(CHICAGO, ILL.) – Welterweight Demetrius Andrade (Providence, R.I.) grabbed his second victory of the 2007 World Championships, winning a 19-3 decision over Dmitrijs Sostaks of Latvia. Lightweight Sadam Ali (Brooklyn, N.Y.) suffered the second loss for the U.S. team, dropping a 20-16 decision to Hrachik Javakhyan of Armenia in second round action on Sunday at the 2007 AIBA World Championships in Chicago, Ill. Light flyweight Luis Yanez (Duncanville, Texas) finally got the opportunity to walk to the ring for his first bout at the 2007 World Championships. Yet that is the only work out that Yanez would get as his opponent, Simanga Shiba of Swaziland, did not report to the ring for their second round contest. Shiba made weight earlier in the morning but didn’t appear at the venue for the bout. [details]
