DENVER (AP) - Jonathan Sanchez limited Colorado to three hits over six innings and the surging San Francisco Giants beat the Rockies 10-0 on Tuesday night.
After five straight no-decisions, Sanchez (8-6) won for the first time since July 5 and equaled his 2009 victory total. Sanchez struck out seven straight batters at one point and finished with nine strikeouts before leaving after a leadoff walk in the seventh.
The Giants, who have won four straight games and 21 of their past 26, had a four-run first inning against Aaron Cook (4-8), who lasted three innings and allowed eight hits and five runs. In his past three starts, Cook is 0-3 with a 13.97 ERA.
The Giants chipped away at Cook for four runs in a 36-pitch first inning. After Cook issued a one-out walk, putting runners at first and second with one out, consecutive singles by Buster Posey, Pat Burrell, Travis Ishikawa and Pablo Sandoval resulted in four runs. Sanchez added a fifth single, but left fielder Ryan Spilborghs threw out Ishikawa at the plate to end the inning.
Cook retired the side in order on seven pitches in the second but gave up a one-out homer to Burrell in the third. Burrell is 15 for 24 (.625) against Cook with one double, two homers and seven RBIs, which is the highest average by any player, active or retired, with a minimum of 20 plate appearances against Cook.
The Giants matched their season-high with 19 hits, the most allowed by the Rockies this season.
Taylor Buchholz relieved Cook and gave up a run-scoring single to Posey in the fifth and a solo homer to Freddy Sanchez in the sixth. Posey, who is hitting .356 since being recalled May 29, went 3 for 5. He and Burrell each had two RBIs.
After Jonathan Sanchez left, Javy Lopez walked the bases loaded, but second baseman Sanchez made a leaping catch of Carlos Gonzalez's line drive to end the seventh.
Pinch-hitter Juan Uribe had an RBI single and Andres Torres hit a two-run homer off Manuel Corpas in the ninth.
The Rockies, whose four-game winning streak ended, were shut out for the fourth time this season and second time at home. It was the most-lopsided home loss of the season.
The Rockies were held to three hits, matching their season-low. In addition to singles by Todd Helton, who was activated Tuesday and played his first game for the Rockies since July 4, and Buchholz, Melvin Mora doubled in the sixth.
