Mitchell was a very good boxer and a sharp puncher not well known due to the political situation in south Africa at the time .I think he would outbox Jeff and.win on points .Mitchell was the naturally bigger man fighting at the higher weight all his career.One of the few who could handle fenick .
Competitive matchup. I'll go with Fenech by decision something like 7-5 or 8-4. 100 percent sure there is no KO either way.
