The price is worth laying considering Arizona's road record (15-38 in its last 53 away games), 4-12 mark in its last 16 games versus a left-handed starter and Josh Collmenter's struggles at Coors Field.



Colorado plays much better at home. The Rockies are 17-7 in their last 24 games at Coors Field and have steady southpaw Tyler Matzek on the mound on extra rest. Matzek hasn't given up more than two runs during any of his four starts this year posting a 2-0 record with a 2.70 ERA. Matzek is 2-1 lifetime versus Arizona with a 2.65 ERA in three starts. Colorado has won seven of Matzek's past 10 starts.



Collmenter has had problems at Coors going 0-1 there with a 5.49 ERA in four career starts. Troy Tulowitzki, Carlos Gonzalez, Charlie Blackmon and Nick Hundley are a combined 22-for-63 versus Collmenter for a batting average of .349.
