1981-10-03 Sergio Victor Palma w pts 15 Vichit Muangroi-et, Luna Park Stadium, Buenos Aires, Argentina - WBA. Referee: Carlos Berrocal. Scorecards: 147-141, 148-138, 148-141. In a contest with no quarter given, it was the champion’s greater accuracy that ultimately gave him the advantage over the aggressive Muangroi-et (122). The opening rounds were even before Palma (122) moved ahead using a hard left jab to pave the way to victory. The Thai never gave up trying and in the 14th and 15th sessions went after Palma, who fought back with flurries of rights and lefts to the head that stunned his rival but failed to halt him.
