DENVER - Charlie Blackmon hit two of Colorado's five homers and Jorge De La Rosa threw five efficient innings, lifting the Rockies to an 8-2 victory over the San Francisco Giants on Monday night.
Nolan Arenado, Wilin Rosario and Corey Dickerson also homered for the Rockies, who've won four of the last five. It was Blackmon's first multihomer game of his career.
De La Rosa (1-3) rediscovered his rhythm, allowing five hits and one run for his first victory of the season. The hard-throwing lefty tied a career high with 16 wins last season.
Ryan Vogelsong (0-1) never got on track and was pulled after 11/3 innings, his shortest start with the Giants. He surrendered five runs and six hits, including three homers.
Blackmon lined solo homers in the second and eighth innings. He's hitting .411 this season.
Arenado, who was moved up to the No. 2 spot in the order, extended his hitting streak to a career-high 12 games.
De La Rosa was on the same page with Rosario all night, something that wasn't the case during the season opener in Miami when the battery mates couldn't get their signals straight. Backup catcher Jordan Pacheco has been behind the plate for De La Rosa's past three starts.
But manager Walt Weiss didn't want to create a situation where De La Rosa had a personal catcher, so he went with Rosario.
In the third inning, Rosario sauntered out to the mound to briefly chat with De La Rosa after he loaded the bases with no outs. Whatever Rosario said worked as Buster Posey hit into a 6-4-3 double play - bringing in a run - and Michael Morse flew out to left.
The catcher nicknamed "Baby Bull" also helped his pitcher out at the plate, too, lining a three-run homer. It's his third homer of the season.
Tommy Kahnle took over in the sixth and struck out five in two innings. It's the sixth time a reliever has done that in Rockies history.
