What he’s paid
ArbitrationA market fact, not an engine read: what a club decided about him, on the season before this one. Figures from Cot’s, as of .
- 2026 salary
- $0.24M
- Tax hit
- $0.24M
- Service time
- 7 yr 150 d
- Guaranteed
- $13M
The deal 2 years $13M (2025–2026) — $6.5M a year on average, worked out by us rather than stated on the sheet, and not the same thing as the tax hit above
On the sheet: 2 y/$13M (25-26) · agent O'Connell Sports · 1 / 3 options left
After this season, as the sheet has it
| Season | 2027 |
|---|---|
| Cash | Free agent |
| Tax hit | — |
Regime flagged: the sheet's out-year codes read arbitration and 7.150 reads free_agency. Kept the sheet's; Super Two and optional assignments move this line and the service boundary cannot see them.
Cash and the tax hit are two different rulebooks and are never subtracted from one another — see the payroll board for his club, Kansas City Royals.
