| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2017 | Milwaukee Brewers | 31 | 0.031 | From transactions |
| 2018 | Milwaukee Brewers | 167 | 1.026 | From transactions |
| 2019 | Milwaukee Brewers | 60 | 1.086 | From transactions |
| 2020 | San Diego Padres, Seattle Mariners | 128 | 2.042 | From transactions |
| 2021 | San Diego Padres, Miami Marlins | 171 | 3.041 | 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.
