What he’s paid
Under contractA 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
- $2.13M
- Tax hit
- $3.30M
- Service time
- 7 yr 131 d
- Guaranteed
- $20M
The deal 2 years $20M (2026–2027) — $10.0M 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/$20M (26-27)+28 m opt · agent Epitome Spts · 1 / 3 options left
After this season, as the sheet has it
| Season | 2027 | 2028 |
|---|---|---|
| Cash | $10.0M | $1.4M |
| Tax hit | $10.8M | — |
Cash and the tax hit are two different rulebooks and are never subtracted from one another — see the payroll board for his club, Seattle Mariners.
A second set of books
The same contract, read by MLB Spreadsheets (Ethan Hullihen), as of . We keep two sources on this because one source cannot check itself.
- Tax AAV
- $10.8M
- Guaranteed
- $20.0M
- Term
- 2 yrs
What the sheet prices each season at
| Season | 2026 | 2027 | 2028 |
|---|---|---|---|
| Salary | $7.0M | $10.0M | $12.0M |
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.
Two sources, read a month apart, put this guarantee at the same dollar. That is the check, and it passed.
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.
