1960-04-16 Pone Kingpetch w pts 15 Pascual Perez, Lumpinee Stadium, Bangkok, Thailand - WORLD. Referee: Lorenzo Torrealba. Scorecards: 145-143, 137-148, 140-147. A gruelling contest saw Kingpetch (110¾) make good use of his reach advantage to tot up points from long range, while Perez (112) looked to get inside. From the tenth round onwards both men were bleeding from eye wounds, and at the final bell it was very tight. On winning, Kingpetch became Thailand’s first ever world champion.
Once the Kingpetch v Perez return was done and dusted it seemed as though the fourth-rated Hiram Bacallao would be challenging the winner, having won the Cuban title and then beaten Mario De Leon, Ramon Calatayud and Oscar Suarez in quick succession. Unfortunately, he never quite shook off the effects of a serious road accident and following a no-contest against Larry Pineda, and wins over Ward Yee and Jose Luis Martinez, he had just seven more contests, winning one of them, before retiring.
