Arizona Diamondbacks vs Colorado Rockies Prediction, Odds and Picks for Friday, 06/20/25

Don’t look now, but the Rockies have won 4 of their last 5 games and have scored a total of 32 runs in that span (6.4 runs per game). After a 7-game road trip, they now return home to Coors Field where their offense has been substantially better. That isn’t necessarily surprising given the hitter-friendly nature of Coors Field, but it’s worth noting that Colorado’s team batting average jumps from .205 on the road to .250 at home. Furthermore, their OPS goes from .615 to .738. Arizona starting pitcher Zac Gallen has had a disappointing 2025 campaign thus far, as he enters this matchup with a 5.19 ERA and has issued 40 walks in 86.2 innings. If Gallen is off his game and issues free passes, Colorado’s offense could be ready to pounce.

On the other side, the Arizona offense has been among the best in baseball for most of the season. The Diamondbacks are in the top-5 of the league in several major statistical categories including runs, home runs, and OPS. Austin Gomber will be making his second start of the season after beginning the campaign on the IL. His first start went well, but he faced an Atlanta lineup that has struggled for most of the season. The Arizona offense presents a much tougher challenge. Even with a high total, consider the over.
