Japan's Takahiko Kozuka staged the biggest upset of the Skate America event as he upended Americans Johnny Weir and Evan Lysacek to capture the men's title Saturday night in Everett, Wash.

Sitting in third place, Kozuka performed a relatively clean free skate to earn an overall score of 226.8 points and leapfrog both Weir and Lysacek.

Weir finished second with 225.2, and Lysacek settled for third at 223.21.

Kevin Reynolds, of Coquiltam, B.C., (204.89), Shawn Sawyer, from Edmundston, N.B., (199.98), and Montreal's Ian Martinez (155.18) finished fourth, fifth and 10th, respectively.

Kozuka, 19, was the beneficiary of some major mistakes by both American skaters.

Trailing leader Lysacek by 1.2 points, the Japanese skater fell during his opening quadruple toe loop and put a hand down on a triple Axel. However, Kozuka was given extra credit by the judges for landing four triple jumps late in his program.

"I'm glad I didn't give up and was able to skate to the end," Kozuka said through a translator. "Even more important than the title, it (means) a lot that I showed a good performance. I'm extremely happy."

Weir problems began when he stepped out of a required quadruple toe loop on his opening jump and then dropped the third jump in a combination.

"It was just me being stupid and being cautious on what I was supposed to do in the second half of the program," he admitted. "I was really happy I was able to perform today and focus."

Skating last, Lysacek crashed on his quad toe loop and under-rotated a triple Axel on a three-jump combination.

Unlike Kozuka, Lysacek couldn't come back from his early struggles.

On the women's side, South Korea's Kim Yu-Na leads a strong field after the ladies' short program.

Kim heads into Sunday's free stake in first place with 69.50 points. Japan's Miki Ando, the 2007 world champion, sits in second with 57.80, and teammate Jukari Nakano is third at 57.46.

Vancouver's Mira Leung is in 10th place with a score of 45.74.
