What was the biggest robbery in Boxing(whether Olympics or Professional)? Personally, I have to say Roy Jones Jr. vs Park Si-Hun in 1988. Jones out landed Si-Hun 86-32. Nobody Alive thought Si-Hun had won the fight, all 3 judges were suspended later and it was turned up that all 3 had been bribed by Korean officials. Other than that, Floyd Mayweather Jr. vs Serafim Todorov in the 1996 Atlanta Olympic Games. Mayweather had beaten Todorov so convincingly that when the decision was announced the Ref accidently raised Mayweather's hand instead of Todorov. The US olympic team filed an official complaint. In The Pros I have to say, Probably Lennox Lewis vs Evander Holyfield I, Lewis beat Holyfield in my opinion 9-3, but 7-5 should have been the closest it could have been judged, but yet somehow the judges managed to score this one a draw.
Jones/Park is probably the worst one I've ever witnessed. He was battering the guy around the ring, it was ridiculous.
Pernell Whitaker v Jose Luis Ramirez I, along with Roy v Park. Martinez v Cintron is up there though, I thought Martinez won 9-3, not to mention knocking Cintron out in round 7, and Cintron's corner entering the ring (DQ).
I can not emphasize enough that Foreman-Briggs made me want to stop watching boxing at all because the game had changed so much. RIDICULOUS!
