Scout’s note
WAR of 1.8 across 317 games is the engine's read on Gelof — he sits on the ledger, tracked but not flagged, meaning his contact quality hasn't broken from his results enough to price. The 2021 second-round pick from Rehoboth Beach is 26 now, and this season's .258 with 14 home runs in 80 games outpaces his career .233. The pushback is live, though: .188 over his last 13, with 15 strikeouts in that span.

What the sheet prices each season at
| Season | 2026 | 2027 | 2028 | 2029 |
|---|---|---|---|---|
| Salary | 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.
