WASHINGTON - China's history-making freeskier Gu Ailing advanced to the women's Big Air final at the FIS World Championships with a sixth-place finish in Monday's qualification.

Gu, 17, had already won the halfpipe and slopestyle gold medals in Aspen, becoming the first Chinese freeskier with double golds at the same World Championships.

Competing in the Big Air, an event that she has relatively less advantage, Gu scored 69.50 points in the first run before improving it to 88.50 points in the second, finishing sixth to secure one of eight final berths.

Frenchwoman Tess Ledeux led women's qualifications with 95.00 points. She was followed by Italy's Silvia Bertagna at 94.00 points, and Anastasia Tatalina representing Russian Ski Federation at 93.25.

The Big Air final will be staged on Tuesday, the final competition day of this year's Freeski World Championships.
