The lab chief, an MLB source told Munson, testified that the urine was not tainted, that it was appropriate for testing, and that it tested positive for testosterone. The baseball officials, sources said, were incensed that Braun, his attorneys and the union successfully attacked the integrity of a collection procedure that is a "joint" procedure.
The word "joint" in this context means that the union and the league agreed to the procedure, made a mutual decision to hire the collection agency and were both obligated to abide by the results. Any failure to follow the joint procedure, the league officials assert, is a "technicality" and had no effect on the integrity of the sample or the results of the test.
"Our program is not fatally flawed," MLB executive vice president Rob Manfred said in a statement. "Changes will be made promptly to clarify the instructions provided to collectors regarding when samples should be delivered to FedEx based on the arbitrator's decision. Neither Mr. Braun nor the MLBPA contended in the grievance that his sample had been tampered with or produced any evidence of tampering."
In his appeal, Braun didn't argue evidence of tampering and didn't dispute the science, but argued protocol had not been followed
. Multiple sources confirmed to ESPN investigative reporters Mark Fainaru-Wada and T.J. Quinn that Braun questioned the chain of custody and collection procedure.
MLB officials argued that there was no question about the chain of custody or the integrity of the sample, and that Braun's representatives did not argue that the test itself was faulty.
But multiple sources said the sample was not shipped for testing as soon as possible, as required by the drug testing policy, and instead was kept in a cool place in the sample collector's home. Sources told Munson that the collector put Braun's sample on a desk in a Tupperware container and left it there for two days.
Sources also told Munson that there was doubt over whose urine was actually being tested. Braun offered to take a DNA test to confirm whose urine was in the sample, but Major League Baseball declined. However, an MLB source told ESPN's Mike Golic that Braun's side backed off of the offer to take a DNA test.
