Last with Cincinnati Reds · CF · No longer on a 40-man roster
Michael Siani has an estimated 1 year and 72 days of major league service time — 1.072 in the notation clubs use, from 244 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2022 | Cincinnati Reds | 15 | 0.015 | From transactions |
| 2023 | Cincinnati Reds, St. Louis Cardinals | 18 | 0.033 | From transactions |
| 2024 | St. Louis Cardinals | 172 | 1.033 | From transactions |
| 2025 | St. Louis Cardinals | 37 | 1.070 | From transactions |
| 2026 | Baltimore Orioles | 2 | 1.072 | 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.
