| 2021 | Miami Marlins | 172 | 1.000 | From transactions |
| 2022 | Toronto Blue Jays, Miami Marlins | 96 | 1.096 | From transactions |
| 2023 | Toronto Blue Jays | 102 | 2.026 | From transactions |
| 2024 | Toronto Blue Jays | 147 | 3.001 | From transactions |
| 2025 | New York Mets, Seattle Mariners | 27 | 3.028 | From transactions |
| 2026 | Philadelphia Phillies | 66 | 3.094 | 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.
