San Francisco, CA -- (Sports Network) - Tim Lincecum fired seven innings of three-hit shutout ball, and the Giants bats produced a second straight solid effort in a 9-0 win against the Astros.

Lincecum (9-2), fresh off being named the NL's Pitcher of the Month for June, won for the fifth time in his last six starts and for the ninth time in his last 10 decisions.

The reigning Cy Young Award winner for the Senior Circuit struck out nine, walked two and walked twice himself, scoring both times. He has now allowed two runs or less in eight of his last nine outings and has fanned at least eight batters in each of his last five starts.

"He is one of the best. Those elite players get on a roll and it's impressive. He is commanding all his pitches. It's enjoyable to watch," Giants manager Bruce Bochy said.

San Francisco pounded out the nine runs on 12 hits one day after taking the opener to this three-game set in similar fashion, 13-0. Aaron Rowand and Randy Winn had a pair of RBI each, while Pablo Sandoval reached base four times with two hits and two walks, driving in a run in the win.

Former Giants right-hander Russ Ortiz (3-4) was tagged for nine hits and eight runs with five walks in a 5 2/3-inning start. Houston had entered the series winners in six of its previous eight but have managed just seven hits in the first two games versus the Giants.

The game was actually scoreless after 4 1/2 frames but the Giants scored twice in the fifth and broke it open with a six-run sixth. Sandoval knocked in Lincecum with a single to right to open the scoring, and Winn scored on a passed ball to close the fifth.

Lincecum walked for a second consecutive inning to load the bases with two outs in the sixth, and the Giants went on to rally for six runs. Rowand drove in two with a base hit to left and Winn doubled to right-center to plate two more. After Sandoval was intentionally walked, Chris Sampson came on but Bengie Molina greeted him with an RBI double and Nate Schierholtz followed with a run-scoring single to center.

"Russ threw the ball fine. He just ran out of gas there in the sixth," Astros manager Cecil Cooper said. "Unfortunately when we walked the pitcher twice it came back to hurt us. Maybe I should have pulled the string a little earlier than I did but that's a little thing. We had some chances there, but their guy threw pretty good. That's what good pitching can do."

Rich Aurilia added a sacrifice fly in the eighth to account for the final margin.
