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 | HOU | Why |
|---|---|---|---|
| Team rating | 1509 | 1530 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +2 | −31 | TB: Shane Baz: team allows 0.10 fewer runs than with its usual starter (≈3 weighted starts) · HOU: Yusei Kikuchi: team allows 1.57 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | HOU +5 Elo | HOU 50.8% | |
| Market-implied ratings | HOU 56.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | HOU 55.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | HOU 59.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
