BOSTON -- Spain's Javier Fernandez defended his world title Friday, turning a daunting deficit into a lopsided victory when he skated flawlessly. Training partner Yuzuru Hanyu struggled throughout his long program.
Fernandez cleanly landed three quadruple jumps and had the crowd on its feet before he finished his final spin to Frank Sinatra singing "Guys and Dolls." He smashed his previous personal bests with 216.41 points for 314.93 total.
Hanyu settled for his second straight silver. Jin Boyang landed four quads to win bronze, the first individual world medal for a Chinese man.
Hanyu, who led by more than 12 points coming in, fell once and touched his hand down two other times in a performance that was tentative from the start.
He overcame two falls in his free skate in Sochi to win Olympic gold, but had no such luck at Boston's TD Garden. Fernandez, who, like Hanyu, is coached by two-time Olympic silver medalist Brian Orser, had no such trouble Friday.
Channeling Sinatra, Fernandez was at his charming best as the crowd clapped along to his fancy footwork. Fernandez buried his face in his hands when it was over.
He said "if I have a chance to win, I have to have a clean program" when he stepped on the ice after Hanyu.
"And I did it," Fernandez said, his voice trailing off.
Hanyu, the 2014 world champion, still earned 184.61 points for a total 295.17, strong scores for just about any other skater but well off his records.
A hand touched down on his opening quad salchow, and the mistakes kept coming. Hanyu fell on his second quad salchow, costing him the points of a combination. He stepped out of his landing on his second triple axel, resulting in just a double salchow instead of a triple in the combination. Then a hand touched down again on his final jump, a triple lutz.
He stayed hunched over for several moments after it was over, as dozens of flowers and stuffed animals flew onto the ice in a show of his stardom with many Japanese fans in the crowd.
Jin became the first man to land four quads at worlds, but his scores were so low for choreography and interpretation that he still couldn't match the world's best. He scored 181.13 points for 270.99 total.
Patrick Chan, the three-time world champ who took last season off, dropped from third to fifth after a mistake-filled long program.
American Adam Rippon was sixth after a stirring skate to his Beatles medley that had the home crowd roaring.
Earlier, China's Sui Wenjing and Han Cong took the lead after the pairs short program to capture their first world title.
Wenjing and Cong, last year's silver medalists, scored 80.85 points to top defending champs Meagan Duhamel and Eric Radford of Canada, who earned 78.18. Olympic gold medalists Tatiana Volosozhar and Maxim Trankov of Russia were third with 77.13 points after taking last season off.
