The Rockies are usually a good fade on the road. That should be the case here. 
Colorado has lost 39 of its last 54 away games. They are starting German Marquez and have one of the worst bullpens on paper. The Rockies' best reliever, Scott Oberg, is on the DL with a back strain.
I like Texas starter Lance Lynn more than Marquez. The veteran Lynn won't lack motivation making his first Opening Day start. He hasn't pitched against the Rockies in three years, but has a 2.76 ERA and 1.16 WHIP versus them in seven career starts.
