| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2012 | Milwaukee Brewers | 70 | 0.070 | From transactions |
| 2013 | Milwaukee Brewers | 172 | 1.070 | From transactions |
| 2014 | Milwaukee Brewers | 172 | 2.070 | From transactions |
| 2015 | Milwaukee Brewers, New York Mets | 38 | 2.108 | From transactions |
| 2016 | New York Mets | 172 | 3.108 | 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.
