A dazed and teary Ivica Kostelic embraced his sister at the finish after putting an unmistakable family stamp on the Alpine skiing world championships.

The Croat won the slalom today to join sister Janica in making skiing history and denying Bode Miller of the United States a shot at a third gold medal. Miller finished sixth and completed the two-week event with three medals.

This was Ivica Kostelic's first major title and the first time a brother and sister won the same event at a world championship. Janica took the combined last week and the slalom Saturday.

Silvan Zurbriggen of Switzerland won the silver today and Giorgio Rocca of Italy took the bronze. After Miller, the top Americans were Chip Knight (11th), Tom Rothrock (12th) and Erick Schlopy (15th).

Ivica Kostelic dawdled at the finish line, then dropped to his knees.

"I couldn't help shedding a tear at the finish because it was a great day for me," he said.

Janica said she was "terribly nervous" watching the race.

"I could no longer stand on my feet so I just knelt down," she said.

Austria led the world championships with nine medals, but like Croatia had three golds.

"It's pretty cool to be on top with Austria," Ivica said. "We are a country without much snow, but I guess we're pretty good."

The 23-year-old Croat covered the relatively flat Corviglia course in a combined time of 1 minute 40.66 seconds. Zurbriggen rallied from seventh and finished 0.33 of a second behind. Rocca was 0.36 back.

Ivica Kostelic has skied in the considerable shadow of his 21-year-old sister. Janica easily won two golds before Ivica's race and at last year's Olympics finished with three golds and a silver.

"Janica is a very big inspiration for me and her medals motivated me," Ivica said. "She has always given me advice. Only it's easy for a champion to give advice."

Miller earlier won the giant slalom, the combined and a silver in the super giant slalom. He was trying to become the first American to earn four medals at a world championship.

He lost his left pole midway down the course in the first run, leaving him with 0.90 seconds to make up. His second heat also was rocky, but he climbed two places to sixth.

"I lost a lot of time in the first run," he said.

Ivica Kostelic wins the slalom, joining sister Janica as first siblings to win the same event at a world championship.
