Diamondbacks vs Padres Prediction

The Padres are 8-2 in their last 10 meetings against the Diamondbacks and are 5-1 in their last 6 meetings in San Diego.

In this Diamondbacks vs Padres Prediction, the Padres are coming as -125 home favorites. I don’t like either pitcher in this matchup, as they both have a combined 12.42 ERA and 1.50+ WHIP each. They both have been in very bad form, as Kelly has given up 16 runs across his last four starts while Canning has a 6.75 ERA across his last three starts. Yesterday’s game between those two teams had 14 total runs and I expect another high-scoring affair today. Take the over 8.5 runs.
