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.

| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −1 | +9 | HOU: Miguel Ullola (no track record yet) · TB: Drew Rasmussen: team allows 0.44 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | TB +53 Elo | TB 57.6% | |
| Market-implied ratings | TB 61.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TB 61.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | TB 63.5% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
