Each team submits one nominee for the award, which is given to the winners during the World Series. Hank Aaron personally selects each winner, with Tony Gwynn, Paul Molitor, Joe Morgan and Robin Yount lending their opinions and expertise, as well.
Butler is facing stiff competition, with Josh Hamilton (Texas), Derek Jeter (New York), Miguel Cabrera (Detroit) and Edwin Encarnacion (Toronto) also being nominated. Jeter is the only player nominated this year who has previously won the award, while Ryan Braun, Andrew McCutchen, Giancarlo Stanton and Cabrera are the only players who were nominated last season as well as in 2012.
