Alex Rodriguez's lawsuit claiming Major League Baseball and Commissioner Bud Selig went on a "witch hunt" to force him from the sport has been moved from state to federal court.
Major League Baseball filed a notice of removal Monday, saying claims by the New York Yankees third baseman are governed by federal law.
The lawsuit, originally filed Thursday in New York Supreme Court in Manhattan, was assigned to U.S. District Judge Lorna G. Schofield, who joined the bench in December, and U.S. Magistrate Judge Kevin N. Fox.
Rodriguez's legal team could file a motion asking that the case be returned to state court. One of his lawyers, Joseph Tacopina, said in a statement that the league "knows that these state law claims properly belong where they were filed, in the New York state court."
The legal action comes during a grievance by the Major League Baseball Players Association to overturn a 211-game suspension given to Rodriguez by MLB on Aug. 5 for alleged violations of baseball's drug agreement and labour contract.
A hearing began last week before arbitrator Fredric Horowitz. After a week of sessions, three additional days are scheduled starting Oct. 15, and more days may be needed. A decision is unlikely before winter.
In his lawsuit, Rodriguez claimed MLB and Selig tried to smear the three-time AL MVP and cost him tens of millions of dollars in an attempt to cover up Selig's alleged past inaction on performance-enhancing drugs. The lawsuit claimed Selig hoped to redeem himself by going after Rodriguez.
MLB responded by calling Rodriguez's actions "desperate" and a violation of the confidentiality provisions of the league and union's Joint Drug Agreement.
On Friday, Rodriguez sued the Yankees team physician and a New York hospital in New York Supreme Court in the Bronx, claiming they mishandled his medical care during the 2012 American League playoffs by letting him play after failing to inform him that a test revealed an injury to his left hip joint.
The lawsuit said Rodriguez then further injured himself, forcing him to suffer hospitalization, disability and emotional distress.
During the 2012 post-season, Rodriguez hit .120 (3 for 25) with no RBIs before undergoing left hip surgery in January that prevented him from rejoining the Yankees until August.
