Diamondbacks vs Giants Prediction

We saw offense between these teams last night, and I think there’s a carryover effect here. Roupp has a 4.07 ERA and 1.29 WHIP on the season, while Pfaadt has a 5.92 ERA and 1.50 WHIP through 38 innings. Roupp has allowed 28 hits and 17 runs in his last 26.1 innings. Pfaadt is a relief pitcher, but he’s pitched just once this month. There could be some rust there, and allow the Giants to jump on things early. Give me some offense. Give me the over between two pitchers I’m not excited about.
