As the Rockies flirt with the first 100-loss season in franchise history, they are sinking rapidly into National League West oblivion. On a 95-degree Wednesday afternoon, they lost a 9-7 Coors Field slugfest to the Diamondbacks. The loss dropped the Rockies’ record to 2-8 against the D-backs this season and left the Rockies a combined 8-27 against all of their NL West foes.
