Chamberlain Halts O'Leary in Dublin Battle
Mark Chamberlain handed Pierce O'Leary the first defeat of his professional career on Saturday night, stopping the hometown fighter in the tenth round of a bruising super-lightweight clash at Dublin's 3Arena. Chamberlain weathered a ferocious mid-fight comeback from O'Leary before landing a decisive blow to end the contest.
Early Knockdowns and O'Leary's Seventh-Round Rally
Chamberlain established authority early, breaking through O'Leary's guard in the second round with a sharp left hand that sent the Dubliner down. The Portsmouth fighter pressed the advantage immediately in the third, threading a clean uppercut through the center to drop O'Leary for a second time.
Backed by a vocal home crowd, O'Leary reorganized his defensive structure and mounted a counter-offensive. In the seventh round, O'Leary found the breakthrough, driving a compact shot into the ribs that caused the wet clap of leather against flesh and folded Chamberlain to the canvas against the ropes.


Tenth-Round Finish and Future Rematch Talk
The momentum proved brief. In the tenth round, Chamberlain reset his footing and detonated a heavy right hand that destabilized O'Leary entirely, forcing the referee to step in and wave the contest off without a count.
The victory puts Chamberlain back on track following his draw with Jack Rafferty last August. "I'm not a stranger to an away day, and anyone that knows me deep down knows I will fight anyone, anywhere," Chamberlain said. "If it means I've got to go in the champion's back garden, I'll do that. But I take my hat off to Pierce because he's a true champion and he'll come again."
O'Leary, having surrendered his unbeaten record, immediately targeted a second meeting: "I thought I was well back in the fight when it happened but it is what it is. Mark was the better man on the night. A fight like that, I think we all want to see a rematch."
Under the dark arterial spots beside the bottom rope, the canvas remained a pale, unwashed beige.
