The Rockies should be fine returning to Coors Field where they have won six of their last eight games. German Marquez knows how to pitch there. Marquez is in good form with a 2.37 ERA in his last three starts. 

The Rangers have lost 12 consecutive road games. They figure to have trouble at Coors Field. Dane Dunning gets the start for them. 
Dunning looked good early in the season, but he's fallen on hard times. He gave up seven runs on seven hits in just four innings this past Wednesday to the Angels.

Dunning is 0-3 with a 7.97 ERA in five road starts this season.
