Rampant Rafael Nadal battered ex-world number four Tomas Berdych Sunday but said he would be taking a step into the unknown against "dangerous" Frances Tiafoe in the Australian Open quarter-finals.
Berdych is set to play Fabio Fognini of Italy, who defeated Frenchman Julien Benneteau 3-6, 6-2, 6-1, 4-6, 6-3 in three hours.
"I'm happy the way the day went" said Roland Garros and US Open champion Rafael Nadal.
The 31-year-old Berdych, the World No.15, fell apart in the third set, failing to hold serve.
