In the first game of the Yankees’ doubleheader Thursday against the Rays, manager Aaron Boone went viral on social media after he unleashed fury on rookie home plate umpire Brennan Miller, prompting an ejection and subsequent suspension.

But the viral video didn’t come from a major television network or any official media outlet.

Insert Jimmy O’Brien, commonly known as “Jomboy,” who was the one-man show behind the enhanced audio that allowed everyone at home to have a front-row seat for Boone’s explicit tirade, caught by the YES Network’s cameras and microphones.

So, who is this Yankees Twitter sensation who has been filling every feed with such entertaining content?

O’Brien was born a Yankees fan despite moving frequently as a child because of his father’s job. He graduated from Central Connecticut State with a degree in history before landing a job as a videographer and video editor. He then attended film school in San Francisco before quitting his job as a wedding videographer in March 2018 to pursue establishing his own company, Jomboy Media.

The “breakdown” videos originated after the Yankees and Tigers brawled in 2017.

“I had the ability to go through the footage frame by frame and I was interested to follow each player and see what they did,” O’Brien told The Post via direct message. “I figured others would find it just as interesting as me so I talked over them and showed them what I had found. From there I kept doing breakdowns for the Yankees.

“This season I pivoted to covering the entire league,” he added. “I can read lips fairly well, and sometimes, like last night, I can pick up the hot mics on the field and put the subtitles on the screen.”

To O’Brien, originality is the most important thing. The production of his breakdown videos is simply pairing his elite video-editing skills with his distinct voice and opinion. Luckily for him, baseball fans all over the country have tuned in.

At the start of the season, Jomboy had roughly 10,000 followers on Twitter. Now he has over 67,000, gaining more than 5,000 Thursday night after posting his audio masterpiece from Boone’s ejection.

The video has already been viewed 2.2 million times with over 13,000 retweets and over 50,000 likes.

“The attention has been amazing and we have had a lot of people reach out and spread what we’re doing. All the credit goes to everyone that followed, listened and supported from the beginning,” O’Brien said. “We have an amazing community. I know hundreds of names and Twitter handles that have been about of this with me from the beginning.

“I think they feel a sense of pride and that they are a part of the ride with us, which is the most rewarding part for me because they are.”

It’s not the first time that an O’Brien product has gone viral, with Jomboy Media drawing over 200,000 subscribers on YouTube. His website also sells merchandise that is linked to his popular podcast, “Talkin Yanks,” where you can purchase shirts with Boone’s full rant for $25.

T-shirt sales act as the third tier in O’Brien’s revenue stream, with other profit coming from patron support and ads on podcasts and videos. Being first in the market is incredibly important, which is why O’Brien went straight to designing after he edited and posted the viral video Thursday night.

The next step for O’Brien and Jomboy Media is a potential move to an official office during the next MLB offseason. He hopes to have the rest of his team move to the East Coast so that they can work on expanding their podcast network, which already has 14 different shows ranging from New York sports and national sports to history and comedy, movies and pop culture.

“The goal is to keep creating content that fulfills us and entertains our audience,” O’Brien said.
