Youth served the Rockies quite well Tuesday night at frosty Coors Field. Left-hander Kyle Freeland, 24, pitched one of the best games of his budding career, tossing seven scoreless innings of three-hit ball. He struck out eight, walked just two and needed only 90 pitches to get the job done. Boxscore Shortstop Trevor Story, 25, blasted a grand slam in Colorado’s five-run second inning.
