Anthony Crolla knocked out Darleys Perez to become WBA world lightweight champion in Manchester.
Crolla was denied a world belt in July when his first clash with Perez was declared a draw - the decision robbing the Manchester fighter an emotional win in the wake of him sustaining serious injuries while trying to detain a burglar earlier in the year.
However, it was a different story at the Manchester Arena on Saturday night, as a bodyshot proved the Colombian's undoing with 30 seconds of the fifth round remaining.
There was little to separate the two fighters until Crolla's magical moment - with the punishing left taking the wind out of Perez's sails.
The Colombian fell to the floor and failed to beat the count, sparking wild scenes among the home support.
Crolla, 29, told Sky Sports 1 afterwards: "It's been an absolute roller-coaster the last 12 months and this is the perfect finish. It's a dream come true.
"I thought it would be a head shot (that won the fight) but I'll take that bodyshot any day of the week.
"I remember sinking the left in downstairs and, like most people who land a good bodyshot, I knew it was over there and then."
