DENVER (AP) - Aaron Cook pitched seven sharp innings to win his seventh straight decision and Seth Smith scored two runs, leading the Colorado Rockies to a 4-2 win over the San Francisco Giants on Sunday.
Cook (10-3) had his trademark sinker working all afternoon, getting the Giants to hit into 16 groundouts. He allowed nine hits and struck out two for his seventh winning decision.
Franklin Morales pitched a perfect eighth and Huston Street retired the Giants in order in the ninth for his 25th save in 26 chances.
By taking two of three in the series, the Rockies increased their NL wild-card lead to two games over the Giants.
San Francisco pitched cautiously to Troy Tulowitzki on Sunday after he drove in a career-high five RBIs the night before.
