The Diamondbacks finally snapped a three-game skid with a win over the Blue Jays and look to build off a solid offensive showing. Before that, Arizona had scored just seven total runs in three straight losses. Merrill Kelly remains the team’s best and most consistent arm and gives Arizona a big edge on the mound heading into Coors. The lineup has flashed lately, and with Eugenio Suárez is leading the charge with 22 homers and 62 RBI.

On the mound, Arizona is far from elite, but the numbers are better than average. They’ve posted a 4.80 ERA as a team and a 1.35 WHIP, while holding opponents to a .253 batting average. Injuries remain an issue, with Gabriel Moreno, A.J. Puk, and Cristian Pache among several still sidelined. Kelly’s ability to limit walks (22 in 87 IP) and rack up strikeouts (86) makes him the difference-maker. Arizona’s 619 Ks as a staff shows they can miss bats, which is crucial at a hitter’s park like Coors.

The Rockies had been surprisingly hot, winning four straight before falling in extras in D.C. Still, the big picture hasn’t changed much. This is a last-place team with one of the worst home records in baseball. The lineup did show some life, scoring 29 runs over that four-game win streak, with Hunter Goodman swinging it well and now up to 14 home runs and 46 RBI.

Pitching is a mess for Colorado. Palmquist has a 7.76 ERA and 1.76 WHIP through just 26.2 innings, with 16 walks to only 18 strikeouts. Colorado’s team ERA of 5.48 and .290 opponent batting average are both near the bottom of the league. The Rockies have also given up 73 home runs and issued 262 walks. Injuries also remain a concern, with Tovar and Bryant still sidelined.

Merrill Kelly gives the Diamondbacks a massive advantage on the mound, and Arizona’s offense should thrive against Palmquist and a Rockies staff that walks too many and can’t keep the ball in the yard. The Rockies have been playing better lately, but this pitching matchup is lopsided. The numbers back it all up — better ERA, WHIP, and power bats for Arizona. Final Score Prediction: Arizona Diamondbacks wins 7-4.
