Melbourne: In a stunning performance, World No. 46 Andreas Seppi recorded one of his greatest victories to cause the biggest upset of the 2015 Australian Open yet, knocking out second seed and four-time champion Roger Federer 6-4, 7-6 (5), 4-6, 7-6 (5) for a place in the fourth round Friday.

It ended a 10-match losing streak against Federer, who saw his run of 11 straight semifinal appearances at Melbourne Park come to an end.
