First pitch is 7:40 PM CT in Denver, and the pitching matchup tells you most of what you need to know about why Pinnacle has the Cubs at -162. Imanaga is 4-6 with a 4.74 ERA but coming off a 6-inning, 5-strikeout no-decision against the A's. Lorenzen is 2-8 with an 8.01 mark that's somehow the actual ERA and not a typo.
The road/home split is the whole story for Lorenzen — a 4.26 ERA away from Coors, a 10.03 disaster in Denver. He's also leading the entire league in hits allowed. His last time out he got cuffed for 8 earned in 3.1 innings against the Angels, and he hasn't found an answer at altitude all year. The Cubs will see a lot of pitches in the strike zone whether they want to or not.
Colorado is 25-42 and just dropped 4 of its last 5, but the one win in there was last night's 7-3 thumping of these same Cubs. Chicago, meanwhile, has lost 3 of 4 and is staring at a rotation held together with duct tape — Justin Steele and Cade Horton are 60-day IL, Jameson Taillon is out until after the All-Star break with a hamstring, and Matthew Boyd at least looks close to a return.

The Rockies' outfield is a triage unit. Brenton Doyle (oblique) hasn't resumed baseball activity, Jordan Beck (hamstring) is only just back to throwing, and Mickey Moniak is still nursing the ankle. Kris Bryant remains a $182M ghost. That's a lot of bats Imanaga doesn't have to navigate, even with the Coors air working against him.
The market read here is straightforward. The number on the Cubs reflects their pitcher and the Rockies' pitcher, in that order. The question is whether you trust a flyball-heavy lefty in the thinnest air in baseball enough to lay the price.
