In the other semifinal, fellow Serb Jelena Jankovic, seeded three, takes on fifth-seeded Russian Maria Sharapova on Thursday.

Hantuchova, 25, emphatically announced her Grand Slam comeback when she outclassed Radwanska for the loss of just four games.

The win ended Radwanska's giant-killing run, which included second seed Svetlana Kuznetsova and former world No 3 Nadia Petrova, and confirmed the 25-year-old Slovak's return to the big time.

She is in her first Grand Slam semi-final and it comes five years after her last Grand Slam quarter-final appearance here.

"It feels great. Every tennis player knows what I'm talking about when you get to that point when you feel like everything you touch is going in and I want to go on as long as possible," she said,

Djokovic was in dazzling form against Ferrer, but admitted nerves got the better of him as he tried to close the match in the third set.

"I even surprised myself with the way I played today, especially in the first two sets, but in the end I was very, very nervous," he said.

"You always try to improve and I'm very happy that I am performing my best tennis in the major events, this is just the start, so hopefully I can get all the way."

The Serb has advanced without dropping a set in his five matches, stretching his winning streak on hardcourt to nine matches.

"He's done a phenomenal job, four semifinals of Grand Slams at his age, I was never close to that at his age, he's improved so much in the last couple of years and it's exciting playing the best in the world," Federer said.
