Carlos Gonzalez drove in the go-ahead run and the Colorado bullpen tossed five scoreless innings Saturday in the Rockies\' 4-3 win over the Chicago Cubs. With the game tied 3-3 in the seventh, pitcher Carlos Torres (3-1) led off with a single and was forced at second on DJ LeMahieu\'s groundout. LeMahieu went to second on a Jordan Pacheco single, which chased Cubs reliever Manny Corpas (0-1).
