| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2020 | Seattle Mariners | 172 | 1.000 | From transactions |
| 2021 | Seattle Mariners | 172 | 2.000 | From transactions |
| 2022 | Kansas City Royals, Seattle Mariners | 107 | 2.107 | From transactions |
| 2023 | Arizona Diamondbacks, Detroit Tigers, New York Yankees | 64 | 2.171 | From transactions |
| 2024 | New York Yankees | 92 | 3.091 | From transactions |
| 2025 | Minnesota Twins | 82 | 4.001 | 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.
