Shock.

Nathan Chen of the United States opened his short program at the World Figure Skating Championships Thursday by falling on a jump in an individual competition for the first time after having stayed upright on 120 straight dating to 2018. That meant he lost a program after winning 19 straight live individual competitions since the 2018 French Grand Prix short. Now in third place, 8.13 points behind the leader, Chen will be hard pressed to win a third straight world title.

Vincent Zhou of the United States, the reigning world bronze medalist, made an utter hash of all three short program jumping passes and finished 25th, one place below what was needed to advance to Saturday’s free skate. That complicates U.S. hopes for three men’s spots at the 2022 Beijing Winter Olympics.

And awe.

Yuzuru Hanyu of Japan may not have been fully content with his skating, but the two-time Olympic champion finished first after making no mistakes in an electric performance that fulfilled the title of his music, “Let Me Entertain You,” by Robbie Williams.

Yuma Kagiyama of Japan, a 17-year-old in his senior worlds debut, skated fearlessly at Mach 2, collected the highest combined scores of the day for two jumping passes with quads and a huge personal best score (100.96) while finishing second to his countryman, Hanyu (106.98).
