Arizona’s biggest challenge entering this matchup has been offensive consistency. The Diamondbacks hold the lower on-base percentage between these teams, and their pitching staff has also struggled to consistently suppress runs. However, Arizona has still shown enough balance to remain competitive in tight games.
Colorado Hoping Home Field Helps Again
Colorado enters Friday’s matchup with a 17-27 overall record and an 8-11 home record. The Rockies recently lost to Pittsburgh 7-2, 3-1, 6-0, and 9-3 while recently winning over Pittsburgh 10-4. Colorado has dropped four of its last five games and has struggled to consistently slow opposing offenses during that stretch.
The Rockies are batting .249 with 186 runs, 364 hits, and 43 home runs this season. Colorado owns a .317 on-base percentage and a .401 slugging percentage. Defensively, the Rockies have posted a 4.77 ERA and 1.41 WHIP while opponents are hitting .268 against them. Colorado has also recorded 322 strikeouts and issued 142 walks.
Colorado’s biggest strength entering this matchup is offensive production. The Rockies hold advantages in batting average, runs scored, hits, home runs, on-base percentage, and slugging percentage over Arizona. However, the pitching staff has struggled heavily, especially with opponents batting .268 against them this season.
Arizona Diamondbacks vs Colorado Rockies Picks and Prediction
Arizona Diamondbacks vs Colorado Rockies Pick
- Pick: Arizona Diamondbacks Moneyline
Arizona looks like the safer side in this matchup despite recent road struggles. While both starting pitchers have elevated ERA numbers, Arizona still holds the stronger overall pitching profile with a lower ERA, lower WHIP, and lower opponent batting average than Colorado. The Rockies have struggled badly over the last five games and continue to have issues preventing runs consistently. Arizona’s slightly more balanced roster gives the Diamondbacks the edge.
Arizona Diamondbacks vs Colorado Rockies Total Pick
- Pick: Over 12
I am leaning strongly toward the over because both starting pitchers enter with ERA numbers above 6.00, and both pitching staffs have struggled overall this season. Colorado is allowing opponents to hit .268, while Merrill Kelly carries a 7.62 ERA entering the game. The Rockies also own strong offensive numbers with 186 runs and 43 home runs, while Arizona has shown enough offensive ability to contribute in a high-scoring environment. This matchup profiles as one of the highest-scoring games on the board.
Final Score Prediction: Arizona Diamondbacks 8 – Colorado Rockies 6
