Once Tim Lincecum left with a knee injury, the Astros had their way with the Giants' pitching staff.

Lance Berkman hit a grand slam in an eight-run seventh, two innings after Lincecum left the game with a bruised right knee, and the Astros beat the Giants 12-4 on Tuesday night for their sixth straight victory, as reported by the Associated Press.
