| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2023 | Seattle Mariners | 55 | 0.055 | From transactions |
| 2024 | Seattle Mariners | 59 | 0.114 | From transactions |
| 2025 | Seattle Mariners | 123 | 1.065 | From transactions |
| 2026 | Seattle Mariners | 172 | 2.065 | From transactions |
172 days credit a full year, so a season adds at most 1.000 no matter how long a player is on a roster. 3.000 years reaches salary arbitration and 6.000 reaches free agency —
what every threshold unlocks.
