Hurkacz faces 'unbelievable' Federer for Wimbledon semi-final spot
Poland's Hubert Hurkacz celebrates winning against Russia's Daniil Medvedev during their men's singles fourth round match.
The Pole has only met Federer once -- a straight sets loss at Indian Wells in the quarter-finals in 2019.
That dismal streak included defeat in the first round of the French Open to world number 154 Botic Van de Zandschulp and first-up losses in the grass court events at Stuttgart and Halle.
The defeat in Stuttgart was particularly painful as it came at the hands of Dominic Stricker, ranked a lowly 335 at the time.
Hurkacz's last-16 tie had started on Court Two on Monday but was suspended with him 4-3 up in the fourth set.
It was completed under the Centre Court roof in front of a capacity crowd of 15,000.
"Daniil is an unbelievable player, we were battling on Court Two, then we came back to finish the match.
"He is number two in the world, has unbelievable skills. Stopping yesterday at the end of the fourth set was a first time for me, I had talks with my coach and worked with my physio to prepare for today and do the things better than yesterday."
The loss left Medvedev still searching for a first appearance in the Wimbledon quarter-finals.
Hurkacz, 24, follows in the footsteps of fellow Poles who made the last-eight at the All England Club -- Wojtek Fibak (1980) and Jerzy Janowicz and Lukasz Kubot (2013).
