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 | CHW | TB | Why |
|---|---|---|---|

| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −1 | +18 | CHW: Erick Fedde: team allows 0.04 more runs than with its usual starter (≈10 weighted starts) · TB: Nick Martinez: team allows 0.90 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | TB +68 Elo | TB 59.7% | |
| Market-implied ratings | TB 56.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TB 56.5% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | TB 56.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
