Karl Mildenberger was solidly favored to beat the rugged but crude Oscar Bonavena, and some handicappers set odds of 4 to 1 favoring the German. Bonavena, however, turned out to be much too strong for Mildenberger in the ring. Mildenberger was knocked down four times by the powerful Argentine and lost the 12 round decision by scores of 56-48, 57-53, and 57-53.
