| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2014 | Texas Rangers | 84 | 0.084 | From transactions |
| 2015 | Oakland Athletics, Texas Rangers | 134 | 1.046 | From transactions |
| 2016 | Oakland Athletics | 136 | 2.010 | From transactions |
| 2017 | Oakland Athletics | 172 | 3.010 | From transactions |
| 2018 | Oakland Athletics | 118 | 3.128 | 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.
