Marco Huck retained his WBO cruiserweight title by beating Ola Afolabi in Berlin on Saturday night.
The German won on a majority decision in the third meeting against the challenger from England.
South African judge Deon Dwarte scored the bout 115-113 in favour of Huck. John Madfis of the United States had it 117-111 but there was some surprise at the Max-Schmeling-Halle when Lahcen Oumghar of the Netherlands scored it 114-114.
The champion did not look overly troubled and improved his record to 36-2-1, including 25 knockouts. Afolabi dropped to 19-3-4, with 9 knockouts.
Huck also retained his belt on a majority draw in May last year and beat the Briton on a narrow unanimous decision in May 2009.
"Today, I proved that I am first and foremost a boxer and not just a warrior inside the ring," said Huck after the fight, his eleventh defense of the WBO Title. "This time, I was in tip-top shape - unlike to last year's clash with Afolabi, where I was nowhere to my current level of fitness. I was focused on the task ahead of me and it showed."
He has made 11 successful defences of the title he won from Victor Emilio Ramirez in 2009.
