Miami Marlins to win
The market (60%) rates this higher than our model (52%) — no real edge, so we pass.
The model lands on Miami Marlins here, giving them a 52% chance to come out on top against Chicago Cubs. Essentially a coin flip at 52% — entertainment only, not a spot to press. Pitching matchup: Janson Junk (4.11 ERA) vs Shota Imanaga (4.01 ERA).
Why we lean this way
- Form & record: Miami Marlins sit 71-70 (0.504), Chicago Cubs 79-62 (0.560).
- Last 10: Miami Marlins 4-6 (L1), Chicago Cubs 4-6 (W1). Hot streaks move these lines fast.
- Run differential: Miami Marlins +14, Chicago Cubs +133 on the year — the most honest measure of how good a team actually is, beyond their record.
- On the mound: Miami Marlins hand the ball to Janson Junk; Chicago Cubs counter with Shota Imanaga. Starting pitching swings a baseball game more than any other factor.
- Home field: worth about +3.5% to Miami Marlins in our model.
The verdict
