Diamondbacks vs Orioles Prediction

The Diamondbacks are 3-1 in their last 4 meetings against the Orioles but the Orioles are 3-2 in their last 5 meetings in Baltimore.

In this Diamondbacks vs Orioles Prediction, the Orioles are coming as -160 home favorites. Both teams have split wins in this series but the Dbacks send Eduardo Rodriguez on the mound and he has been unhittable this season, with just one earned run in three starts. On the flip side, Bradish has at least two earned runs in each of his three starts and the Orioles have been terrible against lefties, with just 3.5 runs/9. I like the plus money with the Dbacks in this spot, so take them on the moneyline on the road.
