NEW YORK (AP) ― National League MVP Ryan Braun’s 50-game suspension was overturned Thursday by baseball arbitrator Shyam Das, the first time a baseball player successfully challenged a drug-related penalty in a grievance.

The decision was announced Thursday by the Major League Baseball Players Association, one day before the 28-year-old outfielder was due to report to spring training with the Milwaukee Brewers. The commissioner’s office and the U.S. Anti-Doping Agency each were disappointed and angry about the ruling.

Braun’s urine tested positive in October for elevated testosterone, and ESPN revealed the positive test in December.

Braun has insisted that he did not violate baseball’s drug agreement.

“I am very pleased and relieved by today’s decision,” he said in a statement. “It is the first step in restoring my good name and reputation.”
