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 | TB | BOS | Why |
|---|---|---|---|
| Team rating | 1517 | 1526 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +1 | +12 | TB: Griffin Jax: team allows 0.04 fewer runs than with its usual starter (≈8 weighted starts) · BOS: Jake Bennett: team allows 0.60 fewer runs than with its usual starter (≈6 weighted starts) |
| Elo ratings | BOS +38 Elo | BOS 55.4% | |
| Market-implied ratings | TB 51.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TB 50.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | BOS 52.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
