Scout’s note
Zack Gelof carries a 2.7 MLB WAR and is hitting .256 with an .797 OPS and 22 home runs across 111 games for the Athletics this season. The 26-year-old from Rehoboth Beach, a second-round pick in 2021, has been locked in of late — a .360 average and 1.208 OPS with three homers over his last seven MLB games. With 56 career steals and 55 career home runs across 348 games, the ledger reads as a player finding his footing in his fourth major-league season.

|---|---|---|---|---|
| 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.
