On Tuesday, the Rockies will have Jon Gray on the mound. He is 7-4 with a 4.07 ERA in 16 starts. He has been excellent recently as he hasn’t allowed more than three earned runs in a starts since July 19. In that span, in nine starts, he has an ERA of 2.82.

He’ll be facing Patrick Corbin. From August 12 through September 2, he went 5-0 in five starts with a 0.50 ERA with a .165 opponent batting average (and one of those starts was against the Rockies).
