SAN FRANCISCO — For most of his outing, Barry Zito had a large lead that would make most pitchers plenty comfortable.
Zito never allows himself to think that way. Not with all the ups and downs of his Giants tenure.
"I think the mindset that it's easier because you have a lead will tie the game up quickly," he said.
Buster Posey drove in three runs, Zito pitched another gem and contributed with his bat, and the San Francisco Giants beat the Colorado Rockies 10-0 on Wednesday to complete a three-game sweep.
Staked to a quick lead, Zito (2-0) won his 11th straight decision, including last year's postseason. San Francisco earned its 16th consecutive victory in games he has started.
