Jamie McDonnell dedicated his victory to the people of Doncaster after winning the vacant IBF bantamweight title in front of his home crowd against Julio Ceja.
McDonnell won thanks to a majority points decision against the big-punching Mexican youngster.
The 27-year-old admitted that it was an unbelievable feeling to be world champion and revealed that he enjoyed the fight.
"Oh my god, what an amazing feeling," he told Primetime after the fight. "In the first five rounds or so I felt him out and wanted to come on stronger as the fight went on.
"I started digging him in the last few rounds and I felt I could've got the stoppage. I was actually enjoying it. He had a big record with 22 knockouts but I dug in because I wanted the belt. I controlled that fight.
"There were a few anxious moments when he caught me but I enjoyed that last round more that I've ever enjoyed a round. It means everything to me and this belt is for the people of Doncaster."
Ceja was previously unbeaten and had stopped 22 of his 24 opponents. McDonnell improves his record to 21 wins from 24 fights.
