Diamondbacks vs Cubs MLB Betting Preview
Action PRO projects Cubs CF Pete Crow-Armstrong for 0.72 RBIs in their matchup against the Diamondbacks this afternoon, giving us a 10.5% edge against the market when compared to his current prop line of over/under 0.5, which is good enough to mark the over with a B grade in our system.
He is coming off a 2025 season with 95 runs batted in, and he drove in six runs in the last four games.
Crow-Armstrong will face Merrill Kelly, a starter with a 9.20 ERA who should provide plenty of opportunities for the Cubs to score at Wrigley Field today.
At plus money, let's back PCA to go over his RBI line against Arizona.
Pick: Pete Crow-Armstrong Over 0.5 RBIs (+140, BetMGM)
