| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2017 | Miami Marlins | 158 | 0.158 | From transactions |
| 2018 | Miami Marlins | 163 | 1.149 | From transactions |
| 2019 | Miami Marlins | 149 | 2.126 | From transactions |
| 2020 | Pittsburgh Pirates | 172 | 3.126 | From transactions |
| 2021 | Minnesota Twins | 28 | 3.154 | From transactions |
| 2022 | Cincinnati Reds | 7 | 3.161 | 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.
