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 | ARI | TB | Why |
|---|---|---|---|
| Team rating | 1532 | 1504 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +9 | +20 | ARI: Zac Gallen: team allows 0.43 fewer runs than with its usual starter (≈10 weighted starts) · TB: Jeffrey Springs: team allows 0.98 fewer runs than with its usual starter (≈5 weighted starts) |
| Elo ratings | TB +1 Elo | TB 50.2% | |
| Market-implied ratings | ARI 54.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | ARI 53.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ARI 52.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
