Arbitrator who will hear Grievance in bounty case gets fired by the MLB

The reason for the rule is obvious: the tech could tamper with the sample if it's not shipped immediately.

Thus the tamper proof seals that were used. So, no matter how long it was held before shipping it wouldn't have made tampering any easier. If you were going to tamper with something that is seemingly tamper proof, wouldn't holding it over the weekend make it even more obvious? Braun was extremely lucky, but even the arbitrator knew he was guilty.
