NAGANO – Japan's Olympic figure skating champion Yuzuru Hanyu broke his own world best in the short programme at the NHK Trophy on Friday, posting an eye-popping score of 106.33 points. After Chinese teenager Jin Boyang earned 95.64 for a dazzling skate in Nagano, Hanyu responded in style as he nailed every element, including an exquisite quadruple toe-loop, triple toe-loop combination. "You try not to think about your rivals but I saw (Jin's) skate on TV and told myself to get out there and beat his score," Hanyu said after eclipsing his own previous high of 101.45 set at the 2014 Sochi Olympics. "I'm surprised and I'm happy, but mostly relieved. It shows I've been working on the right things in practice. People might think 'Hanyu is back' but I know I've still got room to improve."
