I'm playing on HOUSTON. While the Astros are 18-7 at home, the Dbax are 8-19 on the road. Greinke will make his first start against the Dbax since he played for them. He knows how important these games are and he's going to be highly motivated to deliver. Gallen has come back to earth this month. Arizona is 0-3 in his starts this month and he's got a 5.82 ERA to show for it. Gallen is backed by an Arizona bullpen which has an ERA above five on the road. Greinke, on the other hand, has the support of a Houston bullpen which has an ERA below four at home. The Astros got back to 500 with yesterday's win. They know they need to keep winning and I expect them to take advantage of an Arizona team which struggles on the road.
