Arizona Diamondbacks vs. San Diego Padres Prediction
I’m on the under in this one. I just think this is a game where there’s no real expectation of offense between two teams that are out and out struggling. Michael King has been up and down for the Padres this season but he’s still arguably their ace and I think the Diamondbacks have issues here. On the other side the Padres have still had issues putting runs on the board and I’m looking for the under to cash here. Give me the under.
