MELBOURNE, Australia — Only the trophy and the tears were missing from this latest Grand Slam installment of Rafa vs. Roger. Rafael Nadal and Roger Federer were on opposite sides of the net Thursday, meeting in the semifinals of the Australian Open. And Nadal was the winner again, for the eighth time in their 10 Grand Slam matchups. He won 6-7 (5-7), 6-2, 7-6 (7-5), 6-4, covering the baseline with incredible speed and hitting forehand winners from almost impossible angles. He applauded as Federer started to leave the stadium, then ran back onto the court, dropped onto his haunches and pumped his arms in triumph. All that, three days before the final, where he faces the winner of today's semi between defending champion and No. 1-ranked Novak Djokovic and Andy Murray.The latest Grand Slam meeting between Nadal and Federer — who have won 26 majors between them — was a semifinal worthy of a final. Nadal didn't excuse his celebration but explained it as letting off steam. Nadal has labored with injuries since losing the U.S. Open final last year. On the eve of this tournament, he hurt a knee while he sat in a chair at his hotel and thought for a while he wouldn't be able to play. He has played with his right knee heavily strapped."Twenty-four hours to play my first match, I was in my room crying because I believe I didn't" have the chance to play, Nadal said. "So it was a very, very tough situation for me, these hours. "Two weeks later, I am here in the finals. … It's one of the victories that's going to stay in my mind forever."Federer said it feels like Nadal plays his best tennis against him. "We have had good matches over the years. I enjoy playing him. The crowd really gets into it, which is nice," Federer said. "We have a lot of respect for each other, which is good, too, I think."

"It's nice to get that far again after losing quite early in the last couple of years."Sharapova, seeded fourth, overcame Petra Kvitova 6-2, 3-6, 6-4 in the semifinals, and third-seeded Azarenka beat defending champion Kim Clijsters 6-4, 1-6, 6-3.Azarenka worked on her fitness in the offseason, giving her the confidence to know she can play "as long as I need.""Even if you believe 1 million percent (you're going to win), it's not going to happen," Azarenka said.
