A day after Alex Rodriguez filed suit against Major League Baseball, commissioner Bud Selig and a Yankee team doctor, the New York Times’ Serge F. Kovaleski and Steve Eder report the embattled third baseman lashed out at the Players Union this past August, “formally requesting the union step aside from its prescribed role as his chief representative on his arbitration panel.”  Spare a thought for MLBPA’s executive director, Michael Weiner, who has the dubious pleasure of defending A-Rod while simultaneously battling brain cancer.

The letter, which was obtained by The New York Times and has not been previously reported, was dated Aug. 22 and sent on the letterhead of Reed Smith, one of the law firms representing Rodriguez. In it, Rodriguez’s lawyers notified the players association that they believed the union failed to “fairly represent his interests” regarding Major League Baseball’s investigation of Biogenesis of America, a South Florida anti-aging clinic that baseball officials say dispensed banned substances to ballplayers, including Rodriguez.

The letter argued that the players association had missed opportunities to challenge baseball officials’ aggressive investigative tactics; that the union had not strongly enough condemned baseball’s “gratuitous leaks” to the news media; and, most pointedly, that Michael Weiner, the union’s executive director, had publicly compromised Rodriguez’s position in a radio interview when he signaled that Rodriguez should have accepted some type of suspension “based on the evidence we saw.” Rodriguez and his personal lawyers have steadfastly maintained that Rodriguez should not have been suspended.

The union “has made matters worse by failing to protest M.L.B.’s thuggish tactics in its investigation, including paying individuals to produce documents and to testify on M.L.B.’s behalf, and bullying and intimidating those individuals who refuse to cooperate with their ‘witch hunt’ against the players — indeed principally Mr. Rodriguez,” the letter said.
