Notably, he beat Juan Laporte and Bashew Sibaca in Sibaca's home country of South Africa... He also dropped Pedroza and was a road warrior, willing to go to the opponent's backyard to fight.
That was a shocker and if Oscar Muniz had not beaten Jeff Chandler earlier in the year, would have won upset of the year, for sure. I dondt consider Dokes-Coetzee such an upset TBH, to me, in 1983, the biggest upsets were Chandler-Muniz 1 and Laporte-Hayes.
