The two wrestlers recognized as the best competitors in the world at 72 kg/158.5 pounds in women's wrestling will face each other in their first match at the Olympic Games in Athens, Greece on Sunday, August 22 during the 9:30 a.m. session.    Five-time World Champion Kyoko Hamaguchi of Japan and two-time World silver medalist Toccara Montgomery of the United States were drawn into the same pool competition at their division and will wrestle right away.    The weight classes were broken into four pools, based upon a blind draw with no seeding. An athlete must win their pool in order to advance to the medal rounds.    Only the winner of each pool will advance to the semifinals on Monday, with a chance at a medal. One of these great wrestlers, Hamaguchi or Montgomery, will not win a medal at these Olympic Games.    These two stars have wrestled three times in the last year. In the World Championship finals last year in New York City, Hamaguchi beat Montgomery, 4-1. Montgomery beat Hamaguchi a month later at the World Cup in Tokyo. In the semifinals at the Olympic Testing event in Athens, Greece in early 2004, Hamaguchi won a tight 4-3 match over Montgomery.    Hamaguchi is a sports hero in her homeland. She was selected to carry Japan's flag in the Opening Ceremonies in Athens, an amazing honor for an athlete who has never been to the Olympics before. Hamaguchi's father was a famous professional wrestler in Japan. Much will be expected of Hamaguchi, and there is tremendous pressure on her to win. She is a very popular sports figure in her country.    Hamaguchi has had a strong 2004 season so far, winning a gold medal at the Olympic Testing Event in Athens, Greece as well as at the Asian Championships.     Montgomery was named 2001 FILA Women's Wrestler of the Year after winning her first silver medal. She moved up in weight after the Olympic divisions were announced in 2002. To make the U.S. team, she stopped two-time World champion Kristie Marano in the finals of the U.S. Olympic Team Trials in Indianapolis, Ind.     There is also a strong rivalry between the Japanese team and the United States team. At the World Championships in New York City, the two teams were tied in first, but Japan won the team title by tiebreaker with more champions. A month later, the U.S. upset Japan in the World Cup competition held in Tokyo, with the deciding match being Montgomery's victory over Hamaguchi. This rivalry will be tested immediately at 72 kg/158.5 lbs.    Also at 72 kg/158.5 lbs., Canada's Christine Nordhagen, a six-time World Champion who has made a comeback to compete in these Olympics, is in a pool with China's two-time World medalist Wang Xu and with Italy's Katarzyna Juszczak.
