Left of the rule is the league’s own line on the player — his results, not our numbers, and never an input to any FVR signal. Right of it is what the engine measures.

What they pay
A market fact, not an engine read — and the club’s own row from the payroll board, computed once so the two pages cannot disagree.

PROPOSED Below the floor the owners proposed on 2026-07-21 — this club would have to spend up. A proposal out of a negotiation that has not happened, not a rule. The line in force is the $244M tax threshold above.
The five biggest commitments this season
- Josh Naylor$17.3M
- Logan Gilbert$16.4M
- Cal Raleigh$13.7M
- George Kirby$10.6M
- Seranthony Domínguez$10.0M
Cash is what the club pays out; the tax payroll is average annual values under the CBA’s own rulebook. Two answers to one question, never subtracted from one another. Figures from Cot’s.
A second set of books
The numbers above are Cot’s. These are MLB Spreadsheets’s, and they answer two questions Cot’s cannot: what this payroll is made of, and where it has moved since Opening Day. We keep both sources rather than merging them, because the only thing that catches an error in one is the other.
Where the two sources disagree
- On cash payroll, Cot’s reads $130.6M and MLB Spreadsheets reads $170.4M — $39.8M apart.
- On tax payroll, Cot’s reads $162.3M and MLB Spreadsheets reads $204.4M — $42.1M apart.
Both are reputable and neither is wrong on its own terms. A gap on sheets a month apart is one source catching up; a gap on sheets a few days apart is a real disagreement about what a club is paying, and nobody prints those. We do not average them, and every figure on this site says which source it came from.
- Cash payroll
- $163.0M → $170.4M +$7.4M
- Tax payroll
- $186.3M → $204.4M +$18.2M
A move is not a verdict. Adding payroll is not virtue and cutting it is not vice, so nothing here is colored — the sign is the whole fact. And a move in dollars is not a payroll in dollars: we never compare one to the other.
Cash payroll
$170.4M
Tax payroll
$204.4M
The bar divides the $204.7M this club pays out. It takes $0.3M back in — adjustments and credits — which is what brings the tax payroll to $204.4M.

| Total | $170.4M | $204.4M |
An em dash in one column and a figure in the other is not a missing number — it is the two rulebooks sorting the same money differently. A prorated signing bonus is in the cash figure and already inside the average annual value the tax is assessed on; league charges are the reverse. That is why the two totals differ, and why they are never subtracted from one another.
Composition and Opening Day figures from Ethan Hullihen (@EthanHullihen, MLBSpreadsheets), from a workbook whose oldest relevant sheet is dated . The workbook carries a different date on every tab, so this is the oldest of the ones we read rather than the file’s own. Every line above was checked to sum to the club’s stated total before it was printed.
