In this Rockies vs Diamondbacks Prediction, the Diamondbacks are coming as huge -225 home favorites. The Dbacks are rightfully favored, as they are playing the weakest team in the league, but I don’t trust either pitcher in this matchup, as they have a combined 13.21 combined ERA. Both teams also have bottom-4 bullpens, with a combined 10.39 ERA, and with Arizona having the 7th-best offense in the league with 4.8 runs per game, I expect fireworks offensively in this game. Take the over 9.5 runs.
