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 | CHW | Why |
|---|---|---|---|
| Team rating | 1509 | 1440 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +7 | 0 | TB: Ian Seymour: team allows 0.37 fewer runs than with its usual starter (≈2 weighted starts) · CHW: Shane Smith: team allows 0.00 more runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | TB +59 Elo | TB 58.4% | |
| Market-implied ratings | TB 54.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TB 54.7% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | TB 54.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
