The Diamondbacks have been one of the best home sides all season as they held a 52-29 record.
They also have a major advantage with All-Star Zach Greinke on the mound.
He has a 13-1 record at home in 2017 with a 2.87 ERA.
The D-Backs have a 16-3 record in his 19 home starts as well.
But interestingly, the Rockies won two of those three games.
So they are a chance of an upset.
The Rockies are starting Jon Gray and he earned a win in his last start in Arizona.
The Rockies won 4-2 and he pitched 7 strong innings.
Overall, the Rockies are 4-0 in his last 4 away starts as well.
In the last 2 months of the season, Gray had an ERA of under 2.57 so he’s capable of keeping the Rockies in this one.
The Rockies have a good record in Arizona and the Wolf is predicting a very close game.
So he’s going for the Rockies +1.5 in a possible 5-4 scoreline in the Diamondbacks favour.
