Former MLB pitcher Noah Syndergaard is mentioned in podcaster Sofia Franklyn’s explosive memoir, “Daddy Issues,” which unpacks her infamous fallout — personally and professionally — with his ex, Alex Cooper.

Franklyn and Cooper were best friends and roommates when they started the “Call Her Daddy” podcast with Barstool Sports, which became a cash cow for the company. The pair went their separate ways after a high profile contract dispute with Barstool in 2020 — and Cooper got the “Call Her Daddy” podcast, and Franklyn started her own podcast, “Sofia with an F.”

In the book — which releases Wednesday and tells Franklyn’s perspective of the situation — Franklyn says Cooper asked her to secretly snap a photo of Cooper and Syndergaard out to dinner together and she did, according to TMZ.

Franklyn claims Cooper told her that Syndergaard was “such a s–t” and that she wanted the photos to send to his mom if she needed to.

When the pics surfaced on a sports website in January 2018, Franklyn suggests Cooper leaked the images to the website, adding that only she and Cooper had access to the photos.

Syndergaard, playing for the Mets at the time, and Cooper began dating in April 2017, when they were spotted kissing at a Knicks game, as reported by The Post.

After an on-off relationship, Syndergaard appeared to indicate he was single in a post on Twitter, now X, in December 2017, which read: “Baseball is my significant other” with the hashtag, “focus.”

Cooper reflected on the relationship in an interview with Rolling Stone published in September 2023.

“I was living this very glamorous lifestyle because he was rich,” she said. “And I was nobody.” 

Cooper married film producer Matt Kaplan, a former quarterback at Columbia University, in April 2024, and gave birth to their first child last month.

Syndergaard, now 34, last played in the majors with the Cleveland Guardians before his release in August 2023.

He was released by the Chicago White Sox in August 2025 following a minor league stint.

During a May appearance on OutKick’s “Tomi Lahren is Fearless,” Syndergaard said he was in a relationship that he preferred to “keep under wraps.”

At the time, Lahren asked him about Cooper and a remark she made about him — saying he “Can’t get a f–king contract” — while on her “Call Her Daddy” podcast in 2023.

“I haven’t spoken to her in eight years or so,” Syndergaard said. “So, I guess I continue to live rent-free in her head. I don’t really know.”
