TL;DR
Supreme Brain assigns the Dodgers run line a 54.5% win probability against a 50.0% market-implied probability at -110 odds, producing a +4.0% edge on this market at the current price. The model's quarter-Kelly stake sizes to 0.01 units at this edge—modest conviction, but real value. Both clubs carry heavy injury reports into today's slate: Arizona lists 12 players, Los Angeles 14. The gap isn't in health; it's in the market's failure to price the Dodgers' multi-run upside correctly. At -110, you're getting a coin-flip price on a better-than-even proposition. The edge is narrow, the variance is real, and the sample is one game. But when the model sees 4.5 percentage points of daylight between probability and price, you take the number and let the long run do its work.
Supreme Brain assigns the Dodgers run line a 54.5% win probability against a 50.0% market-implied probability at -110 odds. That 4.5-point gap is the entire thesis.
Los Angeles at -1.5 offers a +4.0% expected-value edge because the market is pricing this as a coin flip when the model sees a better-than-even proposition—54.5% to cover multiple runs against Arizona today.
Why we like it
- The pricing inefficiency is straightforward: -110 odds imply a 50.0% probability, but Supreme Brain's model assigns LAD -1.5 a 54.5% chance to cover. That 4.5-percentage-point spread translates to a +4.0% expected value at the current price. You're buying a modest favorite at coin-flip odds.
- Both rosters are battered—Arizona carries 12 players on the injury report at game time, Los Angeles 14—but the Dodgers' depth has historically absorbed attrition better in multi-run scenarios. The injury ledger is nearly identical, so the edge isn't health; it's the market underpricing LA's ability to win by two or more.
- Quarter-Kelly stake sizing at this edge lands at 0.01 units, or $10 at the current bankroll. That's a signal: the model likes the number, but it's not screaming. Modest conviction, real value, and a narrow margin for error.
How this loses
If Arizona's offense finds early rhythm and keeps the game within one run through seven innings, the run line dies on the vine. The Dodgers need separation—ideally a multi-run inning before the sixth—to render late-game variance irrelevant. A tight, low-scoring affair flips this pick from +EV to a bad beat.
The model sees 54.5% where the market sees 50.0%. That's the edge. Take the number, size it appropriately, and let probability do the rest.
