"Jimmy McLarnin wiped out any question there might be of his supremacy over battle-scarred Billy Petrolle tonight by pounding out a one-sided unanimous decision over the Dakota veteran in an exciting 10 round engagement. McLarnin battered Billy's face, outboxed him, out-generaled him and did everything else one warrior could do to another without exactly knocking him down and out. McLarnin desperately tried to batter Petrolle to the floor but Billy took all the searing punishment that came his way, wobbled occasionally, but always came back for more." -Associated Press
