All three were at Minute Maid Park on Sunday for Game 3 of the American League Division Series -- Walker to sing the anthem, and the Bushes to assume ceremonial first pitch honors.
Sunday's pregame ceremony took place with most of the sellout crowd, wearing orange and clapping their Hustle Town Thunderstixx, already assembled in their seats.
As Walker sang the anthem, 75 season-ticket holders unfurled a large American flag in the outfield. The pregame ceremony concluded with the Bushes throwing the first pitch to infielder Jed Lowrie.
