Gordon, a two-time All-Star, led the NL in hits (205), stolen bases (58) and batting average (.333). He signed a five-year, $50 million contract extension with the Marlins last year.
His suspension was announced moments after the Marlins completed a four-game sweep of the Dodgers in Los Angeles. The Marlins acquired him from the Dodgers in a six-player trade in December 2014.
Gordon will sacrifice about half of his $3 million salary in 2016 and won’t be able to defend his titles
