DENVER (AP) -- Jason Hammel shook off a leadoff home run to pitch seven strong innings and Chris Iannetta backed him with a three-run homer Saturday night in the Colorado Rockies' 4-1 victory over the Pittsburgh Pirates.
Hammel (3-1) allowed six hits, including Andrew McCutchen's eighth career homer to start a game.
But Hammel kept the Pirates in check after that, striking out four and walking two. He also benefited from a Rockies defense that turned three double plays.
Rafael Betancourt pitched a scoreless eighth and Huston Street got the final three outs for his NL-leading 10th save in 10 chances.
