Murray Wins over Dolgopolov to Reach Aus Open Semis

Britain's Andy Murray outgunned exciting newcomer Alexandr Dolgopolov to reach the Australian Open semi-finals, as Kim Clijsters and Vera Zvonerava set up a heavyweight last-four clash Wednesday.

Murray dropped his first set of the year against Ukrainian shot-maker Dolgopolov, 22, who dominated a third-set tie-break before going down 7-5, 6-3, 6-7 (3/7), 6-3, ending a breakthrough Grand Slam run.

The fifth seed, last year's runner-up to Roger Federer, admitted it was hard going against the unpredictable Dolgopolov. Murray will play either world number one Rafael Nadal or David Ferrer in Friday's semi-final.

"It was very tough and every point was different, he hits the ball different to a lot of other players and I struggled a little bit with my rhythm early on," Murray said.

"He came back at me well in the third set but I thought I did well enough."

Murray, 23, is now into his fifth Grand Slam semi-final as he bids to break a British men's major drought stretching back to Fred Perry's 1936 US Open win.

Dolgopolov, who was making his debut in Melbourne and playing only his fourth major, had shocked world number four Robin Soderling in the previous round.

Earlier three-time Grand Slam-winner Clijsters beat Poland's Agnieszka Radwanska 6-3, 7-6 (7/4) to reach her sixth Australian Open semi, while world number two Zvonareva downed Petra Kvitova 6-2, 6-4.

The players were badly distracted by celebrations marking Australia Day, a national public holiday, including a thunderous 21-gun salute nearby as Zvonareva was broken in the second set.

Clijsters was later put off by a formation fly-past by military jets which screamed low over Melbourne's Rod Laver Arena as she played Radwanska.

"No one told me there would be the noise (from the cannons). I was trying to keep my concentration but I was a bit distracted," Zvonareva said.

A medical drama involving a female fan also disturbed the Russian, but she recovered from losing her serve in the second set to quickly close it out against the tiring Kvitova.

Zvonareva wore a black ribbon on her cap to support victims of Monday's deadly suicide bombing at Domodedovo airport in Moscow, her home city, which killed 35 and left her frantically calling relatives.

"You're calling back home and making sure everyone is okay, the people that you know," she said. "I just tried to put it away. It happened, it is terrible. But you try to move on."

The 26-year-old remains on course for her third straight Grand Slam final, after losing to Serena Williams at Wimbledon and Clijsters at the US Open in September.

Clijsters overcame a high mistake rate to see off Radwanska, who played a limited game but stayed in the match with some scrambling defense, taking advantage of the Belgian's 37 unforced errors.

"Everything has to be better (against Zvonareva)," Clijsters said. "I mean, serving, returning, the unforced errors. Everything has to be better."

World number one Caroline Wozniacki will face China's Li Na in Thursday's other semi-final, with both women seeking their first Grand Slam wins.
