Last with Los Angeles Dodgers · CF · No longer on a 40-man roster
Alek Thomas has an estimated 3 years and 157 days of major league service time — 3.157 in the notation clubs use, from 673 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2022 | Arizona Diamondbacks | 141 | 0.141 | From transactions |
| 2023 | Arizona Diamondbacks | 154 | 1.123 | From transactions |
| 2024 | Arizona Diamondbacks | 152 | 2.103 | From transactions |
| 2025 | Arizona Diamondbacks | 172 | 3.103 | From transactions |
| 2026 | Arizona Diamondbacks, Los Angeles Dodgers | 54 | 3.157 | 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.
