Royals recall 4 to help depth in stretch run
Colon was in the starting lineup at third base for Tuesday night's game against Texas.
Gore gives the Royals a speedy threat on the base paths. He opened the season at Class-A Wilmington and climbed to Triple-A Omaha before spending time in Arkansas prior to his arrival.
Colon can play several infield positions, while Crow is a former All-Star reliever. Hendriks was impressive in a spot start last week, but will be used out of the bullpen down the stretch.
