| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2019 | Miami Marlins | 56 | 0.056 | From transactions |
| 2020 | Miami Marlins | 172 | 1.056 | From transactions |
| 2021 | Miami Marlins | 114 | 1.170 | From transactions |
| 2022 | Miami Marlins, San Francisco Giants | 0 | 1.170 | From transactions |
| 2023 | Detroit Tigers, San Francisco Giants | 12 | 2.010 | 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.
