Scout’s note
Jonah Heim, a switch-hitting catcher from Buffalo drafted in the fourth round back in 2013, has caught 713 major-league games with a .222 average and 81 home runs. His last 14 days at the MLB level: 3 games, .300, one RBI — a bench role, not a hot streak.

What the sheet prices each season at
| Season | 2026 |
|---|---|
| Salary | $1.3M |
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.
