The San Diego Padres are -140 favorites to take the series lead over the Arizona Diamondbacks on Wednesday night.
I think the home team is overpriced, and my Diamondbacks vs. Padres predictions and MLB picks reflect that on July 8.
Who will win Diamondbacks vs Padres today: Diamondbacks moneyline (+120)
Michael King’s profile is littered with red flags. His 5.08 xERA and 5.14 FIP are noticeably higher than his 3.81 ERA over the last month, indicating he is poised to take a step back.
The Arizona Diamondbacks haven’t hit righties well of late but they’ve avoided strikeouts, ranking 25th in K% over the last two weeks. That should allow them to put the ball in play consistently.
The San Diego Padres rank dead last in GB% vs. righties the past 30 days, putting a cap on their offensive ceiling.
Back Arizona to +110.

Diamondbacks vs Padres Over/Under pick: Under 8.5 (-115)
For King’s faults, he does a good job of keeping the ball in the park. He has allowed 0.88 homers per nine innings this season, and playing in a pitcher-friendly environment against a team sitting dead last in homers per fly ball will make his life easier.
The Padres have improved their averages of late but they are still consistently putting the ball in the dirt, limiting their power.
Neither team is much of a homer threat, and it’s difficult to score in bulk without quick-strike attacks.
Bet the Under to -125.
