Colorado isn't playing well. I understand that. But I don't see the Rockies losing at home with Jon Gray facing rookie Zac Gallen, who has been impressive but has never pitched at Coors Field.

Gray knows how to deal with Coors, the premier hitter's park in the majors. Gray is 5-2 at home with a 3.88 ERA. The Rockies are 6-2 in Gray's past eight home outings.

The Rockies have produced at least five runs in seven of their last 10 games. I see Gallen enduring a painful first experience at Coors.

The Diamondbacks were 0-5 at Coors until beating the Rockies on Monday night.
