PHOENIX — The Rockies’ win streak screeched to a halt Sunday afternoon at Chase Field. Given Colorado’s track record on Sundays, and given that Arizona right-hander Zack Greinke was dealing like an ace, the outcome was not a big surprise. Greinke struck out 13 over his eight sterling innings as the Diamondbacks whipped the Rockies 6-1, definitively halting the seven-game run that put Colorado back in the hunt for the National League West title. Boxscore Colorado fell to 4-12 on Sundays, despite the fact that manager Bud Black continues to start most of his regulars on a day when some other managers choose to give players a day of rest. The Rockies slipped to third place in the NL West, two games behind the division-leading Dodgers, who routed Milwaukee 11-2 Sunday, and a half-game behind the Diamondbacks. Sunday hex or no Sunday hex, the biggest factor in Arizona’s victory was Greinke’s dominating performance.
