The runs would prove crucial when Australia won by 45 runs.
"One of the Indians would have done that," said McCosker later. "One of the Englishmen would have done that. Randall in his innings, he got sconed by Lillee. He just got up and continued to bat. So you just do it... If you get kicked off a horse, you get back on again. Also because it was such a big match and such a big crowd, I wanted to be a part of it. And do something. Not just sit in the dressing room. Anyway, the guys would have been pretty sick of the sight of me in the change room. It was pretty ugly."
McCosker toured England in 1977. His jaw had to be rewired.
During the tour it came out that he had signed to play World Series Cricket.

McCosker later said he enjoyed World Series Cricket. "I played a standard of cricket that I don't think I would have played otherwise", he said. "It was such a strenuous program of cricket at such a high standard over a long period of time. It was professional ... I like the ideals of amateurism, but that doesn't pay the bills and provide you with a future.. Probably the worst thing was being barred from playing Sheffield Shield cricket".

"Leadership is a demanding task and the amount of time spent away from home and business at this time of my life can present long term problems."
