Intro:

American Cameron Naasz knocked Canada's Kyle Croxall off the top of the Ice Cross Downhill World Championship standings on Saturday, after victory in Lausanne, Switzerland.

Script:

The Swiss city of Lausanne was the setting for the fourth round of this season's Ice Cross Downhill World Championship.

Starting at the 15th century Chateau Saint-Maire, the 450-metre track was a true test of courage for the 64 athletes.

Kyle Croxall arrived at the top of the standings - but the Canadian got just 110 points with a dreadful 20th place after losing in the round of 32, and is now second.

It was a better day for Kyle's brother Scott who secured a place in the four-man final.

He was up against Miikka Jouhkinmainen of Finland, Austrian Kim Mueller and the USA's Cameron Naasz.

Naasz, a 23-year-old college student from Minnesota, triumphed
