Less than three months after Major League Baseball objected to the overturning of Ryan Braun’s 50-game suspension for a positive drug test, Shyam Das, the arbitrator in that case, was fired, according to a person in baseball with direct knowledge of the decision.

Braun became the first major league baseball player known to have won an appeal of a drug suspension when he convinced Das that his urine samples taken in early October were mishandled by a drug collector. The collector waited two days before shipping them to a testing laboratory, rather than on the day they were collected, allowing Braun to question whether they were tampered with.

Rob Manfred, the executive vice president for Major League Baseball, vehemently disagreed with the decision and defended the league’s collector in the case after Braun raised questions about his integrity.
