| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2014 | Baltimore Orioles | 145 | 0.145 | From transactions |
| 2015 | Baltimore Orioles | 172 | 1.145 | Carried forward |
| 2016 | Baltimore Orioles | 172 | 2.145 | From transactions |
| 2017 | Baltimore Orioles | 172 | 3.145 | Carried forward |
| 2018 | Baltimore Orioles | 154 | 4.127 | From transactions |
| 2019 | Arizona Diamondbacks | 67 | 5.022 | From transactions |
| 2020 | Toronto Blue Jays | 139 | 5.161 | 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.
