Tomas Berdych is the first man through to the Australian Open semi-finals after a four-set victory over David Ferrer.
Berdych had lost seven of his past 11 meetings against the No 3 seed, however the Czech never looked back after a dominant start.
The seventh seed controlled the play to win the first two sets in emphatic fashion and although Ferrer threatened a comeback by winning the third, Berdych was able to seal a 6-1 6-4 2-6 6-4 victory in three hours four minutes.
Berdych broke Ferrer five times, firing down 10 aces and 43 winners in the process. The 28-year-old was guilty of making too many unforced errors - 62 in total - however Ferrer was unable to take his chances.
Berdych's reward for a first-ever win on Rod Laver Arena is a last-four clash with Stanislas Wawrinka, who stunned defending champion Novak Djokovic in an epic five-setter later on Tuesday.
"It feels great. It's really a great feeling," Berdych said.
"There were some special moments which went well together in this match: making it for the first time here in the Aussie Open to the semis, winning my first match on Rod Laver after all those years. I'm extremely happy to go through.
Berdych began confidently and mowed through the first set in half an hour before capturing the decisive break at 4-4 in the second with a fierce backhand down the line before serving out the set with an ace.
He did have his powerful serve broken for the first time after 60 consecutive holds in the tournament as the Spanish baseline slugger, bidding for his third Australian Open semi-final, hit back by winning the third set as the rangy Czech imploded in a hail of unforced errors.
Ferrer looked to be getting on top of a tiring Berdych as the match entered a fourth set.
But the 28-year-old broke Ferrer's serve in the fifth game and served out for the match with a huge serve.
In getting the win, Berdych became the first Czech to reach the last four in Melbourne since Jiri Novak in 2002.
