In an attempt to overturn the suspension that precludes Alex Rodriguez from playing in 2014, the slugger's representatives on Monday as expected sued Major League Baseball and the MLB Players Association, alleging the ban was handed down without just cause.
The lawsuit, filed in U.S. District Court in New York City, also alleges that the Players Association breached its "duty of fair representation," according to court documents cited by The Associated Press.
The filing follows arbitrator Frederic Horowitz upholding most of MLB's suspension of Rodriguez that was issued last August. Horowitz kept in place 162 games of Rodriguez's original 211-game ban, wiping out the 2014 season for the slugging third baseman.
According to the lawsuit, Horowitz found "clear and convincing evidence" that Rodriguez used three banned substances and twice tried to obstruct the sport's drug investigation, the AP reported.
Horowitz's ruling was released only after U.S. District Judge William H. Pauley III denied a motion by Rodriguez's lawyers to file the lawsuit with the arbitrator's ruling redacted to protect the confidentiality of the arbitration process.
Rodriguez was suspended last August games for his role in the Biogenesis PED affair. The lawsuit filing also comes after MLB's chief witness in Rodriguez's arbitration hearing, Anthony Bosch, told "60 Minutes" on Sunday that he personally injected Rodriguez with performance-enhancing drugs.
