The second quarter was particularly bleak for Belgium as they scored just seven in the quarter.
Hungary capitalized and a 15-4 run over the final 7:40 of the first half put the visitors up 35-24.
Marton Bader scored eight points during the streak and ignited the run with a dunk.
Bader finished the game with 16 points and 10 rebounds.
Belgium failed to score the final two minutes of the first quarter and the opening two minutes of the third and thus were held to a meager seven points over a 14-minute stretch.
Axel Hervelle got Belgium’s offense going and his three put them down four, 40-36, with just over four minutes in the third.
Kaman had an answer though, as he drilled a three-pointer to ignite an 11-3 Hungarian run to close the third quarter.
Hungary led 51-39 to start the fourth and Belgium would get no closer than eight points in the final stanza.
