Yarosz defended the Pennsylvania version of the middleweight title against Jimmy Smith on February 12, 1934, winning in a fifteen-round unanimous decision before a crowd of 5,000 in Pittsburgh. Yarosz took the offense through most of the long bout, and there were no knockdowns by either competitor. Yarosz dominated the fighting in the eleventh and twelfth. Smith forced the fighting in the thirteenth through fifteenth rounds, but was ineffective against the left of Yarosz. The United Press gave Yarosz all but the first, second, ninth, and thirteenth. The blows of Smith were well defended by Yarosz with his gloves and elbows, while Yarosz continuously shot through his left and connected nearly every time.
