Diamondbacks vs Cardinals Prediction

The Cardinals won six of the previous ten H2H encounters. I am backing the Cards in this one because of a favorable pitching matchup. When I say favorable, I mean I am betting against Zac Gallen here, as he struggled recently. Gallen allowed ten runs in his last two starts and allowed a .325 BA in 40 at-bats against the Cardinals. Miles Mikolas, on the other hand, surrendered just four runs in his previous five starts, three of which were shutouts. I have faith in Mikolas to produce another strong start, so make sure to back the Cardinals.
