Last year during Spring Training, arbitrator Shyam Das overturned Ryan Braun's 50-game suspension for PED usage. Braun's attorneys successfully argued for their client, alleging that the collection process of Braun's sample was flawed.
After the snafu with Braun left MLB with egg on their face, they changed their collection policy for the 2012 season and beyond. The New York Daily News has the details.
Now, the collectors use glass bottles, made by the same manufacturer, but considered even more secure. The bottles have a locking mechanism on the top, as opposed to tamper-proof stickers on the plastic version. The only way to open the glass bottles is to smash the top with a hammer, which the lab does in what a person familiar with the process described as a “controlled manner.”
That's right: glass bottles that need to be broken by the lab techs. I see no way this can go wrong at all. At least the plastic containers typically used in the past wouldn't shatter when dropped on the floor, which is something I can definitely see happening with these new glass containers.
