| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2012 | Milwaukee Brewers | 172 | 1.000 | From transactions |
| 2013 | Milwaukee Brewers | 172 | 2.000 | From transactions |
| 2014 | Kansas City Royals | 172 | 3.000 | From transactions |
| 2015 | San Francisco Giants | 172 | 4.000 | From transactions |
| 2016 | Seattle Mariners | 147 | 4.147 | From transactions |
| 2017 | Houston Astros, New York Mets, Toronto Blue Jays | 172 | 5.147 | 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.
