Diamondbacks vs Pirates Prediction


The Pirates are 4-1 in their last 5 meetings against the Diamondbacks and have won their last two meetings in Pittsburgh.

In this Diamondbacks vs Pirates Prediction, the Pirates are coming as -120 home favorites. I don’t trust either pitcher in this matchup, as they both have a combined 10.02 ERA and both offenses have been red-hot lately, averaging 11.5 runs per game combined in their last 10 games. On top of that, both bullpens have been bottom-8 in the league after the break and they are 7-2 to the over in their last 9 games combined, so I am expecting a high-scoring affair today. Take the over 9 runs.
