San Francisco Giants prospects

275 tracked players across 8 affiliates (ACL Giants, DSL Giants Black, DSL Giants Orange, Eugene Emeralds, Richmond Flying Squirrels, Sacramento River Cats, San Francisco Giants, San Jose Giants). 190 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.

Measured improvement while young for the level or freshly promoted, on a rated player.

Youngest for level

6View all

Two or more years younger than the typical player at the level. Context, not a quality claim.

Latest promotions

At a higher level this season than last, from the two official stat lines. Dates live in the catalyst tracker.

Highest player quality

6The club on the player board

Our all-round read on the player. Nothing in this list is a card price.

Baseball up, cards flat

0View all

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: Ramon Marquez, Argenis Cayama, Diego Velasquez, Jonah Cox, Jose Astudillo, Scott Bandura.

  1. DERIVEDPromoted Rookie → High-Adate not recorded
    Jhonny Level

    High-ASan Francisco Giants

    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 → 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 improving — baseball momentum 69/100 — 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.
