BEIJING - China's Olympic champion Su Yiming survived a late scare in his final run to clinch gold in the men's event at the FIS Snowboard Big Air World Cup here on Saturday, securing back-to-back victories this season.

After having won the season opener in Chongli the previous weekend, Su appeared set for another victory after posting a leading score of 177.5 points from his first two runs.

However, Japan's Kira Kimura, who sat second after the first two rounds, landed a switchback 1980 drunk driver on his final attempt, scoring 91.25 points to overtake Su with a total of 178.25.

Spurred on by an enthusiastic home crowd, Su responded by repeating the switchback 1980 melon from his second run but executed it more cleanly, raising his total to 181.00 points to claim the title.

"Winning back-to-back titles today was really not easy. Last year I had my worst final result here, and I told myself I had to work hard to come back stronger," said the 21-year-old. "I'm really happy to have achieved that today."

"It's a great start to the season, but it's not something I feel overly happy or proud about. Our ultimate goal is the (2026) Milan-Cortina Winter Olympics and I need to stay calm and focused, taking each day of training seriously," he added.

In the women's competition, Britain's Mia Brookes built a commanding lead over her first two runs to claim gold, with Hanna Karrer of Austria and Japan's Momo Suzuki taking silver and bronze, respectively.
