If you're genuinely worried about this, bet Game 1:
GREEN / YELLOW DET @ NYM Game 1: A later inning shower isn't impossible, but it's not too likely. I expect they play 9 without issue. Cold with winds left to right at 10mph.
YELLOW DET @ NYM Game 2: Slightly better rain chances here, though for now high-res models keep everything south of the ballpark. It's close enough that we'll need a radar check pre-game to make sure everything is behaving. Cold, winds left to right at 10mph.
I just started betting on MLB last season. I watched your thread for a couple weeks and figured out the thought process behind taking 5 innings , The Lefty / Righty match ups etc.... So I get nervous when I think I have a great play and its the opposite that everyone is backing today. lol
