In one of his most difficult matches, Ambers defeated Fritzie Zivic on July 1, 1935, in a ten round unanimous decision in Millvale, Pennsylvania. Ambers took the lead in the opening rounds, and had enough of a points margin to take the decision, but in the last two rounds he retreated often, his jaw being broken in the ninth by what appeared to be a right to the chin. Zivic opened up with a right handed attack in the ninth and tenth that was simply not adequate to overcome the large points margin opened by his opponent. Ambers was examined by a local hospital after the bout and released.
