Last with Detroit Tigers · P · No longer on a 40-man roster
Fu-Te Ni has an estimated 1 year and 17 days of major league service time — 1.017 in the notation clubs use, from 189 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2009 | Detroit Tigers | 101 | 0.101 | From transactions |
| 2010 | Detroit Tigers | 88 | 1.017 | 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
