| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2021 | Arizona Diamondbacks | 47 | 0.047 | From transactions |
| 2022 | Cincinnati Reds, Seattle Mariners, San Francisco Giants | 86 | 0.133 | From transactions |
| 2023 | Cincinnati Reds | 150 | 1.111 | From transactions |
| 2024 | Cincinnati Reds | 172 | 2.111 | From transactions |
| 2025 | Atlanta Braves | 172 | 3.111 | From transactions |
| 2026 | Cleveland Indians, Seattle Mariners | 37 | 3.148 | 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.
