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 Yankees travel to Tampa Bay as -129 road favorites, and Supreme Brain assigns them a 62.0% win probability against a market-implied 50.0% at the current price. That 12-point gap translates to +5.0% expected value before vig, with a quarter-Kelly stake sizing to 0.13 units. The edge rests on New York's talent and lineup advantages—meaningful separation in a division matchup where Tampa Bay enters with ten players on the injury report compared to eight for the visitors. The Rays retain pitching depth and home-crowd support, but the model sees a road favorite priced below its true win expectancy. At -129, you're laying less than the probability warrants, and that's the entire thesis: a reasonable number on the better roster.
Supreme Brain assigns the Yankees a 62.0% win probability at Tampa Bay, twelve points above the 50.0% market-implied figure at -129 odds. That spread—combined with +5.0% expected value on the current price—frames a road favorite priced below its true win expectancy.
New York's talent and lineup edges justify the model's 62% win probability and create a +5.0% EV opportunity at -129, with a quarter-Kelly stake sizing to 0.13 units.
If Tampa Bay's pitching depth neutralizes the lineup gap—and Supreme Brain acknowledges that depth as a counter-factor—the talent edge narrows and the 62% probability becomes optimistic. The Rays' home crowd adds another layer of variance, and if New York's bats go quiet early, the road-favorite thesis unravels quickly. A first-inning deficit or an unexpected bullpen meltdown would flip the live-betting calculus and erase the pre-game edge.
At -129, you're buying a road favorite below its modeled win rate, and the injury-report disparity only sharpens the picture. The Yankees are the better roster today, and the market hasn't fully priced it in.
