The United States won four of their five bouts in the first session of women's freestyle wrestling at the Ano Liossia Olympic Hall in Athens, Greece, Sunday, August 22.     Women's wrestling is the newest sport in the Summer Olympic Games, and this was a historic day for the sport.    The United States opened with an impressive start, when 2003 World silver medalist Sara McMann (Colorado Springs, Colo./Sunkist Kids) pinned 2001 World Champion Lili Meng of China in the first period at 63 kg/138.75 lbs., at 2:01    McMann scored the first two points with a tilt from the mat after Meng was hit with a passivity call. With the athletes back on their feet, McMann countered a Meng attack, stepping over and putting Meng to her back. McMann pressed down and scored the fall.    It was the first pin in the history of women's wrestling in the Olympic Games, one of the many milestones that will be set     The other athlete in McMann's pool draw is Canada's Viola Yanik, a 2003 World bronze medalist, who she will face in the 5:30 p.m. session on Sunday.    The U.S. won their next two matches that were held at the same time on the mats. Patricia Miranda (Colorado Springs, Colo./Dave Schultz WC) at 48 kg/105.5 lbs. and Tela O'Donnell (Colorado Springs, Colo./Dave Schultz WC) at 55 kg/121 lbs. scored opening wins in very exciting bouts.    In her opening bout, Miranda stopped 2003 World bronze medalist Li Hui of China, 8-5.  The first period was very close, with Miranda scoring late in the period to take a 5-4 lead at the break. In the second period, Miranda was able to turn Hui for exposure points and win the match.    Miranda is in a pool of four athletes, so she had another match later in the morning session.    O'Donnell started slowly against 1996 World champion Olga Smirnova of Russia, falling behind 5-0 after the first period. In the second period, O'Donnell scored a crotch lift counter from her feet, and caught Smirnova on her back, scoring a pin in 4:26.    The other athlete in O'Donnell's pool is Tonya Verbeek of Canada, an athlete who defeated O'Donnell at the 2004 Titan Games in Atlanta, Ga. in June. They will compete during the 5:30 p.m. session on Sunday.    The United States dropped its first match of the day when five-time World Champion Kyoko Hamaguchi of Japan stopped two-time World silver medalist Toccara Montgomery (Cleveland, Ohio/New York AC), 8-4 at 72 kg/158.5 lbs. It was a rematch of the 2003 World Championships finals, won by Hamaguchi.    Hamaguchi scored first and led the entire bout. Hamaguchi was able to turn Montgomery early in the match for exposure points. After the first period, Hamaguchi's lead was 5-2. Although Montgomery scored some takedowns in the second period, Hamaguchi continued to score from her feet as well and added three more second-period points for the 8-5 win.    The other athlete in Montgomery's pool draw is Stanka Zlateva of Bulgaria, who Montgomery will face in the 5:30 p.m. session    The final U.S. match of the session was a 7-3 victory by Miranda over Lorisa Oorzhak of Russia at 48 kg/105.5 lbs.     Oorzhak opened the match with a 2-0 lead after the first period, but Miranda came back strong in the second period. After a takedown to close the score to 2-1, Miranda was able to turn Oorzhak twice from the top. She received two points for exposure and an additional backpoint for holding Oorzhak on her back, getting three points out of each move for a 7-2 lead. A late Oorzhak takedown ended the match at 7-3.    Miranda still has one more match left in her pool. She will face Mayelis Caripa of Venezuela in the 5:30 p.m. session.    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.    There will be a fifth-place match at each weight class, so the athletes who are second in their pools enter a repechage, but are not eligible to claim a medal.    All four U.S. wrestlers will compete in the second session of Sunday's action at 5:30 p.m. This round will determine which athletes will advance to Monday's semifinals.    A total of 50 wrestlers weighed in for the first Olympic Games women's wrestling tournament in history.
