Switzerland's Stanislas Wawrinka knocked defending champion Novak Djokovic of Serbia out of the Australian Open with a 2-6, 6-4, 6-2, 3-6, 9-7 win.
"I'm really, really, really, really, really happy," the 28-year-old Wawrinka said.
Wawrinka advanced to the Australian Open semifinals for the first time and ended Djokovic's quest for a fourth straight title in Melbourne.
"He took his opportunities. He deserved this win today. I congratulate him absolutely. There is nothing I can say. You know, I gave it my best. I gave it all," the 26-year-old Djokovic said.
Djokovic had a 25-match winning streak going at the Australian Open, where he has won four titles.
"The beginning was not that easy, but then I start to play really well. It was important to stay with me. Yeah, after losing two times against him in Grand Slam in five sets, I'm really happy to take that one. It's great for me," Wawrinka said.
Wawrinka's opponent in the semis will be the Czech Republic's Tomas Berdych, who beat Spain's David Ferrer 6-1, 6-4, 2-6, 6-4.
On the women's side, China's Li Na beat Italy's Flavia Pennetta 6-2, 6-2, while Canada's Eugenie Bouchard defeated Serbia's Ana Ivanovic 5-7, 7-5, 6-2. EFE
