Mariners vs Diamondbacks Prediction
The teams have traded wins in the past couple of years, each recording five in the previous ten H2H encounters. Brandon Pfaadt has been struggling lately on the mound, which is the biggest reason I am going with Over. I’d back the Mariners to win, but I don’t trust rookie Evans, who is in a way better form than Pfaadt. Arizona is one of the best offensive teams in the league, and I don’t believe Evans will get a quality start here. I am backing the D-backs to score 3+ runs off him. Pfaadt, on the other hand, allowed 3+ runs in each of his previous five starts. He will continue to struggle here. Back the Over.
