The five-athlete U.S. team competing at the Takhti Cup in Tehran, Iran, Feb. 20 completed the competition without winning any medals.    Three athletes were defeated in the quarterfinal round and eliminated from medal contention: 1998 World Champion Sammie Henson (West Point, N.Y./Sunkist Kids) at 55 kg/121 lbs., Mike Mena (Bloomington, Ind./New York AC) at 55 kg/121 lbs. and Joe Heskett (Grover Beach, Calif./Gator WC)  at 74 kg/163 lbs.    Henson had won his pool competition on Thursday, but was eliminated in a bout Friday morning against an opponent from Turkey, 5-4. U.S. coach John Peterson questioned the officiating of the match, and felt that Henson should have been awarded the victory.    "The Iranian fans where chanting USA, USA, USA at the end of the match, knowing that he really had won," said Peterson. "He did make some mistakes that forced him to try to come from behind. The Turk scored on a leg attack which Sammie tried to counter, bringing himself to his own back. The score at the end of one period was 4-0."    "Sammie scored a quick takedown and then had back points with guts that they refused to give," said Peterson. "The Turk took several very long breaks, with no attempt by the referee to get him to wrestle and no passivity call."    Mena won his first match of the day, a 4-1 victory over B. Mohammadze of Iran, which clinched him the victory in his pool. In the quarterfinals, he was defeated by an opponent from Mongolia, 6-0. The athlete from Mongolia eventually won the gold medal in the tournament.    Heskett also had one pool match to wrestle on Friday morning, scoring an 11-0 technical fall over an opponent from Afghanistan. In the quarterfinals, he was defeated by Sadeqnedjad of Iran, 3-1.    The other U.S. wrestler who competed on Friday, Yero Washington (Colorado Springs, Colo./Sunkist Kids), lost in his pool competition at 60 kg/132 lbs. In his only bout of the day, Washington fell to B. Akhoundi of Iran, 6-1.    The other U.S. wrestler on the tour, Ramico Blackmon (Colorado Springs, Colo./Team Excel) was eliminated on Thursday with a 1-1 record at 74 kg/163 lbs.    More complete results from the competition will be posted when available.    This was the fifth time that USA Wrestling has participated in the Takhti Cup, with U.S. teams participating in 1998, 2000, 2001 and 2003. The United States wrestling team was the first U.S. sports team to compete in Iran after the Iranian revolution when the team competed in the 1998 Takhti Cup. The U.S. also competed in the 1998 World Freestyle Championships held in Iran.    Teams from Iran have also competed in the United States on numerous occasions during the last decade. These sports competitions have been held even though there are no diplomatic relations between the two countries.
