Not yet: the Seattle Mariners Doom Index sits at 48 out of 100 today (Watchful), down 1.2 since yesterday. Things are roughly normal by this team's own standards: stay watchful. At 71-82, that makes them the 15th most doomed fanbase in baseball right now.
The biggest drag on the number is Playoff Pulse at 20; the bright spot is Offense at 100. Every signal measures deviation from the Mariners' own season baseline: this is a mood ring, not a power ranking.

|---|---|
| Momentum | 56 |
| Offense | 100 |
| Run Prevention | 46 |
| Playoff Pulse | 20 |
| Regression Watch | 47 |
