There were still plenty of offensive fireworks.
There was no doubt about Bumgarner’s drive in the fourth. He sent De La Rosa’s first pitch deep into the left field stands for his first home run since 2012.
De La Rosa, Colorado’s opening day starter, failed to make it out of the fifth for the third consecutive start. He struck out six and walked two.
“It looked like his command got away from him,” Rockies manager Walt Weiss said. “He had his ‘A’ game early, then it got away from him.”
Bumgarner wasn’t sharp either and labored most of the game. He threw 112 pitches and gave up four runs, ending a streak of 21 consecutive starts in which he allowed three earned runs or fewer.
Colorado cut it to 6-5 on Charlie Blackmon’s pinch-hit single off reliever Santiago Casilla in the eighth but made two baserunning blunders.
Blackmon strayed too far off second and was thrown out after Casilla made a nice play to spear Jordan Pacheco’s fielder’s choice. Pacheco then got doubled up when San Francisco center fielder Juan Perez caught DJ LeMahieu’s flyball and threw to first.
Romo struck out the side in the ninth for his third save.
The Rockies went up 1-0 in the first when leadoff hitter Brandon Barnes singled and later scored from third while Josh Rutledge was caught trying to steal second.
Rutledge started in place of Tulowitzki and went 3 for 4.
