Satoko Miyahara of Japan dominated the women's free skate to win the Four Continents championship in Chinese Taipei on Saturday.
Miyahara, who was first after the short program, hit all her jumps to finish Saturday with a personal-best score of 214.91 and claim her first international title. Mirai Nagasu of the United States was second with 193.86 points followed by Rika Hongo of Japan with 181.78.
"I was nervous at the start but just tried to believe in myself and all the hard work I've done in practice," Miyahara said. "With elements I feel comfortable with, I was able to skate aggressively."
Katelyn Osmond was the top Canadian finisher, earning 175.63 points for sixth. Alaine Chartrand (11th) and Veronik Mallet (14th) rounded out the Canadian skaters.
Wenjing Sui and Cong Han of China won the pairs championships with 221.91 points ahead of Alexa Scimeca and Chris Knierim of the United States, who took the silver with 207.96 points. Xiaoyu Yu and Yang Jin of China were third with 187.33.
Canada's top pair of Megan Duhamel and Eric Radford were second after the short program, but had to withdraw due to an illness.
"Meagan tried to do the practice this morning but it wasn't going to happen," Radford said. "I think at this point it's just not worth it to push ourselves and risk any sort of injury before the world championships.
"It's time to recuperate and build towards Boston."
Their teammates Lubov Iliushhechkna and Dylan Moscovitch placed fifth (179.67), while Vanessa Grenier and Maxime Deschamps were eighth (148.82).
"There were some big improvements particularly in the triple twist throw and we are pleased to get a level three internationally with that," said Iliushechkina. "Still there were mistakes we shouldn't make."
