The Players Choice Awards, made by the Major League Baseball Players Association, honor a player of the year and man of the year, encompassing both leagues, plus an outstanding player, pitcher, rookie and comeback player in each league. Hosmer was the only Royals player nominated.
The awards will be announced on MLB Network from 7 to 8 p.m. CT on Thursday, Nov. 3.
Players Choice Awards have been presented annually since 1992 when Major Leaguers selected Dennis Eckersley and Barry Bonds as the AL and NL Outstanding Players, respectively. Balloting for the 2011 Players Choice Awards was conducted in mid-September under the supervision of accounting firm KPMG.
The 2011 Players Choice Award winners in all categories will designate charities to receive grants totaling $260,000 from the Major League Baseball Players Trust, the charitable foundation created and run by the players themselves.
The Players Trust raises funds and attention for issues affecting the needy and promotes community involvement. Since 1992, the Players Trust has recognized the outstanding on-field and off-field performances of Players Choice Awards winners by contributing more than $3 million to charities around the world.

The 2011 Players Choice Awards Presented by 2K Sports will be hosted by MLB Network's Matt Vasgersian and Harold Reynolds.
