A disappointed Hantuchova let slip a 6-0, 2-0 lead and later criticized the fourth seed, saying the way she shuffled her feet before the server hits the ball, which results in loud squeaking, was off-putting and unfair.

"That was ridiculous, I think," Hantuchova told reporters.

"I was really surprised with that. I think it's unfair. It's a distraction to the server. We played before and she never did it."

Hantuchova said she had complained to umpire Alison Lang.

"In the first or second service game (she told the umpire), but she didn't do anything about it. I don't think that (the squeaking) was very nice."

But Ivanovic said she did not deliberately make a squeaking noise.

"I just tried to move my feet, to return the ball, so it really was not intentional," Ivanovic said.

"If you see other matches I was doing exactly the same thing. It's just the way these courts play. And if you listen to the guys I think they're doing the same thing.

"Once I saw she was complaining (to the umpire). But there was nothing I could do, because if I want to move my feet to return a ball, you know, this was the sound I was producing.

"And also, during the point, if I want to run with small steps around the ball, it was exactly the same thing. So maybe she was just trying to pick on something, to get upset."

Hantuchova gave Ivanovic little more than a cursory handshake at the end, having thought the Serbian had not got to the ball on the first bounce on the point that gave the fourth seed the vital break in the final set.

But the Slovakian, appearing in her first grand slam semifinal, said she was just disappointed with her defeat.

"It's just tough, tough to accept that you lose. So I just wanted to get off the court as soon as possible.
