| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2021 | San Francisco Giants | 71 | 0.071 | From transactions |
| 2022 | San Francisco Giants | 129 | 1.028 | From transactions |
| 2023 | Oakland Athletics | 117 | 1.145 | From transactions |
| 2024 | Kansas City Royals | 134 | 2.107 | From transactions |
| 2025 | Kansas City Royals | 172 | 3.107 | 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.
