| 2009 | San Francisco Giants | 47 | 0.047 | From transactions |
| 2010 | San Francisco Giants | 0 | 0.047 | From transactions |
| 2011 | San Diego Padres | 105 | 0.152 | From transactions |
| 2012 | San Diego Padres | 172 | 1.152 | Carried forward |
| 2013 | San Diego Padres | 172 | 2.152 | From transactions |
| 2014 | Houston Astros | 172 | 3.152 | 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.
