Arizona Diamondbacks vs Colorado Rockies Spread Pick
- Arizona Diamondbacks
The Diamondbacks have the advantage because of stronger recent pitching and a clear edge in the starting matchup. Soroka has delivered quality outings consistently over the last two weeks, while Lorenzen has struggled badly, giving up too many hits and allowing too many baserunners. Arizona also enters with momentum after the 9-1 victory Friday night, putting the Diamondbacks in a strong position to win.
Arizona Diamondbacks vs Colorado Rockies Over/Under Pick
- Over
This game will cash over as Colorado’s pitching continues to struggle at Coors Field. The Rockies have allowed 25 runs across their last four losses, and both teams have enough power hitters to capitalize on extra baserunners. With Lorenzen carrying a 6.55 ERA and Arizona swinging the bats well recently, scoring opportunities should be available throughout the matchup.
