Pierce O’Leary: The “Shark” Taking Over the 140lb Division

If you’re into boxing, it’s time to keep an eye on Pierce O’Leary, also known as “The Shark.” This undefeated fighter, sitting at 16-0 (with 9 KOs), is tearing through the super lightweight division with knockout after knockout. His latest performance at Wembley Arena proved he’s not just climbing the ranks—he’s storming through them. Let’s dive into why O’Leary is a name you’ll be hearing a lot more of in the future.

A Devastating Knockout at Wembley

Last weekend, Pierce O’Leary faced off against Jose Edgardo Perdomo, who stepped in as a last-minute replacement. Despite Perdomo’s lack of elite credentials, O’Leary took care of business like a pro. In the third round, he delivered a perfectly timed left hook that left Perdomo out cold.

“I work my ass off every day, so I don’t expect anything less,” O’Leary told TNT Sports after the fight. He didn’t even need to look to know it was over. “I heard him hit the ground before I saw him,” he added confidently.

O’Leary’s trainer, Joe McNally, deserves a lot of credit here. McNally kept O’Leary sharp despite a chaotic lead-up with opponent changes. Since teaming up in 2023, McNally has been a key part of O’Leary’s rapid improvement. “Pierce puts in the hours, does the hard work, and the results speak for themselves,” McNally said.

O’Leary Is Gunning for the Top of the 140lb Division

What sets O’Leary apart isn’t just his knockout power—it’s his drive and discipline. According to McNally, O’Leary trains with top-tier sparring partners and soaks up every bit of knowledge from them. The goal? To take on and beat the best fighters at 140lbs, including household names like Devin Haney.

“When I started working with him, I could see it immediately. He’s got the talent, the work ethic, and the mindset to go all the way,” McNally said.

O’Leary isn’t here to be just another contender. He’s aiming to dominate the division, and his confidence reflects it. “I’m the shark next year. Watch out,” O’Leary boldly declared.

European Title Shot and Bigger Goals

The next big move for Pierce O’Leary is a shot at the European 140lb title. Originally, Dalton Smith was set to compete for the vacant belt, but after an injury sidelined Smith, O’Leary got the call. This opportunity could catapult O’Leary straight into world-title contention and set the stage for an even bigger 2025.

“That’s the plan, and it’s what Joe and I are working toward,” O’Leary said. He’s not just focused on winning—he’s making a statement to every fighter in the division. “The same thing. The exact same thing,” he said, referencing the fate of his opponents.

If O’Leary secures the European title, it will position him as one of the most dangerous fighters at 140lbs and open doors to global opportunities.
