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 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.

The Bureau on George Kirby
The scouting press, in their own words
George Kirby is just "mid" now... We're now over 250 innings of a 4.20 ERA and 1.28 WHIP with a middling strikeout rate since the start of 2025. He's more in the SP 40-60 range IMO. https://t.co/H1OFMYAe3C
