Roger Federer regained his dominance over Andy Murray in Grand Slam matches and advanced to his 11th consecutive Australian Open semifinal with a 6-3, 6-4, 6-7 (6), 6-3 win on Wednesday.
Federer clinched it on his third match point with an ace to set up a showdown with top-ranked Rafael Nadal, who beat Grigor Dimitrov 3-6, 7-6 (3), 7-6 (7), 6-2.
Murray, who saved two match points in the third-set tiebreaker, has an 11-10 edge over Federer in head-to-head matches, but Federer has won four of five matches in majors.
Murray got angry after a ruling while losing his serve in the ninth game of the third set when he indicated the ball had bounced twice before Federer made a return.
Earlier, two-time defending champion Victoria Azarenka was beaten 6-1, 5-7, 6-0 by Agnieszka Radwanska.
