Colorado Rockies vs Arizona Diamondbacks Prediction and Picks, September 23, 2026

The Colorado Rockies are listed as underdogs at +134, which gives them a real chance to pull off a win against the Arizona Diamondbacks. While the Rockies have struggled lately, winning only 2 of their last 10 games, they have often found themselves ahead after five innings, showing they can compete early in matches. The Diamondbacks have also been up and down, winning 4 of their last 10 games. This matchup is close, and the Rockies playing at home in Coors Field can be an advantage. Just keep in mind that the Rockies have only won 2 of their last 6 games, which makes this a bit risky.

Colorado Rockies vs Arizona Diamondbacks: Colorado Rockies +1.5 Spread (-112)

The odds for the Colorado Rockies at +1.5 look pretty good considering how close this matchup is. The Rockies have struggled lately, winning just 2 of their last 10 games, but they have been competitive at home. They have often been ahead after five innings, which shows they can hold their own early on. The Diamondbacks are also finding their footing, winning 4 of their last 10, but the teams are very evenly matched right now. One risk here is that the Rockies have lost quite a few games recently, which makes this a tough pick. Still, since this game is at Coors Field, the Rockies could surprise against a Diamondbacks team that hasn't been super dominant either. With the spread at +1.5, it feels like a solid opportunity to take a chance on the home team.
