| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2017 | Tampa Bay Rays | 154 | 0.154 | From transactions |
| 2018 | Tampa Bay Rays | 172 | 1.154 | From transactions |
| 2019 | Tampa Bay Rays | 157 | 2.139 | From transactions |
| 2020 | San Francisco Giants | 58 | 3.025 | From transactions |
| 2021 | Milwaukee Brewers | 97 | 3.122 | 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.
