You can see the complete seventh game all 2hours and 33 minutes of it narrated by Vin Scully. Koufax was pitching his third game in the seven game series with only two days rest and and ailing shoulder. This especially for those Dodger fans now in mourning due to last night's elimination of their team from the playoffs. ed.
It is the 32nd and final world record set in this year of amazing achievements.
China's Ni Chih Chin jumped 7-3¾ on September 29 and followed that with either a 7-4 or 7-4¼ in an unspecified meet. Brumel will be unable to respond to this challenge because on October 7 he fractured his ankle in a motorcycle accident. It will be at least a year until he is able compete. The king is dead (at least temporarily). Long live the king.
Brumel nearly had his lower right leg amputated just above the foot. He never fully recovered, tried a long painful comeback as seen in the above video. The injury was to his lead leg not the take off leg, and it is clear that he has a lot of pain while doing his approach.
A bit more on his life which ended at age 60 a few years ago. Found on Wikipedia.
