| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2019 | Pittsburgh Pirates | 91 | 0.091 | From transactions |
| 2020 | Pittsburgh Pirates | 172 | 1.091 | From transactions |
| 2021 | New York Mets, Pittsburgh Pirates | 53 | 1.144 | From transactions |
| 2022 | Boston Red Sox, Miami Marlins | 0 | 1.144 | From transactions |
| 2023 | Miami Marlins | 7 | 1.151 | From transactions |
| 2024 | Colorado Rockies | 14 | 1.165 | From transactions |
| 2025 | Detroit Tigers, New York Yankees | 7 | 2.000 | From transactions |
| 2026 | Oakland Athletics | 48 | 2.048 | 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.
