How the analysis held up
Tampa Bay Rays won, the side LyDia's model favored.
Drew Rasmussen (Tampa Bay Rays) was LyDia's favored starter by pitcher score, but Robbie Ray actually pitched better tonight: 6.0 IP, 1 ER (1.50 ERA) against 6.0 IP, 2 ER (3.00 ERA). The edge did not show up in this game.
The San Diego Padres bullpen was not flagged pregame, but it had a night worth noting: 3 earned runs allowed over 4.1 relief innings (6.23 ERA) — quietly worse than the pregame read implied. Note: 1 of the runs charged to the San Diego Padres pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
The Tampa Bay Rays bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 5.0 relief innings (0.00 ERA) — quietly better than the pregame read implied. Note: 2 of the runs charged to the Tampa Bay Rays pitching staff overall were unearned — not something the bullpen's stuff should be blamed for.
San Diego Padres scored 4 in a game that went 11 innings — not compared against the 3.9 pregame projection, which assumed nine.
Tampa Bay Rays scored 5 in a game that went 11 innings — not compared against the 4 pregame projection, which assumed nine.

The Map

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 | Padres | Rays |
|---|---|---|
| Fatigue | 5.4/10, Normal | 6.0/10, Normal |
| Efficiency | 6.5/10, Effective | 6.2/10, Effective |
| Combined risk | 4.7/10, Normal | 5.4/10, Normal |
| Relief innings, last 7 days | 21.7 | 21.0 |
| Back-to-back arms | 3 | 4 |
| 7-day ERA | 1.66 | 3.00 |
| 7-day WHIP | 1.34 | 0.95 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
