Belfast's Damaen Kelly dug deep to outpoint Jason Booth and claim the IBO super flyweight title in Huddersfield.
Kelly's all-action style proved decisive in a tough encounter
Kelly showed he has recovered from the demolition he suffered against IBF flyweight Irene Pacheco 16 months ago.
The 31-year-old battled and scrapped his way for 12 rounds to inflict only the fourth defeat on Booth in 29 bouts.
Kelly imposed himself early on and, despite a cut above the eye caused by an accidental clash of heads, managed to stay ahead of a stubborn Booth.
Kelly believed he deserved the win following the close encounter.
"Jason is a tough fighter and is very strong so I tried to stay out of his
way and box on the move," he said.
"I think that, to be honest, I did enough to win it. It was close enough but overall I am pretty sure I shaded it."
