Nathan Chen of the United States achieved a personal best in the men's short programme at the International Skating Union (ISU) Grand Prix Final in Turin.
The defending and world champion scored 110.38 points at Torino Palavela.
"The second two jumps were a little shaky," Chen said, as reported by Olympic Channel.
"I would definitely like to make those a little lighter, since I know I'm capable of doing that.
"And the program I think I can definitely start feeling the music better."
His closest rival, Olympic champion Yuzuru Hanyu of Japan, had to make do with 97.43 after an error in his routine.
