Last with Tampa Bay Rays · P · No longer on a 40-man roster
Ryan Garton has an estimated 157 days of major league service time — 0.157 in the notation clubs use, from 157 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2016 | Tampa Bay Rays | 97 | 0.097 | From transactions |
| 2017 | Seattle Mariners, Tampa Bay Rays | 56 | 0.153 | From transactions |
| 2018 | Seattle Mariners | 0 | 0.153 | From transactions |
| 2019 | Seattle Mariners | 4 | 0.157 | 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.
