| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2010 | Boston Red Sox | 45 | 0.045 | From transactions |
| 2011 | Boston Red Sox, Kansas City Royals | 62 | 0.107 | From transactions |
| 2012 | Pittsburgh Pirates | 70 | 1.005 | From transactions |
| 2013 | Baltimore Orioles | 16 | 1.021 | 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.
