60 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
13 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 Kala'i Rosario 2020 1st Bowman Chrome AUTO… at $84.97. Waiting on sales.
Our take
Solid prospect, untested market.
Kala'i Rosario scores 60 out of 100 (#770 of the 7,922 we score), and the case rests on one thing: young for the level — +2.0y vs his level at Triple-A — younger than 87% 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: small sample — 85 PA this season — too few to read a rate stat off with any confidence.
The signal
Young for the level
+2.0y vs his level at Triple-A — younger than 87% of the players there.
Contact: well below
31.8% K — strikeout rate, inverted — lower means more bat-to-ball
OPS slipping
.845 last season to .797 this one.
Power slipping
.231 last season to .162 this one.
Plate discipline: above average
11.8% BB — walk rate — higher means he makes pitchers come to him Better than 60% at his level.
Moved up and held it
Double-A to Triple-A.
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
Small sample
85 PA this season — too few to read a rate stat off with any confidence.
Swing-and-miss
Contact grades 39 on the 20–80 scale (31.8% K). strikeout rate, inverted — lower means more bat-to-ball
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.
Modeled value only
The fair values shown for his live cards are arithmetic from related evidence, not confirmed sales of the exact card.
What the hobby pays for him
A benchmark is the one standardized card we track a player's market on, so every player's price means the same thing.
Benchmark not yet established — no 1st Bowman vehicle observed for this player. Until one exists, only his individual listings can be judged.
The card that matters
A card-quality answer, not a price one. It does not change when a seller changes their mind.
Canonical card not established — We have not assigned him a benchmark card yet, so there is no canonical answer to give. Until one exists, only his individual listings can be judged.
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
Nothing of his has confirmed sold, so there is no value to measure against. Among the asks alone, /99 at $23.64 costs 1.36× base, and print run alone suggests 1.80×, with no measured sales to check it against — best balance available. That is a comparison of sellers, not evidence of what these are worth, and it rests on the print-run assumption rather than measured premiums.

On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 728 hitters at Triple-A — measured against real players at the same level right now — not a scout's projection of what he becomes.

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 43th percentile of the cohort, production at the 62th — his results run further ahead of his tools than 80% of the players he is measured against.
The stat line is doing the selling and the skills underneath it are not carrying it. Pay for the line and you are paying for the part that does not repeat.
How this is read: his skills average 43 and his production sits at 62, a gap of -19. 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 726 players at his level we hold a full profile for, where it lands at the 20th percentile.
Will he get there?
Real chance 6.8 / 10
- already at Triple-A
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 86% of what it wants to know — missing production.

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.
