Jenny Wong (Colorado Springs, Colo./Sunkist Kids) captured a silver medal at 51 kg/112.25 pounds, on the first day of medal competition at the Yarygin Memorial International in Krasnoyarsk, Russia, Feb. 1.    After capturing her pool competition on Friday, Wong opened up today's action with a 12-1 technical fall over Elena Andrieva of Russia in the semifinals. Wong was ahead in the gold-medal finals by a 5-0 margin, before she was caught and pinned by Elena Tolstenko of Russia at the 5:06 mark.    Wong, who is the No. 1 U.S. athlete at 112.25 pounds, won all of her preliminary bouts by pin or technical fall.    "Jenny really turned a corner here at this event," said U.S. coach Rusty Davidson. "When you wrestle quality like Tolstenko, you just can't make a mistake."     Three U.S. wrestlers were undefeated on their first day of action and advanced from their pool competition: Patricia Miranda (Colorado Springs, Colo./Dave Schultz WC) at 48 kg/105.5 pounds, Sara McMann (Colorado Springs, Colo./Sunkist Kids) at 63 kg/138.75 pounds and Iris Smith (Fort Carson, Colo./U.S. Army) at 72 kg/158.5 pounds.    Miranda won her first two bouts, a 4-1 decision over Lilia Kaskarakova of Russia and a 7-1 decision over Irina Merleni of Greece. Miranda, a 2000 World silver medalist, was a member of the 2002 U.S. Women's World Team.    McMann had three strong victories. She opened with an 11-3 win over Ludmila Golovchenko of Ukraine. Her next two wins were dominant, a 3:28 pin over Kristina Odrina of Latvia and a 10-0 technical fall over Olga Khilko of Bulgaria. McMann has competed in three straight World Championships for the United States.    Smith also scored three wins. She opened with a 3-0 victory over Karina Shedoyan of Russia, then stopped Svetlana Mikailina of Russia, 7-0. Her third match was a 7-6 battle over Anastasis Deshneva of Greece, which Smith won on a last-second reversal. Smith is a two-time U.S. World Team member.    The only U.S. athlete to suffer a loss in the pool competition today was 2002 World silver medalist Tina Wilson at 55 kg/121 pounds. Wilson won her first bout with a 5-2 decision over Naidan Otgonzhargal of Mongolia. In her second bout, Wilson was defeated in overtime by veteran Russian star Natalia Karamchakova, 3-1.    "It was a great day for U.S. women's wrestling," said Davidson. "It's easy to see the impact our resident program has had in its first six months.  Our future is very bright."    Information on the men's competition will be posted when it is received.
