| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2006 | Seattle Mariners | 156 | 0.156 | From transactions |
| 2007 | Seattle Mariners | 172 | 1.156 | Carried forward |
| 2008 | Seattle Mariners | 172 | 2.156 | Carried forward |
| 2009 | New York Mets | 172 | 3.156 | Carried forward |
| 2010 | New York Mets | 158 | 4.142 | From transactions |
| 2011 | Milwaukee Brewers | 35 | 5.005 | 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.
