Arizona Diamondbacks · P · Pre-arbitration
Cristian Mena has an estimated 1 year and 125 days of major league service time — 1.125 in the notation clubs use, from 297 days credited on a major league roster.
| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2024 | Arizona Diamondbacks | 1 | 0.001 | From transactions |
| 2025 | Arizona Diamondbacks | 124 | 0.125 | From transactions |
| 2026 | Arizona Diamondbacks | 172 | 1.125 | 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.
