DENVER — Nolan Arenado and Carlos Gonzalez hit back-to-back homers in the first inning, backing a strong outing by Jorge De La Rosa, and the Colorado Rockies beat San Francisco 2-1 on Friday night to send the Giants to their seventh straight loss.
De La Rosa (9-6) allowed one run and six hits in seven innings. He didn’t walk a batter and struck out seven. Two of the strikeouts came in the sixth inning, helping him get out of a jam and he induced an inning-ending double play grounder from Juan Perez after giving up a one-out single to Kelby Tomlinson in the seventh.
Chris Heston (11-9) went 5 2-3 innings for the Giants and allowed seven hits and two runs, both on the solo homers in the first.
John Axford worked a scorless ninth for his 19th save.
