Daniela Hantuchova has accused Ana Ivanovic of gamesmanship after the Serb won their Australian Open semi-final.
Hantuchova claimed Ivanovic squeaked her trainers intentionally
Hantuchova, who let slip a 6-0 2-0 lead to lose 0-6 6-3 6-4, claimed she was regularly put off in serving by a squeak when Ivanovic shuffled her feet.
"I was really surprised with that," said Hantuchova, claiming umpire Alison Lang ignored her early complaint.
"I think it's unfair. It's a distraction to the server. We played before and she never did it."
Maybe she was just trying to pick on something, to get upset
However, Ivanovic said she did not deliberately make a squeaking noise, blaming the new court surface in Melbourne.
"I just tried to move my feet, to return the ball, so it really was not intentional," she explained.
"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 but there was nothing I could do. 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 disputed the ball on the point that gave the fourth seed the vital break in the final set.
But the Slovakian, appearing in her first Grand Slam semi-final, 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.
"I thought it was a double bounce [on the return at the end of the fourth set] but maybe it was just my mistake. I should have played the point anyway."
