The Colorado Rockies and Arizona Diamondbacks will play the ultimate something-has-to-give game, with the Diamondbacks entering Tuesday 8-50 in their last 58 games and the Rockies at 6-31 on the road this season.

The Rockies send Jon Gray to the mound, who has not had as much success on the road as at Coors Field but has allowed three runs or fewer in four of his last five starts and is 4-3 with a 3.60 ERA in seven career road starts against the Diamondbacks.

The Diamondbacks have six different pitchers that have both made multiple starts and multiple relief appearances, and they own the National League’s worst team ERA at 5.33 and starters registering a 5.48 ERA. They will likely give Merrill Kelly the start on Tuesday, who has allowed at least three runs in eight of his last 11 starts and, despite getting just five wins in 17 starts, leads the team in wins.

Neither team has been stellar at generating power, as the Diamondbacks are 29th in MLB in home runs on a per at-bat basis, and the Rockies are 28th. Arizona pitchers are allowing the most home runs per nine innings in the NL with 1.5.

With Arizona having given up at least five runs in 17 of their last 22 home games, a Rockies lineup that has the MLB’s worst batting average will awaken and power a win.

The play: Rockies, +100.
