George Brett will be back on the field on July 8 at Kauffman Stadium, where he racked up most of his 3,154 hits for the Royals in a 21-year career. But he has a lot of company. Jon Hamm of "Mad Men," David Cook and Haley Reinhart of "American Idol" fame, and past greats Ernie Banks, Andre Dawson, Rollie Fingers, Rickey Henderson, Ozzie Smith, Dave Winfield, Joe Carter, Mike Piazza, Bo Jackson and Mike Sweeney also will play in the 2012 Taco Bell All-Star Legends & Celebrity Softball Game.
