Alex Rodriguez is suing both Major League Baseball and the players' union in an effort to overturn his season-long suspension.
In the complaint filed Monday, Rodriguez claims that the union "completely abdicated its responsibility to protect his rights."
An arbiter decided Saturday that the Yankees third baseman should be suspended for the entire 2014 season, which is actually less than the initial suspension of 211 games handed down by the league in August.
The three-time MVP denies taking illegal substances after 2003, but he has been accused of doping at a Miami anti-aging clinic.
His lawyer, Joseph Tacopina, had harsh words for the clinic's founder, Anthony Bosch, and the interview he gave to 60 Minutes.
"He's someone who's an admitted liar, someone who's an individual that has a motive and a bias to testify against Alex because he got something for that testimony," Tacopina said.
Rodriguez's attorney admitted that the injunction he's seeking is a long shot, but said that even if the suspension stands, A-Rod is planning to show up to spring training in Tampa, which he'd be allowed to do.
