September 9(SEE): Australian John Millman pulled off one of the greatest tennis upsets in history, defeating Roger Federer to reach the US Open quarter-finals.
Millman, who had never previously beaten a top ranked opponent, appeared to have even less chance of winning with Federer a set and a break up and holding two set points, but he somehow clawed his way back to attain a 3-6 7-5 7-6 (8/6) 7-6 (7/3) victory.
