[AZ Central] Diamondbacks' funk continues with loss to Rockies - The past two weeks have not resembled that 2-15 skid from two months ago; unlike before, the Diamondbacks’ offense is now performing at least at a competent level. Their losses have been close, competitive. Of late, their issues have been in the starting rotation, which has produced just two quality starts this month and none in the past week. To that end, left-hander Robbie Ray’s performance on Thursday was encouraging, despite the end result. Ray had struggled in his previous two starts and has yet to find the level of consistency or dominance he achieved for most of last season.
