Alex Rodriguez has filed a lawsuit against Major League Baseball and the MLBPA as he continues to fight his performance-enhancing drug-related suspension.

Rodriguez, who was suspended for the full 162-game season, claims alleging arbitrator Fredric Horowitz was biased in his ruling.

The lawsuit seeks to vacate Horowitz's ruling, based on the arbitrator's "manifest disregard for the law,'' his "evident partiality,'' and refusal "to entertain evidence that was pertinent and material to the outcome."
