Rockies starter Jhoulys Chacin (11-6) set an effective tone from the outset, working out of first-inning trouble by inducing Yonder Alonso to ground into a double play with runners at first and third and one out. Corey Dickerson then made a tremendous running catch of Decker's drive to left, and Dexter Fowler tracked down Nick Hundley's fast-moving fly to center at the warning track. Colorado got to Volquez early, going in front in the first inning on Wilin Rosario's two-run single. Dickerson went to third on a wild pitch and scored Colorado's fifth run on a grounder by Tulowitzki, who reached on third baseman Chase Headley's errant throw to first. After the Rockies came off the rain delay to score six runs in the eighth, helped by the Padres' fourth error of the game on a dropped throw by first baseman Alonso, Gyorko connected off Jeff Francis for his 11th homer. Padres OF Kyle Blanks, on the 15-day disabled list since mid-July with a left Achilles' injury, is set to begin running again later this week. Padres LHP Eric Stults (8-10) is slated to pitch the second game of the set against Jeff Manship (0-1), who was recalled a week ago from the club's Triple-A affiliate in Colorado Springs.
