In January 1976, the virtually unknown Mark Edmondson pulled off one of the greatest shocks in tennis history by winning the Australian Open on home soil. Ranked number 212 in the world, Edmondson had been working as a part-time hospital cleaner just weeks earlier. In the final, he defeated the all-time Aussie great, John Newcombe, and he remains the last Australian to win the Open title. Mark Edmondson speaks to Ashley Byrne.
