Alysa Liu of Richmond became the youngest woman in history to land a difficult triple axel jump in an international competition.

Liu, 12, landed the 3 ½-rotation jump Thursday on the way to winning her division at the Asian Open Trophy in Bangkok, Thailand. She joined Tonya Harding, Kimmie Meissner and Mirai Nagasu as the only American women to land a triple axel in a competition. Nagasu did it earlier this year at the Pyeongchang Games.

“It was very emotional for me to watch her making history, to land a clean triple axel in an international competition at age 12,” father Arthur Liu said in an email.

The girl who trains at the Oakland Ice Center competed in the advanced novice women’s division in Thailand because of her age. Liu won the U.S. junior title in January but was too young to compete at the 2018 Junior World Championships.

“Now she is working on the consistency,” the father said. “She needs to build up her strength and get this jump consistent.”
