NEW YORK - Alex Rodriguez is taking Major League Baseball to federal court in hopes of overturning a season-long suspension.

The embattled Yankees third basemen filed a lawsuit Monday against the MLB and its players' union in response to a suspension that stemmed from the league's drug investigation.

Over the weekend, an arbitrator had reduced A-Rod's penalty from 211 missed games to 162, plus any postseason games. The arbitrator said there was "clear and convincing evidence" that the three-time MVP had used three banned substances and tried to obstruct the MLB's biogenesis investigation.

The lawsuit comes on the heels of a "60 Minutes" interview that aired on CBS Sunday where Anthony Bosch claimed that Rodriguez frequented his secret doping clinic in Florida.
