Kyle Harrison pitched seven scoreless innings and the San Francisco Giants scored four runs in a decisive fourth inning despite getting only two balls out of the infield in a 5-0 victory over Colorado on Tuesday. Harrison (3-1) gave up four hits, all singles, and struck out two. The Giants, who snapped a four-game skid, ended an 11-game streak of scoring no more than four runs in one game, a day after manager Bob Melvin held a post-game meeting following a 6-1 loss at Philadelphia.
