ST. MORITZ, Switzerland - Lindsey Vonn skied to victory in a women's World Cup Super-G on Saturday and found herself in an unwitting and unwanted spat with her main rival Tina Maze.

Vonn extended her perfect record in four speed races this season, timing 1 minute, 2.71 seconds to beat World Cup overall leader Maze by 0.37 seconds. Julia Mancuso of the United States was third, 1.01 behind Vonn.

Yet talk soon centred on what Maze's coaches alleged Vonn said as she celebrated after crossing the line.

The 28-year-old American acknowledged that she used a curse word in a release of emotion at taking the lead -- but had not directed it at Maze.

"They think I said something very bad about her when I came to the finish and that is absolutely not true," Vonn said. "I swore and I shouldn't have done that."

Vonn spoke after seeking out Maze, and said she had told her: "I hope you trust me enough to believe me."
