 As a rising star, Yarosz was featured on the cover of the January 1934 issue of The Ring magazine.He took the NYSAC World Middleweight Title and National Boxing Association World Middleweight Title with a fifteen-round decision over Vince Dundee before a crowd of 28,000 at Forbes Field, on 11 September 1934 in his native Pittsburgh.The bout was close but somewhat dull due to too much wrestling and clinching, though Yarosz seemed to hold the lead in all but the late rounds when he looked visibly exhausted.
