Cubs at Diamondbacks

O/U 8 · RL Cubs -1.5 · Chase Field

GARY'S PICK

MLBvs Cubs· -102

I’m backing Arizona straight up. Brandon Pfaadt is the separator: he owns a 1.71 ERA in August and, before allowing five earned runs at Boston, had delivered four consecutive scoreless starts. His 2.83 ERA in six home starts also compares favorably with Clay Holmes’ 2.91 road ERA. Holmes has been effective overall, but he has made only three starts since returning from an 85-day absence and has completed six innings once. Chicago’s offense and recent bullpen form are the dangers. The Cubs average 5.2 runs per game to Arizona’s 4.5, and their bullpen has a 2.28 ERA over the last seven games versus 5.12 for the Diamondbacks. But Monday’s 7-0 result is exactly what makes this home-side price attractive. My read is that Pfaadt reestablishes the form he carried into Boston and keeps Arizona away from the vulnerable portion of its bullpen. The +1.5 protection costs -184, and that is not the bet this read calls for. Arizona needs to win for the starting-pitcher advantage to matter enough, so I’ll take the Diamondbacks moneyline at -102.

The read

Chicago’s offense and recent bullpen form are the dangers. The Cubs average 5.2 runs per game to Arizona’s 4.5, and their bullpen has a 2.28 ERA over the last seven games versus 5.12 for the Diamondbacks. But Monday’s 7-0 result is exactly what makes this home-side price attractive. My read is that Pfaadt reestablishes the form he carried into Boston and keeps Arizona away from the vulnerable portion of its bullpen.

The +1.5 protection costs -184, and that is not the bet this read calls for. Arizona needs to win for the starting-pitcher advantage to matter enough, so I’ll take the Diamondbacks moneyline at -102.

The research

The dated measurements the app shows under this card — observations with their sample and source, not predictions.

BATTER VS ARM

Brandon Pfaadt vs Seiya Suzuki: 0-for-11, 5 K
0-for-11
Suzuki simply can't find the barrel against Pfaadt — 0-for-11 with five strikeouts isn't a couple of unlucky at-bats. I like the under on his hits tonight, and Pfaadt's strikeout total holds appeal too.

HEAT CHECK

Alex Bregman: 1.167 OPS in Last 15 Days
1.167
Fifty plate appearances well above an already-solid season line points to a veteran finding another gear, not padding stats. Nineteen bombs on the year, I'm comfortable with his 1.5 total bases tonight.
Corbin Carroll: 1.174 OPS in Last 15 Days
1.174
Carroll was already one of the better bats in the league at .842 for the season, and pushing this much higher over 46 trips is a strong year compounding, not garbage against weak arms. I like his 1.5 total bases tonight.

BULLPEN

Arizona Diamondbacks pen: 15 relief IP over their last 3 games
15 IP
Clarke's out after back-to-backs and Ginkel's gone twice too — Arizona's cycled through nearly its whole pen without one arm stepping up for real length. The Cubs want this bullpen turning over arm after arm tonight, not settling into trusted innings.

HEAD-TO-HEAD

Cubs are 5-1 vs Diamondbacks this season
5-1
Cubs are 5-1 against Arizona this year and that finale was a 7-0 beatdown, not a nail-biter. The Diamondbacks have to actually solve something tonight, not just hope the numbers regress.

TEAM RECORD

Diamondbacks 7-1 in Brandon Pfaadt's last 8 starts
7-1
Arizona's 7-1 behind Pfaadt isn't a coincidence — that's a lineup and pen that both show up specifically on his turns. Same script, same building tonight against the Cubs, and home is where this group is most dangerous.

REGRESSION

Clay Holmes: 2.49 ERA vs 4.05 xERA
4.05
Holmes is getting touched — 41.9% hard-hit — but barely any of it's squared up clean at just a 4.9% barrel rate, and that's a repeatable skill, not noise. There's still some fortune in the average-against gap, but he's got more going for him tonight against Arizona than the raw ERA suggests.
Nico Hoerner: .262 AVG vs .299 xBA
.299
This one runs the other way — Hoerner's average is sitting well below what his contact quality earns, and over 566 plate appearances that's not noise. I'd expect the hits to start landing again against Arizona tonight.

CLOSER WATCH

Brandyn Garcia / Kevin Ginkel
4 SV
Garcia's out front 4-2 in saves, but 14 holds next to just 4 saves tells you this has been more setup-man usage than a clean ninth-inning gig, and with Ginkel within 2 it's an honest committee, not a clear alpha. Arizona's tight favorites at -108 at home against the Cubs, so there should be a save chance on the table tonight. Garcia's thrown once in the last three games and is fully rested, so workload isn't holding him back if the Snakes get the call. Live spot for Garcia if you already have him, since the price says a ninth-inning chance is in play. But this is a real timeshare — if you're hunting saves this week, you want Ginkel rostered too, not just the guy nominally in front.
