Our model's win probability vs. the market's implied probability. The gap is the edge.
Every factor that moved the model. Every number sourced — no hallucinations.
The Cubs open as -132 favorites against the Cardinals despite carrying 15 players on the injury report compared to St. Louis's three. Supreme Brain assigns Chicago a 56.9% win probability versus a 50.0% market-implied probability at the current price, though expected value sits at +0.0% after vig. The model identifies a 0-point injury swing favoring neither side—Tyler Austin, Jameson Taillon, and Hunter Harvey out for Chicago; Ryne Stanek and Ramón Urías sidelined for St. Louis. Chicago outscored opponents by 0.5 runs per game over their last eight contests, while the Cardinals posted a 5-3 record in their recent stretch with a +0.0 run differential. The injury ledger looks lopsided on paper, but St. Louis has stabilized despite absences, making raw momentum the sharper lens for this matchup.
The Cubs carry 15 players on the injury report heading into today's matchup with St. Louis, five times the Cardinals' three absences. Yet Supreme Brain assigns Chicago a 56.9% win probability at -132 odds, a 6.9-point edge over the market's 50.0% implied figure.
The model favors Chicago because the injury gap—despite its optics—produces a 0-point swing in expected impact, and the Cubs have outscored opponents by 0.5 runs per game over their last eight contests while St. Louis has posted a +0.0 run differential despite a 5-3 recent record.
This pick breaks if St. Louis's recent 5-3 stretch reflects genuine talent gains rather than sequencing luck. A +0.0 run differential over that window suggests the Cardinals have been winning one-run games and surviving bullpen volatility, but if their roster adjustments have unlocked a higher gear—particularly in late-inning execution—then the model's injury-neutral stance underrates them. Watch for early-inning run prevention; if St. Louis holds Chicago scoreless through four, the thesis weakens.
The injury report will dominate pregame chatter, but the model sees through the noise. Chicago's edge lives in the box score, not the training room.
