Russia's Roman Karmazin beat champion Kassim Ouma on points to claim the IBF light middleweight title on Thursday. Karmazin, 32, knocked the Ugandan down twice in the third round before winning a unanimous 12-round decision.
The 26-year-old Russian had lost his only previous world championship bout, to Spain's Javier Castillejo in 2002.
But this was never a close contest and Karmazin swept the judges cards 118-108, 116-110 and 117-109.
Ouma said: "I told everyone that he was a good fighter, but not a superstar.
Karmazin said: "He was a tough fighter, lots of stamina, but not as good as I was.
"If he wants a rematch, we will definitely talk."
