Public buyer warning

BALLPARK_ALEX IS A SCAMMER

He sold me a $1,200 Shohei Ohtani card advertised as perfectly clean. The listing photos were AI-enhanced. The card arrived with a damaged corner. When I asked him to make it right, he told me to do my worst — and blocked me.

The Story

A self-appointed champion of "trust and transparency" sold me an AI-“restored” card and never mentioned the damage

Ballpark_alex — Alex Diaz of Miami, Florida — is a familiar name to a lot of collectors: 17,000 Instagram followers, a seat on the CTCA Advisory Board, and a published column series about trust in the hobby. That reputation is exactly what made this work. His listing photos showed a flawless card. What arrived had a soft, whitened corner no honest photo could have hidden.

When I confronted him with the evidence — including metadata stripped from his own images — he never denied it. He refused every resolution, deleted the listing, and blocked me.

Is ballpark_alex a scammer?

The hypocrisy

The “Trust Guy” who wrote the book on it

Alex Diaz sits on the advisory board of the CTCA and co-authors its Collector Trust Series — a column teaching collectors about transparency, disclosure, and accountability. Here are his own published words, next to what he actually did.

“Trust me, the card is clean… But trust isn't something that should be demanded. It's something that's earned.”

His article: “Trust Should Never Require Blind Faith” — thectca.org/trust

What he did: Sold a damaged card as “real clean,” then demanded I trust him when the tracking went dark.

“Transparency is only half the equation. The other half is accountability.”

His article: “Who Is Accountable?” — thectca.org/trust

What he did: Refused a partial refund. Refused a full refund with the card returned. Accepted zero accountability.

“Trust is built when something goes wrong.”

His article: “Trust Is Earned in the Dark” — thectca.org/trust

What he did: When something went wrong, he deleted the listing and blocked the buyer.

Disclosure shouldn't be optional.

His article: “Disclosure Shouldn't Be Optional” — thectca.org/trust

What he did: Used AI-enhanced photos that hid the damage, and disclosed nothing.

The record

In his own words

Transcribed from the seller's messages, dated, from the buyer's records. Original screenshots on file.

“No, it's real clean. I got it in a break.”

Asked directly whether the card had any noticeable damage — before the sale.

“You will get that card.”

After days of no tracking movement, no drop-off receipt, and rising doubts.

“Why in the f--- would someone that is deep in the card world and has as many followers as I have try to f--- anyone over with cards man? Think about it.”

His defense: his follower count.

“…now I don't give a s---. Do your worst kid. I'll take my chances. Oh and I'm blocking you here also. ✌️”

After being offered a partial refund, or a full refund with the card returned.

The receipts

The evidence

Undisclosed damage

Three sets of images tell the whole story: what was advertised, what he sent as “proof,” and what actually arrived in the mail.

1 · What was advertised — the AI-enhanced listing photos

AI-enhanced listing photo from Ballpark Alex — Ohtani card front, damage edited out
Listing photo, front. Corners razor-sharp, surface flawless. This image was AI-enhanced; the real corner damage is edited out.
AI-enhanced listing photo from ballpark_alex — Ohtani card back
Listing photo, back. Studio-perfect render — no wear anywhere.

2 · What he sent as “proof” — photos that weren't of my card

“Proof” photo Ballpark Alex sent — not the card that arrived
Sent when I asked for more photos before paying. No damage visible — because this is not the card I received.
Second “proof” photo from ballpark_alex — card back, no damage shown
Second “proof” photo. Again, no damage. Neither image matches the card that arrived.

3 · What actually arrived — the damaged card

Damaged Ohtani card as received from Ballpark Alex — soft corner
The card as received. The bottom-right corner is soft — clearly not the card in the listing or the “proof” photos.
Close-up of corner whitening on the damaged card ballpark_alex sold as mint
Close-up: whitening and wear on the corner. This damage was never disclosed and was edited out of the listing photos.

The listing itself — deleted after I called him out

What happened

Step by step

  1. 1

    The listing

    A 2026 Topps Finest Shohei Ohtani “The Man” SSP #TM-2, listed at $1,750 with immaculate AI-enhanced photos. I asked directly about damage: “No, it's real clean. I got it in a break.”

  2. 2

    The deal

    We settled on $1,200 over Zelle — recipient registered as “Alexis Diaz.” Zelle's new-recipient limit forced three payments: $500, $500, $200.

  3. 3

    The “proof” photos

    When I asked for extra photos before finishing payment, he sent close-ups showing no damage. They were not of the card I would receive.

  4. 4

    The shipping saga

    Aug 16–22. Days of no tracking movement, no drop-off receipt, shifting stories — “it was all electronic” became “I have proof of drop off” — and a mid-crisis pitch to buy another card.

  5. 5

    The arrival

    The card showed up with a soft, whitened bottom-right corner. I stripped the metadata from his images; the listing photos had been AI-enhanced. The damage was never visible in anything he sent.

  6. 6

    The refusal

    I offered a partial refund, or a full refund with the card returned. His answer: “Do your worst kid. I'll take my chances.” Then he deleted the listing and blocked me.

How to spot an AI-edited card photo

  • Corners and edges that look unnaturally sharp against a soft background
  • Print dots, gloss, and surface texture that vanish under magnification
  • Text or logos on the card that are slightly warped or misspelled
  • Backgrounds, hands, or sleeves that bend or blur where they meet the card
  • A seller who will not send a fresh photo of the card next to today's date
  • A feed full of generated artwork instead of real, in-hand photography
  • Strip the image metadata — AI-processed images leave traces
  • “Trusted” names and follower counts are not a substitute for real photos

Did this happen to you too?

If you bought from Ballpark_alex and something did not add up, send your screenshots. The more documented accounts sit in one place, the harder this is to bury.
