Prospect catalysts

What happened to whom, with the evidence behind each entry. A promotion, a call-up or a measured step change is a reason to look; whether the card market has already repriced it is answered under each row, and “insufficient evidence” is a real answer.

VERIFIED0 REPORTED0 DERIVED2351 UNVERIFIED0

Verified is official or primary evidence. Reported is a named source we have not independently verified. Derived is computed by us from official structured data — a level change between stat lines, or a step change between our own snapshots — and carries no date of its own. Unverified is shown and never relied on.

What happened
Promoted Low-A → Double-A. Level changed between his 2025 and 2026 stat lines (MLB Stats API, official). The date of the move is not recorded here.
Why it matters
A promotion is the club's own read of the player, and the level a card was made at is the level the hobby prices it against. Each rung up is a re-rating event.
What changed in the thesis
Thesis intact — baseball momentum 41/100 — tracking the thesis.
Has the card market responded?
Cannot say: card-price momentum is unmeasured — no earlier observation of the same benchmark series to difference against. No sold evidence means no market response to read, and a listing's asking price is not one.
What to watch next
Whether the strikeout and walk rates hold at the new level over a real sample — the first 100 plate appearances say little.

Why it matters
What happened
Promoted Double-A → Triple-A. Level changed between his 2025 and 2026 stat lines (MLB Stats API, official). The date of the move is not recorded here.
Why it matters
A promotion is the club's own read of the player, and the level a card was made at is the level the hobby prices it against. Each rung up is a re-rating event.
What changed in the thesis
Thesis improving — baseball momentum 77/100 — ahead of the thesis.
Has the card market responded?
Cannot say: card-price momentum is unmeasured — no earlier observation of the same benchmark series to difference against. No sold evidence means no market response to read, and a listing's asking price is not one.
What to watch next
Whether the strikeout and walk rates hold at the new level over a real sample — the first 100 plate appearances say little.
