DENVER -- Nolan Arenado homered twice, doubled and singled to drive in a career-high seven runs, rookie Trevor Story had two triples and the Colorado Rockies tied a franchise record with 12 extra-base hits, beating the San Francisco Giants 10-6 on Wednesday night.
The Rockies set a team record with four triples. Story had three of Colorado's 18 hits.
Arenado was one RBI shy of the club mark done four times. He hit a two-run homer in the third inning and added a three-run shot in the eighth that broke open a one-run game.
This was the third time the Rockies have had 12 extra-base hits and the first time since July 30, 2010, against the Chicago Cubs.
San Francisco starter Jake Peavy (0-1) allowed a franchise-high 10 of those extra-base hits. It is the most allowed by a pitcher since Curt Schilling gave up 10 for Boston on Aug. 10, 2006, against Kansas City.
Chris Rusin (1-0) threw 2 1/3 innings to get the win.
Giants rookie Trevor Brown followed Tuesday's two-homer game with two more hits in place of catcher Buster Posey, who sat out his second straight game with a bruise on his right instep.
Story nearly hit two more homers but was kept in the park by the newly raised fence in right-center field and settled for triples each time. His first one hit low on the fence in the third and he scored on Arenado's double.
Story's second drive nearly cleared the screen in the sixth. He looked like he was going to try for an inside-the-park homer but he put on the brakes after rounding third when coach Stu Cole gave him the stop sign. He scored on Carlos Gonzalez's infield single that made it 7-5.
The Giants got one back in the eighth on Brandon Belt's solo home run off reliever Miguel Castro. It was just the second hit allowed by Castro in five appearances.
