| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2019 | Cleveland Indians | 38 | 0.038 | From transactions |
| 2020 | Cleveland Indians | 136 | 1.002 | From transactions |
| 2021 | Cleveland Indians | 156 | 1.158 | From transactions |
| 2022 | Boston Red Sox, Cleveland Indians, Pittsburgh Pirates, Tampa Bay Rays | 170 | 2.156 | From transactions |
| 2023 | Boston Red Sox | 131 | 3.115 | 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.
