Scout’s note

George Klassen owns one of the best seasons in the sport — 24 strikeouts in 27 major-league innings, a 3.67 ERA — and our Index still lists him ungraded. The stuff model is stability-tested but not outcome-validated, so no big-league arm gets a board flag from it. The ERA-FIP luck gap did clear the bar, though, and that call is filed by hand. A sixth-rounder from West Bend, Wisconsin, debuted this April; the board grade waits for the science.

Current signals

The read: Klassen is in the Index ungraded, on purpose: our stuff model is stability-tested but not outcome-validated, so no big-league arm gets a board flag from it — not even one of the best seasons in the sport. (Calls are another matter: the ERA-FIP luck gap did clear the bar, and we file arm regression calls by hand from it.) The page is here because the player matters; the board grade waits for the science.

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.
