Diamondbacks vs Padres MLB Betting Preview
This is Sean Zerillo’s largest projected edge on today’s slate, as you can see via our new PRO baseball betting tool, BARTOLO.
Diamondbacks vs Padres Pick, Betting Analysis
I think a large part of the projected edge comes from the umpire. Lance Barksdale is one of the most hitter-friendly umpires in the sport. Derek Carty’s THE BAT X rates him as the fifth-most hitter-friendly umpire in MLB (4.14 ERA), and Zerillo has adjusted his projection up a full 4% for Barksdale alone.
But regardless of umpire, it’s not hard to bet an Over in a pitching matchup between Zac Gallen and German Marquez.
Marquez’s rolling CSW rate is now under 20%, and his rolling xFIP has jumped to over seven as a result.
The hope that going from Coors to PetCo would revive German seems to be a lost cause now. He can’t miss bats, so he tries to nibble the zone, which results in walks. When he does throw stuff in the zone, he allows loads of hard contact because his stuff is horrific — he has one above-average pitch in his arsenal per Stuff+, the knuckle-curve, which is running a career-low, MLB-average 100 Stuff+ rating.
Marquez has also struggled to get lefties out this year (.415 wOBA allowed, -1.2% K-BB rate). Ketel Marte and Geraldo Perdomo are switch-hitters who will bat from the south side in this matchup, creating a left-handed trio atop the order with Corbin Carroll — that really sucks for German.
I also just really like this Snakes offense. The lineup has elite talent at the top but depth all the way down. They are patient but have pop.
Unfortunately for them, Zac Gallen is a shell of his former self.
He’s allowed 55 earned runs over his past 63 innings. He’s posting career-low rates in stuff, swing-and-miss, strikeout, and all his batted-ball numbers have cratered. Hitters are smashing his fastballs in the zone and not chasing his curveball out of the zone (or really any of his secondary stuff).
Unless there’s a drastic change in his style and arsenal soon, things will likely stay ugly.
I’m worried about this Over because I like both these bullpens, I like both these defenses, and PetCo is typically a pitcher’s park.
However, Adrian Morejon is likely out for the Padres today after throwing 62 pitches over the past three days, and San Diego’s defense doesn’t project well via BARTOLO. Also, San Diego’s lineup has serious pop.
I feel like this has blowup potential for one or both starters written all over it, and I think a juiced 8.5 is a good price — this number should be at least nine.
If you want to target the early game or innings — like a YRFI or F5 Over — I don’t hate that either. This feels like much of the scoring will come against the starters at the top of the lineup, especially for Arizona against Marquez.
Pick: Over 8.5 (-125 or Better)
