The fleet-footed Gordon won the National League batting title by hitting .333 last season and signed a $50 million, 5-year deal with Miami in January. He's made two All-Star teams in his six seasons and won the Gold Glove and Silver Slugger awards at second base last year.

Gordon had a key hit in Miami's win over the Dodgers on Thursday. He's batting .266 with six stolen bases this season.
