1955-05-30 Pascual Perez w co 5 (15) Yoshio Shirai, Korakuen Stadium, Tokyo, Japan - WORLD. Referee: Haruo Ishiwatarido. A battered wreck that was once a world champion, Shirai (111½), who had been given a real working over by Perez (108¼), was counted out at 2.59 of round five immediately prior to the bell. It came as no surprise when Shirai announced his retirement immediately afterwards.
On a number of occasions, Perez risked being stripped when allowing his opponents to make less than eight stone without contractual conditions in place. One such fight was when he outpointed Danny Kid (111¼) over ten rounds at the Luna Park Stadium, Buenos Aires, Argentina on 22 October.
