Pierce O’Leary won the battle of the bangers and stopped previously unbeaten Hovhannes Martirosyan (Belgium) last March 16th in Birmingham (UK).   The Dubliner dropped the Belgian in the first round with a perfect left hook and opened up a cut in the rounds that followed.   The challenger eventually succumbed to a beautifully executed and power-packed left hook which dropped him again at 36″ to the end of round nine.   The stoppage is the eight in Pierce’s career up to date (14-0, 8).   Queensberry of Frank Warren promoted. Pierce retained his WBC International Superlight weight title with this outstanding win.
