Baseball has not announced the positive test because Braun is disputing the result through arbitration. A spokesman for Braun issued a statement Saturday: "There are highly unusual circumstances surrounding this case which will support Ryan's complete innocence and demonstrate there was absolutely no intentional violation of the program. While Ryan has impeccable character and no previous history, unfortunately, because of the process we have to maintain confidentiality and are not able to discuss it any further, but we are confident he will ultimately be exonerated."
