Canadian Martine Dugrenier defended her gold medal in the 67-kilogram class at the world wrestling championships Friday while teammate Ohenewa Akuffo captured silver.

Dugrenier, a Montreal native, rallied to beat Elena Shalygina of Kazakhstan 0-2, 6-0, 7-0 for her second straight championship title.

"It's a lot of pressure, but I think I did quite good overall," Dugreiner said. "I lost the first period but I was able to adapt and recover the lost ground."

Ifeoma Iheanacho of Nigeria and Alla Cherkasova of Ukraine won bronze.

Akuffo, from Brampton, Ont., won a silver in the 72-kilogram class as Canada boosted its medal total at the tournament to three. Olympic champion Carol Huynh won a bronze at 48 kilograms earlier in the week.

Akuffo rallied to beat Olympic bronze medallist Kyoko Hamaguchi of Japan 0-3, 3-0, 1-0 in the semifinal.

In the final, Akuffo was shut out 1-0, 1-0 by Bulgaria's Stanka Hristova, an Olympic silver medallist and two-time world champion.

Hamaguchi and Ekaterina Bukina of Russia won the bronze medals.

On the men's side, Victor Lebedev of Russia captured his first major title, winning gold in the freestyle 55-kilogram.

Lebedev defeated Toghrul Asgarov of Azerbaijan 1-0, 0-3, 1-0.

"This time I felt myself more confident at the worlds," said Lebedev, who won a bronze medal last season. "When I won in the semifinals I promised myself that I will win the gold."

Lebedev's medal was only the second gold for Russia after five days of the competition.

Yashiro Inaba of Japan took bronze after pinning Naranbaatar Bayaraa of Mongolia in the second period of the third-place bout. Another bronze went to Frank Chamizo-Marquez of Cuba, who topped Kim Huo-sub of South Korea 1-0, 2-3, 5-1.

John Pineda of Burnaby, B.C., was 13th.

Six more men's freestyle events will be held through the weekend.
