Last with Chicago White Sox · P · No longer on a 40-man roster
Daniel Webb has an estimated 2 years and 146 days of major league service time — 2.146 in the notation clubs use, from 490 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2013 | Chicago White Sox | 28 | 0.028 | From transactions |
| 2014 | Chicago White Sox | 172 | 1.028 | Carried forward |
| 2015 | Chicago White Sox | 131 | 1.159 | From transactions |
| 2016 | Chicago White Sox | 159 | 2.146 | 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.
