Rob Manfred, MLB's executive vice president of labor relations, also gave MLB's first explanation for last week's decision to fire Shyam Das, the arbitrator who in February overturned a 50-game suspension for NL MVP Ryan Braun following a positive drug test. Braun's lawyers argued his urine sample wasn't handled as specified in baseball's drug agreement.
"Shyam served for 13 years. That's a very long time," Manfred said. "He's a very high-quality arbitrator. We made a decision to exercise our contractual right to make a change. There's nothing more to that."
Management and the union are to talk next week about selecting a new arbitrator, who would hear the union's grievance to overturn a 100-game suspension for Giants reliever Guillermo Mota.
Mark Walter and Stan Kasten, the Dodgers' new chairman and president, attended their first owners' meeting since buying the team from Frank McCourt on May 1 in a record $2 billion deal. Owners approved a six-year extension of the major league constitution and Baseball Advanced Media, the sport's Internet division.
