Barry Enright outdueled Ubaldo Jimenez and Justin Upton hit a two-run homer as the Arizona Diamondbacks topped the Colorado Rockies 3-1 Saturday.

Three relievers bridged the gap to Juan Gutierrez, who worked the ninth for his fourth save for the Diamondbacks. Arizona has taken the first two games of the series after dropping four in a row.

Enright (4-2) yielded just one run on three hits while walking two and striking out four as he continued a brilliant start to his career. The 24-year-old right-hander has allowed three runs or less in each of his first 10 major-league starts.

Jimenez (17-4) was almost as good, yielding just three hits. He had the lead until his wild pitch allowed Upton to score in the fourth, knotting the game at 1-1. Upton struck again in the sixth after Enright’s one-out single, driving his 17th homer of the season over the wall in left to give Arizona a 3-1 edge.

Jimenez has not won in his last three starts despite strong outings in each as the Rockies offense has struggled to support its ace.
