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.

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.

  1. DERIVEDPromoted Rookie → Low-Adate not recorded
    Berny Ortiz

    Low-ABoston Red Sox

    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
    What happened
    Promoted Rookie → Low-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
    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 Rookie → Low-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.
