Third baseman Alex Gordon, designated hitter Billy Butler and shortstop Tony Pena Jr. each are in their second year as Kansas City favorites.
Also on the ballot are three position players with more seniority -- outfielder Jose Guillen, second baseman Mark Grudzielanek and first baseman Ross Gload.

Among the Royals only pitcher Gil Meche, selected as the Royals representative last year, and Grudzielanek, picked in 1996 as a shortstop with the Montreal Expos, have appeared in an All-Star Game.
The last Royals player to be voted onto the starting lineup was outfielder Jermaine Dye in 2000 at Atlanta.

Through last weekend, Guillen and Gordon each had 10 RBIs and Gload had a .300 average.
