49 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
30 cards of his are listed and nothing comparable has verifiably sold, so we will not tell you whether the asks are fair.
Closest of his is Jhon Diaz 2020 Bowman Chrome 1st Auto… at $6.99. Waiting on sales.
Our take
Fringe prospect, untested market.
Jhon Diaz scores 49 out of 100 (#2096 of the 7,922 we score), and the case rests on one thing: young for the level — +1.0y vs his level at Double-A — younger than 80% of the players there.
Nothing of his has verifiably sold in 90 days and there is no benchmark price, so we will not tell you what his cards are worth.
Cards of his are listed and none of them can be priced against a confirmed sale, so any judgment about value today would be a guess dressed as a number.
The thing most likely to be wrong here: nothing has sold — no confirmed sale of any card of his in 90 days, so nothing on this page can tell you what a fair price is.
The signal
Young for the level
+1.0y vs his level at Double-A — younger than 80% of the players there.
Contact: below average
31.2% K — strikeout rate, inverted — lower means more bat-to-ball
OPS slipping
.588 last season to .567 this one.
Moved up and held it
High-A to Double-A.
Premium position
CF — the bat does not have to carry the whole profile.
What the hobby pays up for
CF is a position the hobby pays up for.
Why now
No catalyst right now — no promotion, no logged step change, and no measurable move in his card prices. This is a valuation-driven watch rather than a timing one.
What could go wrong
Nothing has sold
No confirmed sale of any card of his in 90 days, so nothing on this page can tell you what a fair price is.
Benchmark not checklist-verified
His core card was identified from how sellers describe it, not from a checklist. The identity is likely, not established.
What the hobby pays for him
Benchmark card: 2020 Bowman Chrome 1st Auto — raw, base, unnumbered.
Described by 4 independent sellers — observed, not checklist-verified.
No price on this card yet
sales exist for this player, none on the benchmark card 4 copies are listed right now — asking prices are supply, never evidence of what it sells for.
This is his benchmark, not the value of any particular card in front of you — a /250 is a different market.
The card that matters
A card-quality answer, not a price one. It does not change when a seller changes their mind.
2020 Bowman Chrome 1st Auto
Raw base 1st Bowman Chrome Auto
The canonical prospect vehicle — every player who has one is compared on it. Identified from 4 independent sellers describing it — likely, not established.
A card is never the one to own because it is numbered. Scarcity is a modifier on a vehicle, not a vehicle — a /25 of a card nobody collects is a rarer version of nothing.
Best value right now
Where the money would go today, which is frequently a lesser card than the one above — or nowhere.
Insufficient market evidence
No live ask and no confirmed sale on any version of his cards, so there is nothing here to call good or bad value.
What would make this a buy

What is for sale right now
30 cards of his are listed · 0 of the 30 we can judge clear the investment bar. These are the 6 worth looking at, best first; the other 24 are under "The whole live market".

What he is good at
skills overall 47 / 80
On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 496 hitters at Double-A — measured against real players at the same level right now — not a scout's projection of what he becomes.

years younger than the median player at his level — positive is young for the level
The overall figure averages the 4 skill rows only. The box-score row and the age row are shown but deliberately left out of it — one is the result those skills produced, and the other is not a skill at all.
The argument
skills at the 38th percentile of the cohort, production at the 18th — his tools run further ahead of his results than 80% of the players he is measured against.
The market prices the stat line, and his is behind what he is doing. That is where a card is cheap for a reason that can change.
How this is read: his skills average 38 and his production sits at 18, a gap of +20. That gap on its own means little — an average of several percentiles always sits nearer the middle than a single one — so it is ranked against the same figure computed the same way for the 496 players at his level we hold a full profile for, where it lands at the 80th percentile.
Will he get there?
Long shot 4.9 / 10

This is an ordering score, not a percentage. We hold no outcome data and have run no backtest, so “a 93% chance of reaching the majors” would be a number we made up and you then spent money on. Built on 100% of what it wants to know.

What his cards have sold forno completed sales logged yet
Real completed sales only — nothing here is an estimate. These come from the scan: it asks eBay about listings it has already seen, and one that ends at a fixed price is recorded as a sale. That builds up over days. You can add one by hand below if you happen to know it, but you are not meant to be the price database.
No sales logged yet. We need at least two to draw a line, and about five spread over a month before the numbers mean much. Add sales you find using the button below.

What this page is missing1 thing we do not hold for him
What this page is missing
Everything above is built from what we actually hold. These are the gaps, so you know which parts of the argument are thin rather than wondering why a panel is quiet.
- We do not have a sold price in 90 days — add one and the whole price side fills in.
Worth reading for this player
- Parallel scarcity calculator — numbered parallels of his cards are in play, and print run drives the premium
- Best Offer calculator — at least one of his live listings accepts offers
- Certified vs aftermarket autographs — signed cards of his are listed, and the two kinds are not worth the same
- Parallels and print runs — his market includes numbered parallels, which are priced off the print run
