The San Francisco Giants hope three games at hitter-friendly Coors Field will be a tonic for their stagnant offense as they eye October. The Colorado Rockies, their postseason hopes unrealistic at this point, will try to bounce back from a series loss against the Arizona Diamondbacks and end a homestand with a winning record when they begin a three-game series Monday with the Giants. The Giants are 7-6 against the Rockies this season, and the teams have split six games at Coors Field.
