For the first time in club history the Colorado Rockies have scored two or fewer runs in consecutive home games and won both, stifling the Cardinals 2-1 on Wednesday for the second time in as many days. In a curious role reversal that is striding toward a full-blown concern for the Cardinals, they’ve been unable to solve a mile above sea level the same Colorado starters they punished riverside in St. Louis. Ian Desmond’s solo homer off Dakota Hudson broke the 1-1 tie in the sixth and proved the difference as the Cardinals grounded into three double plays, including one in the ninth inning.
