In August, Yankees third baseman Alex Rodriguez's lawyers wrote a letter to the Major League Baseball Players Association requesting that it stop representing him, Serge F. Kovaleski and Steve Eder of the New York Times report. The letter, which the Times acquired only recently, shows Rodriguez as suspicious not only of Major League Baseball and the arbitration system, but also of the players' union, Kovaleski and Eder suggest.

The letter claims that the MLBPA did not "fairly represent [Rodriguez's] interests" in the Biogenesis investigation. Rodriguez's attorneys also claim that MLBPA executive director Michael Weiner did Rodriguez a disservice by suggesting in a radio interview that Rodriguez should have accepted a suspension.

The MLBPA has "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," according to the letter.

The MLBPA's David Prouty still participated in representing Rodriguez in arbitration hearings this month. Rodriguez continues to fight his 211-game suspension for his role in the Biogenesis scandal.
