New York Yankees · P · Pre-arbitration
Brent Headrick has an estimated 1 year and 158 days of major league service time — 1.158 in the notation clubs use, from 330 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2023 | Minnesota Twins | 49 | 0.049 | From transactions |
| 2024 | Minnesota Twins | 4 | 0.053 | From transactions |
| 2025 | New York Yankees | 105 | 0.158 | From transactions |
| 2026 | New York Yankees | 172 | 1.158 | 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.
