61 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
21 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 2025 Bowman Chrome Prospect Teilon Serrano…. Priced above value.
Our take
Solid prospect, untested market.
Teilon Serrano scores 61 out of 100 (#706 of the 7,922 we score), and the case rests on one thing: young for the level — +1.0y vs his level at Rookie — younger than 80% of the players there.
His core Bowman card has been selling at $1–4 off 2 confirmed sales.
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: swing-and-miss — contact grades 41 on the 20–80 scale (30.4% K). strikeout rate, inverted — lower means more bat-to-ball
The signal
Young for the level
+1.0y vs his level at Rookie — younger than 80% of the players there.
Contact: well below
30.4% K — strikeout rate, inverted — lower means more bat-to-ball
The case is fading
Baseball momentum 0/100 — the on-field case is fading. Read from his baseball alone — never from what his cards did.
Plate discipline: plus-plus
27.3% BB — walk rate — higher means he makes pitchers come to him Better than 96% at his level.
Premium position
CF — the bat does not have to carry the whole profile.
Power: plus
.187 ISO — isolated power — slugging minus batting average, so hits that go for extra bases Better than 85% at his level.
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
Swing-and-miss
Contact grades 41 on the 20–80 scale (30.4% K). strikeout rate, inverted — lower means more bat-to-ball

The card that matters
A card-quality answer, not a price one. It does not change when a seller changes their mind.
2025 Bowman Chrome 1st Auto CPA-TS
Raw base 1st Bowman Chrome Auto
The canonical prospect vehicle — every player who has one is compared on it. Identified from 12 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.
No good entry today
The closest to fair is Teilon Serrano 2025 Bowman Chrome 1st Prospect Auto #CPA-TS Twins (BT) at $18.49, 1149% over the $1.48–3.50 that copies of it have confirmed sold in. Nothing of his is currently below its own sold band.
That card at or under $1.48 delivered would be at the bottom of what it has actually sold for.
What would make this a buy
- Priced above value
- Player not there yet
- On his best-priced card: waiting on sales.

What he is good at
skills overall 56 / 80
On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 1087 hitters at Rookie — measured against real players at the same level right now — not a scout's projection of what he becomes.

+1.0y vs his level
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 68th percentile of the cohort, production at the 75th — the gap between the two is ordinary for this level.
Nothing to arbitrage here: he is producing about what his skills say he should. Judge the card on price and the player on the grades.
How this is read: his skills average 68 and his production sits at 75, a gap of -7. 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 1,087 players at his level we hold a full profile for, where it lands at the 39th percentile.
Will he get there?
Real chance 5.2 / 10
- hitting well — 0.844 OPS in 194 PA (not ranked against his level)
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 82% of what it wants to know — missing readiness.

What his cards have sold for1 logged sale
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.
Only 1 sale logged so far. 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.
