| Season | Club | Days | Running total | How this season is known |

| 2018 | Tampa Bay Rays | 68 | 0.068 | From transactions |
| 2019 | Tampa Bay Rays | 113 | 1.009 | From transactions |
| 2020 | Tampa Bay Rays | 172 | 2.009 | From transactions |
| 2021 | Pittsburgh Pirates | 172 | 3.009 | From transactions |
| 2022 | New York Mets, Pittsburgh Pirates | 81 | 3.090 | From transactions |
| 2023 | New York Mets | 13 | 3.103 | 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.
