Rob Donaldson recommends betting three units on the Cubs moneyline at +118 for MLB Opening Day against Zach Gallen and the Diamondbacks. Despite Zach Gallen's big name and strong pitching arsenal, Donaldson highlights his pronounced tendency to struggle with hard-hit percentages. Gallen has consistently posted some of the highest hard-hit rates among pitchers with elite reputations, which adds vulnerability throughout his starts. On the other side, Justin Steele already faced a talented Dodgers lineup early this season and although he struggled initially, Donaldson views that outing as a valuable building point heading into this game. Additionally, the Cubs come into this matchup extra motivated after starting 0-2, losing games to the Dodgers in Japan, making this an ideal spot to back an undervalued, motivated team.
