World number two Roger Federer will make a 14th appearance at an Australian Open semi-final after beating Tomas Berdych of Czech Republic in straight sets.
The defending champion saw off the 19th seed 7-6 (7-1) 6-3 6-4 in the Rod Laver Arena night session to seal an eighth win out of their 10 Grand Slam meetings.
The 36-year old will now face unseeded 21-year-old Hyeon Chung of South Korea on Friday for a place in the final.
Speaking after his victory, Federer said: “I hung around, got a bit lucky, a bit angry, a frustrated, maybe at the umpire, but I actually thought the call was good anyway!”
“I was just frustrated and a bit antsy. I’m happy I got out of that first set. It ended up being key to the match. Tomas was great.” the second seeded player added.
