Athletics prospects
229 tracked players across 6 affiliates (ACL Athletics, DSL Athletics, Lansing Lugnuts, Las Vegas Aviators, Midland RockHounds, Stockton Ports). 171 have a real stat line or market evidence behind them. Everything below is measured; a module with nothing measured says so.
Trajectory changes from two seasons of official stat lines, ranked by size and credibility, then by quality. Not a hot week.

The development has moved further than the price of the benchmark card. Needs sold evidence on the card side, which most prospects do not have.
No measured lag on this club. 6 players are up strongly with no readable card market yet — waiting for market evidence, not lagging it.
Waiting: Henry Bolte, Brayan Buelvas, Joshua Kuroda-Grauer, Steven Echavarria, Ali Camarillo, Cole Conn.
Promotions, step changes and logged events on this club, each with its evidence grade.

Why it matters
- What happened
- Promoted Low-A → High-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 61/100 — 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.
