I see there is no article in advance of Colorado-Arizona, though there was for NYY-Twins.  In these one game showdowns, anything can happen of course, but Arizona is the better team. The Rockies have a formidable top of their batting order, but away from Coors Field, those same guys are not as formidable. Arizona will also throw Zack Greinke out there, who is something like 13-1 at home, though, 2-1 against Colorado, and including decisions not affecting him, the Dbacks were 2-3 against Colorado when Greinke started. 

Most Dodger fans I know, few as they are, would rather face Colorado. This includes me, though I am mindful of the "be careful what you wish for" statements that come back to bite you.  But against Arizona, you face Robbie Ray twice, who more or less owned the Dodgers this year, Goldschmidt, and JD Martinez, who was the best near trade deadline acquisition that any team made.
