Diamondbacks vs Giants Prediction

The Diamondbacks won six of the previous ten H2H encounters, including three of four H2Hs this season. Also, six of the last ten H2Hs went Over, and I am going with another one here because of the pitching matchup. Hayden Birdsong had a disappointing June, during which he posted a 6.38 ERA and allowed multiple runs in his previous four starts. In his latest start against Arizona, Birdsong allowed three runs in 3.0 innings, as the D-backs won 8-7. Zac Gallen, on the other hand, surrendered 4+ runs in eight of his last nine starts, and I don;t think he will be able to contain the Giants here. Go with Over.
