Last with New York Yankees · P · No longer on a 40-man roster
Matt Krook has an estimated 60 days of major league service time — 0.060 in the notation clubs use, from 60 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2023 | New York Yankees | 24 | 0.024 | From transactions |
| 2024 | Baltimore Orioles | 3 | 0.027 | From transactions |
| 2025 | Oakland Athletics | 6 | 0.033 | From transactions |
| 2026 | Washington Nationals, Oakland Athletics | 27 | 0.060 | 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.
