I think this fight would be almost 50-50, Wardley hits harder and finishes his opponents earlier while Hrgovic goes for more rounds, in any case this would be a great fight.
Hrgovic by easy KO. The difference in skills and talent in immense. Yes, Hrgovic struggled badly against Zhang, but Wardly wouldn't likely last two rounds against Chinese giant.
I'd favour Hrgovic but Wardley has real power and is dangerous when hurt. Hrgovic was being stunned by glancing shots against Zhang, so I'd give Wardley a punchers chance.
