| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2009 | Oakland Athletics | 19 | 0.019 | From transactions |
| 2010 | Oakland Athletics | 91 | 0.110 | From transactions |
| 2011 | Minnesota Twins | 0 | 0.110 | From transactions |
| 2012 | Minnesota Twins | 41 | 0.151 | From transactions |
| 2013 | Cleveland Indians | 34 | 1.013 | 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.
