How The Model Sees It
Cubs come in 4-6 over their last 10, scoring 3.80 and conceding 3.70 runs a game. Red Sox are 5-5 in their last 10 at 2.20 scored and 2.60 allowed. Red Sox arrive in the better shape, though ten games is a short window and form is weighted lightly here.
On the mound it is Shota Imanaga for Cubs against Tanner Houck for Red Sox — the largest single input on this page. One start moves a baseball projection further than a full lineup change would, which is why the engine waits for both probables before scoring a game.
Season run differential reads +147 for Cubs and +78 for Red Sox. Per game that is 5.25 scored against 4.34 allowed, versus 4.25 and 3.77. Cubs are clearly the better side on the season — and differential is a more honest measure than record, because it survives the luck in one-run games.
Red Sox are 41-40 at home, Cubs 43-38 on the road. Home advantage in baseball is real but small — historically worth something near 54%, not the lopsided edge it carries elsewhere — so the splits inform this projection without dominating it. The ballpark matters more than the venue: run environment varies more between parks than between lineups.
