How the analysis held up
Tampa Bay Rays won, the side Leo's model favored.
Parker Messick (No clear pitching-plan edge) was Leo's favored starter by pitcher score, but Drew Rasmussen actually pitched better tonight: 7.0 IP, 1 ER (1.29 ERA) against 2.0 IP, 2 ER (9.00 ERA). The edge did not show up in this game.
The Tampa Bay Rays bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 2.0 relief innings (0.00 ERA) — quietly better than the pregame read implied.
The Cleveland Guardians bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 1 earned run over 7.0 innings (1.29 ERA) — the risk read did not show up on the scoreboard tonight.

Bullpen matchup
Full Bullpen Fatigue Index →Risk is what the model actually uses: fatigue blended with how well the pen has pitched. High fatigue with high efficiency is a tired pen that is still getting outs.
| Metric | Rays | Guardians |
|---|---|---|
| Fatigue | 5.4/10, Normal | 7.7/10, Tired |
| Efficiency | 4.3/10, Below average | 6.3/10, Effective |
| Combined risk | 5.8/10, Normal | 7.1/10, Tired |
| Relief innings, last 7 days | 13.7 | 21.0 |
| Back-to-back arms | 2 | 4 |
| 7-day ERA | 5.27 | 3.00 |
| 7-day WHIP | 1.32 | 0.90 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
Run total projection
Full Totals Projections →The model projects 2.0 runs below the market total. A research lean still requires a setup rating of at least 7.0/10. Team totals remain research-only until their graded sample is established.
