SAN FRANCISCO -- Colorado Rockies third baseman Nolan Arenado hopes to go down in history as the National League leader in home runs for the 2015 season.
Whether that happens or not, he's already assured himself of an even greater achievement for the record books.
Arenado belted a double and a home run to become the all-time, single-season leader in extra-base hits among third basemen Friday night, helping the Rockies bomb the San Francisco Giants 9-3 in the opener of a three-game, season-ending series.
Left fielder Corey Dickerson also homered, and right-hander Kyle Kendrick pitched six strong innings, helping the Rockies snap a three-game losing streak and clinch the season series against the Giants for the second consecutive year.
"It's humbling," Arenado said. "Chipper had it before me. It's amazing."
His home run, a solo shot in the second inning that opened the Colorado scoring, was his 10th of the season against the Giants. Only former Atlanta Braves outfielder Dale Murphy (11 in 1983) had more in a single season.
"He's killed us," said Giants manager Bruce Bochy. "You look at his numbers, he's killed a lot of teams. But for some reason, we make a lot more mistakes to him."
Arenado leads the league in home runs with 42. His three RBIs increased his season total to 130.
"He just continues to add to his marvelous season," Rockies manager Walt Weiss said. "And he's 24 years old."
Six of Arenado's homers have come at AT&T Park. No other Giants opponent has hit as many in a single season in the 16-year history of the ballpark.
"I love the environment," he said. "When I come to San Francisco, I get a little more pumped up. They are the defending champs. I love the atmosphere."
Added Weiss, "You always want guys to produce against the division. And he's done it on the road. He's done it away from Coors Field, which is important, too."
Like Arenado, Dickerson had a double and a home run, as the Rockies lashed six extra-base hits, five of which came against Giants starter Chris Heston (12-11).
Kendrick (7-13), a pending free agent, bounced back from consecutive six-run outings with one of his best performances of the season.
The veteran allowed five hits and just one run in six innings. He walked one and struck out six.
He also contributed to the Colorado offense with a single, a walk and two runs scored.
Shortstop Jose Reyes had a two-run double among two hits for the Rockies, who totaled nine hits.
Shortstop Brandon Crawford had a two-run double and right fielder Jarrett Parker added an RBI double for the Giants, who were eliminated from the NL West race earlier in the week.
The Giants had eight hits in the game.
Heston, the NL rookie leader in wins, lasted only two outs into the fourth inning, having already allowed eight runs on eight hits. He walked one and struck out three.
"I wanted to take a good one into the offseason," Heston said. "But I can take the whole year and try to build on it."
The big Rockies explosion against the rookie came in the third, when right fielder Carlos Gonzalez had an RBI single, Arenado a two-run double and Dickerson a two-run homer in succession, turning a tie game into a 6-1 Rockies advantage.
The home run was Dickerson's ninth of the season.
