Last with Texas Rangers · P · No longer on a 40-man roster
Kohei Arihara has an estimated 1 year and 23 days of major league service time — 1.023 in the notation clubs use, from 195 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2021 | Texas Rangers | 169 | 0.169 | From transactions |
| 2022 | Texas Rangers | 26 | 1.023 | 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.
This figure is an estimate reconstructed from public roster
transaction records. It is not an official MLB or MLBPA figure — those are
