SAN FRANCISCO (AP) Tommy Kahnle and four relievers combined for two-hit ball over six innings after Brett Anderson was injured, leading the Colorado Rockies to a 1-0 victory over Matt Cain and the San Francisco Giants on Saturday.
Troy Tulowitzki had a sacrifice fly in the third inning for Colorado. Kahnle (2-0) allowed one baserunner in two innings. Matt Belisle, Adam Ottavino, Rex Brothers and LaTroy Hawkins pitched an inning apiece to complete the three-hitter with Hawkins finishing for his second save.
Rockies relievers extended their scoreless streak to 9 2-3 innings in this series.
Anderson left the game with a bruised left index finger after allowing a hit in three innings.
Colorado won for just the second time in six road games this season. It's also just the Rockies' third win in their last 17 games at San Francisco's waterfront ballpark.
A day after pitcher Madison Bumgarner hit a grand slam and drove in five runs, the Giants managed only three hits and were shut out for the first time this season.
Cain (0-2) allowed four hits over seven innings with eight strikeouts and three walks. He is winless in his last seven starts at AT&T Park.
Blackmon, the majors' leading hitter going in, scored the game's only run after leading off the third with a walk. Blackmon took second on Brandon Barnes' infield single, took third as part of a double steal then came home on Tulowitzki's sacrifice fly.
Tulowitzki went hitless in three at-bats in his return to Colorado's lineup after sitting out the series opener with a sore quad. Catcher Wilin Rosario was also back after resting a sore hand on Friday.
Even at full strength, the Rockies needed a big lift from their bullpen to pull this one out.
Anderson lasted just three innings after bruising the index finger on his left hand apparently while grounding out to end the top of the fourth. Anderson took the mound to begin the bottom of the frame before a team trainer was summoned from the dugout.
Anderson eventually walked off the field and was replaced by Kahnle.
Pablo Sandoval greeted the Rockies reliever with a double to the gap in left-center on Kahnle's first pitch after center fielder Blackmon missed on a diving attempt. After Buster Posey walked, Kahnle got Mike Morse to ground into a double play and struck out Hector Sanchez.
The Giants couldn't do much else, spoiling Cain's strongest outing of the season.
San Francisco loaded the bases with two outs in the eighth but Brothers struck out Sandoval on five pitches to end the inning.
