Public buyer warning

BUYER BEWARE: ALEX DIAZ (@BALLPARK_ALEX) — FRAUDULENT ACTIVITY EXPOSED

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

The Story

A self-appointed champion of "trust and transparency" sold 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 what made the listing convincing. His listing photos showed a flawless card. What arrived had a soft, whitened corner no honest photo could have hidden.

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

The full story

What happened, in detail

Dates and quotes below are taken from the message thread between the buyer and the seller, August 2026.Every original screenshot is published here.

Mid-August 2026 · The listing

The card was a 2026 Topps Finest Shohei Ohtani “The Man” SSP #TM-2, listed on Facebook Marketplace at $1,750 by “Alex Diaz” — a seller profile carrying 4.9 stars and 37 reviews. The listing photos showed a card in perfect condition: sharp corners, clean edges, a flawless surface.

Before agreeing to anything, the buyer asked the one question that matters on a raw card: did it have any noticeable damage? The answer was unambiguous. “No, it's real clean. I got it in a break.”

The deal · $1,200 by Zelle

They agreed on $1,200. Payment went by Zelle to a recipient registered as “Alexis Diaz.” Because Zelle caps what can be sent to a new recipient, the money went across in three separate transfers — $500, then $500, then $200 — over more than one day.

Zelle is the detail worth pausing on. It is a bank-to-bank transfer with no purchase protection and no chargeback: once it clears, there is no dispute button. Marketplace conversations that steer a buyer toward Zelle for a four-figure card are steering them away from every safety net that exists.

Before shipping · The “proof” photos

With the money moving in pieces, the buyer asked for more photos of the actual card. The seller sent close-ups of the front and the back. Neither showed a single flaw.

Those photos do not match the card that arrived. The corner damage that would show up in the buyer's hand a week later is nowhere in them.

August 16–22 · The shipping saga

A tracking number was provided. It did not move. Days passed with no scan, no pickup, and no confirmation that anything had actually been handed to a carrier.

Asked for a drop-off receipt, the seller said there wasn't one: it was all electronic. Pressed again later, the story changed — now he had proof of drop off. Both statements cannot be true.

Somewhere in the middle of this, while the buyer was still asking where a $1,200 card was, the buyer asked about a second card and the seller responded.

His reassurance through all of it was the same line: “You will get that card.” And his defense, when doubted, was his own reach — “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.”

On arrival · The card that showed up

The card finally arrived. The bottom-right corner is soft and whitened — visible in hand immediately, and obvious in a close-up. It is not the corner in the listing photos, and it is not the corner in the “proof” photos.

Checking the image files he had sent, the metadata had been stripped. The listing images carried the flat, over-smoothed look of AI clean-up: perfect edges, a surface with no texture, damage simply gone. When the buyer raised the AI editing directly, the seller never denied it.

The refusal · Deleted and blocked

The buyer offered two ways out, both reasonable: a partial refund to reflect the condition of the card actually received, or a full refund with the card shipped straight back.

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

The Marketplace listing was deleted shortly after. The buyer was blocked. What remains is the record: the listing screenshots, the AI-enhanced photos, the mismatched “proof” photos, the damaged card, and his own messages.

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 the buyer 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.

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. The buyer asked directly about damage: “No, it's real clean. I got it in a break.”

  2. 2

    The deal

    They 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 the buyer asked for extra photos before finishing payment, he sent close-ups showing no damage. They were not of the card they 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 exchange about another card the buyer asked about.

  5. 5

    The arrival

    The card showed up with a soft, whitened bottom-right corner. The buyer 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

    The buyer 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 them.
