Murray Joins Federer, Nadal in Aussie Open Semis

Andy Murray overcame an inconsistent serve to beat Kei Nishikori on Wednesday and reach the semifinals of the Australian Open for the third straight year.

The No. 4-ranked Murray won 6-3, 6-3, 6-1 to join No. 2 Rafael Nadal and No. 3 Roger Federer in the semifinals. Top-ranked Novak Djokovic had a chance to complete a powerful final four later with a win over David Ferrer of Spain.

Nishikori, the first Japanese man to reach the quarterfinals here in the Open era, showed flashes of the form that earned him a surprise win over former finalist Jo-Wilfried Tsonga in the previous round.

During the first set, Nishikori played a lob shot through his legs on his way to winning the point — but by that time he was already a break down.

Murray, who hasn't dropped a set since the first round, broke seven times in all, although he plans to work on his serve after only managing a 44 percent success rate with his first serve.

"The returning was good, so that was positive," said Murray, who lost in the Australian Open final the last two years. "Could have served better, that's for sure."

Murray will face either Djokovic, who beat him in last year's final, or Ferrer on Friday. Federer and Nadal will meet for the 27th time in the other semifinal, scheduled for Thursday.

Federer beat 2009 U.S. Open champion Juan Martin del Potro 6-4, 6-3, 6-2 Tuesday in his 1,000th tour-level match. Nadal rallied for a 6-7 (5), 7-6 (6), 6-4, 6-3 win over Tomas Berdych.

Their match on Thursday will be their 27th in all and 10th at a major, but their first in a Grand Slam semifinal since 2005.

Yelling "Vamos," disputing line calls, pumping his arms after winning big points and bounding around like a hyperactive kid, Nadal ripped winner after winner against Berdych in a 4-hour, 16-minute display of pure intimidation.

Federer finished his match with one of his classic, one-handed backhands against Del Potro, one of only two men who have beaten him in a major final. The other is Nadal, who has done it six times.

Thursday's match will be the first time Federer and Nadal have met at Melbourne Park since the Spaniard won the 2009 title in five seesawing sets. Nadal collected the trophy from the great Rod Laver after consoling Federer as he sobbed in the background.

"We are talking about a player who has won 16 Grand Slams, and I've won 10," Nadal said. "We have played a lot of matches together, many in very important moments for our careers. So the matches against him are always special, even if we are (ranked) 20 against 25."
