Russian Yevgenia Medvedeva became the first female figure skater to repeat as world champion since Michelle Kwan in 2001.
U.S. champion Karen Chen, in her worlds debut, finished fourth to clinch the maximum three 2018 Olympic spots for the U.S. women.
The skaters to fill those spots will be announced after the January 2018 U.S. Championships, but Chen is now the front-runner after her surprise U.S. title in January and the struggles of Ashley Wagner (seventh at worlds) and Gracie Gold this season.
Medvedeva smashed her world record for free-skate and total scores, ending up with a flawless seven triple jumps and 233.
