| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2013 | Chicago White Sox | 28 | 0.028 | From transactions |
| 2014 | Chicago White Sox | 36 | 0.064 | From transactions |
| 2015 | Chicago White Sox | 34 | 0.098 | From transactions |
| 2016 | San Diego Padres, Chicago White Sox | 122 | 1.048 | 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.
