Last with Houston Astros · P · No longer on a 40-man roster
Brett Oberholtzer has an estimated 2 years and 138 days of major league service time — 2.138 in the notation clubs use, from 482 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2013 | Houston Astros | 83 | 0.083 | From transactions |
| 2014 | Houston Astros | 141 | 1.052 | From transactions |
| 2015 | Houston Astros | 86 | 1.138 | From transactions |
| 2016 | Los Angeles Angels, Philadelphia Phillies | 172 | 2.138 | 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.
