Blowout Cards, a major trading card retailer, said it will pay $5,000 to the Phillies fan who took a Harrison Bader home-run ball away from a 10-year-old boy after yelling at his father in the stands during Friday night’s 9-3 win over the Marlins.

“But there is a catch,” the company said the next day in a proposal on its website.

“We want that ball signed and inscribed by her — and only her, whoever she is — ‘I’m sorry’ so we can simply give it back to the kid. Our offer is official and the offer is firm.”

The woman’s identity remains unknown.

Blowout Cards also posted the offer on X.

The story garnered national attention after a video of the woman berating the father in the left-field stands in Miami made the rounds on social media Friday night.

Bader’s home run ball flew into the seats and bounced around as fans scurried for it — with the father, later identified as Drew Feltwell by NBC10 Philadelphia, retrieving it.

He placed the ball in his son’s glove and hugged him before the woman approached him and began pointing in his face, as seen in the clip.

Feltwell eventually took the ball from his son’s glove and gave it to the woman, who took it and walked away.

Feltwell told NBC10 he attended the game with his family for his son Lincoln’s 10th birthday.

“That was what we were there for,” Feltwell said. “We were there to get a home run ball. I thought I had accomplished this great thing and putting [it] in his glove meant a lot and she was just so adamant and loud and yelling and persistent and I just didn’t want to deal with it anymore.”

The Marlins did right by the family.

An employee delivered a gift bag, and an apology, to Lincoln in the immediate aftermath of the ball snatching, as seen in a video on social media.

After the game, the Phillies brought Lincoln into the locker room, where he got a signed bat from Bader.

“Going home with a signed bat from Bader,” the team’s official X account wrote, including a photo of centerfielder meeting Lincoln and his family.

The incident elicited responses from all over.

Marcus Lemonis — CEO of Camping World, best known as the host of the CNBC reality series “The Profit” — offered to send the boy and his family to the World Series

“Oh and you just won an RV as well,” Lemonis added in an X post.
