Adam Rosenberg advised betting Justin Steele under 15.5 pitching outs at -118 odds against the Diamondbacks. Arizona had the fourth-best OPS versus lefty pitchers during spring training and ranked first in baseball in the same metric last season. Steele struggled against the Dodgers in his final spring start and historically performs worse when receiving extra rest, which is the case here. Additionally, the Cubs have no rest days following this start, suggesting a cautious approach and early bullpen usage. Steele has notably struggled against the Diamondbacks previously, going 0-2 with a 4.00 ERA and allowing five and six runs, respectively, in his last two matchups with Arizona. Steele also went under this innings prop in each of his first three starts last year, making this a strong fade scenario. Scott Reichel added important context that current Diamondbacks hitters own a .338 batting average and .372 OBP in 78 career plate appearances versus Steele.
