DENVER — Nolan Arenado came through with another big swing for the Colorado Rockies.
Arenado hit a two-run triple off Zack Greinke in the eighth inning, and the streaking Rockies rallied past the Arizona Diamondbacks 4-3 on Tuesday night in the opening game of their NL West showdown.
Carlos Gonzalez homered and saved a run with a diving catch to help Colorado win its sixth straight. The NL West leaders extended their advantage to two games over third-place Arizona, which had won seven in a row. Second-place Los Angeles remained a half-game back of the Rockies after routing the New York Mets.
