| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2015 | New York Mets | 172 | 1.000 | From transactions |
| 2016 | New York Mets | 53 | 1.053 | From transactions |
| 2017 | New York Mets | 16 | 1.069 | From transactions |
| 2018 | Baltimore Orioles | 52 | 1.121 | From transactions |
| 2019 | Baltimore Orioles | 5 | 1.126 | From transactions |
| 2020 | Tampa Bay Rays | 14 | 1.140 | 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.
