MELBOURNE, Jan. 21 (Xinhua) -- Eighth seed Stanislas Wawrinka of Switzerland beat three-time defending champion Novak Djokovic 2-6, 6-4, 6-2, 3-6, 9-7 to reach the semifinals at the Australian Open here on Tuesday.
A year ago, Djokoivc prevailed over Wawrinka in a fourth-round match that ended 12-10 in the fifth set and went five hours and two minutes. Their semifinal match at the US Open in September was another max-distance five-setter but consumed a more modest four hours and nine minutes.
Wawrinka took four hours to eliminate the defending champion who the Swiss lost 14 straight head-to-heads to. Wawrinka also ended Djokovic's 25-match winning streak at the Melbourne Park and made into his career-second Grand Slam top four.
"Last year it was really tough. But this year I came back. I was not feeling great at the beginning. I am really, really, really happy. He is an amazing champion and kept coming back. I was really focused and feeling great on the court. I always fight, I always try. I was cramping. It is never easy," said Wawrinka.
Waerinka ended Djokoivc's bid for a fourth consecutive title at Melbourne Park and will meet Tomas Berdych in semifinals.
"Berdych is a dangerous player with his service and baseline play. I will be ready, though," said Wawrinka.
