The San Diego Padres were blown out by the Arizona Diamondbacks in the series opener of this NL West battle.
My Diamondbacks vs. Padres predictions and MLB picks see value in backing the home team to respond in Game 2.
Who will win Diamondbacks vs Padres today: Padres moneyline (-125)
Neither offense is potent against right-handed pitching, but the San Diego Padres are in better form. They are +1.6 weighted runs above average vs. righties over the last month, while the Arizona Diamondbacks come in at -12.4.
The Padres have potential for a ceiling performance against Zac Gallen, who has posted a 5.85 xERA or worse in seven consecutive starts — and conceded at least four runs in six of them.
If German Marquez can pitch an inning or two, Johnny Brito and his extreme ground-ball profile in the minors should help him survive. Bet this to -135.
COVERS INTEL: Zac Gallen has been one of the league's worst pitchers, ranking in the second percentile in pitcher run value.
Diamondbacks vs Padres Over/Under pick: Over 9 (-105)
These offenses are nothing to write home about, and I’m not sure it matters. The pitching is that poor.
Gallen has posted a 7.24 ERA over his past 12 starts, conceding an average of 4.6 runs when he takes the bump. Only once during that stretch did he allow fewer than three runs.
The Padres are going with Marquez as an opener, a minor leaguer in bulk, then turning to a bullpen that ranks dead last in FIP over the past two weeks.
I like the Over and would play it to -115.
- ML/RL bets: 51-41, -0.15 units
- Over/Under bets: 50-39-4, +6.39 units
