Since the pitching match-ups haven't been set as of yet, FiveThirtyEight has their odds just based on the rest of the team.
Cleveland gets the edge 52% to 48% when they are at home
Blue Jays get the edge 57% to 43% when they are at home
Seems like the pitching match-ups will play a very big roll as expected, and maybe even moreso on the road than at home.
