What he’s paid
Pre-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
- $0.53Mest
- Tax hit
- $0.53M
- Service time
- 0 yr 34 d
- Options left

The deal 1 year (2026)
On the sheet: 1 y (26)
Regime read from his service time, not from the sheet — it does not project him past this season. Super Two eligibility is the top 22% of a class and can move this line in a way service time alone cannot see.
Cash and the tax hit are two different rulebooks and are never subtracted from one another — see the payroll board for his club, Athletics.

What the sheet prices each season at
| Season | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 |
|---|---|---|---|---|---|---|---|
| Salary | Minimum | Minimum | Minimum | Minimum | Arb 1 | Arb 2 | Arb 3 |
A base salary under his own reading, and never subtracted from the cash figure above: a signing bonus lands in one and not the other, so the two disagree on most men without either being wrong. And the sheet does not mark which future seasons are GUARANTEED — a club option and a projected arbitration award are both just a number here, so read past the end of the deal as his forecast rather than as money owed.
The tax AAV above is his number under the CBA’s own rulebook, not the average we work out from Cot’s total. On a contract with deferred money the two come apart on purpose — and neither is subtracted from the other.
