Alex Rodriguez will be suspended from Major League Baseball for the entirety of the 2014 season, the league announced Saturday.
In a statement, the league said arbitrator Fredric Horowitz ruled that Rodriguez's suspension includes the 162-game regular season and the entire postseason.
The New York Yankees third baseman, a three-time AL MVP, was suspended for 211 games on Aug. 5 by baseball Commissioner Bud Selig. The penalty was given for alleged violations of the sport's drug agreement and labor contract and followed Major League Baseball's investigation of the Biogenesis of America anti-aging clinic, which was accused of distributing banned performance-enhancing drugs.
Horowitz, MLB's independent arbitrator, heard the case over 12 sessions from Sept. 30 until Nov. 20. The sides submitted briefs last month.
Rodriguez's lawyers have threatened to go to federal court in an attempt to overturn a decision not to their liking. The Supreme Court has given judges little leeway to alter arbitrator's rulings.
