AUSTRALIAN athletes have had a record day at the winter X–Games in Aspen, USA, featuring a first ever double medal performance in the halfpipe with Mt Buller regular Scotty James claiming his sixth X–Games victory together with Valentino Guseli in bronze.

In snowy conditions in front of a huge crowd at the Aspen halfpipe, James was again the dominant rider, with two outstanding runs giving him back–to–back victories at the event.

With victory secure, James could perform a "victory lap" on his third and final run, high fiving the crowd on his way down.

Jakara Anthony, anther Mt Buller regular, has remained the number one ranked mogul skier in the world, following a silver medal performance in Val St Come, Canada, her fifth medal of the season.

After advancing through to finals in first place, Anthony scored 81.88 points in the super final to be just edged out of first place by 0.37 points to Anri Kawamura of Japan.

After four events, Anthony is ranked first on the mogul standings with 380 points, with French skier Parrine Laffont in second with 270 and Kawamura in third on 248.

"Definitely a solid performance, obviously wanted that top sport, but so does every girl out there, so you have to be laying it down every run," said Anthony.

The mogul athletes will compete again tomorrow at Val St Come in a dual event on the same course.
