How the number is built
Elo inputs in rating points (higher favors that team; 25–28 Elo is about a point of spread in football and basketball), then how the pieces combine.
| Factor | KC | TB | Why |
|---|---|---|---|

| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −10 | −6 | KC: Noah Cameron: team allows 0.49 more runs than with its usual starter (≈10 weighted starts) · TB: Griffin Jax: team allows 0.29 more runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | TB +36 Elo | TB 55.2% | |
| Market-implied ratings | TB 57.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TB 57.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | TB 58.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
