In doing so, Berdych avoided becoming the first man to lose 18 straight tour-level matches against a single player. It marked his first win over Nadal since the 2006 Madrid quarterfinals.

The 29-year-old Czech has not dropped a set this fortnight, and awaits the winner between three-time finalist Andy Murray and 19-year-old Australian Nick Kyrgios, who face off on Tuesday night.

Berdych also reached the semi-finals last year in Melbourne.Nadal, the 2009 champion, was facing a top 10 opponent for the first time since defeating Novak Djokovic in the 2014 Roland Garros final.
