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

| 2019 | Cincinnati Reds | 172 | 1.009 | From transactions |
| 2020 | Cincinnati Reds | 69 | 1.078 | From transactions |
| 2021 | Cincinnati Reds | 171 | 2.077 | 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.
