Harry Tanamor W Luis Yanez... Thursday's evening session as the Amateur world championships was not kind to the United States, as its boxers lost three out of four bouts.  Pan Am gold medalist Luis Yanez's loss to Filippino Harry Tanamor was probably the biggest surprise. Tanamor claimed the early lead, a 6-2 margin after the first round, and he increased it little by little every round. Yanez, who reserved a spot in next year's Olympics, came out charging in the fourth round, but Tanamor never stopped circling the ring and went on to win the 17-7 decision.

Sergey Vodopyanov W Gary Russell... Bantamweight Gary Russell, Jr. dropped a quarterfinal bout by a 16-6 count to Russia’s Sergey Vodopyanov. Like Yanez, Russell is going to Beijing next year, but this match was an example of Russia's emerging dominance at these games. 

Demetrius Andrade W Jack Culcay-Keth... One of America's few highlights on Thursday night was welterweight Demetrius Andrade, who moved on to the semifinal round with a 30-9 win over Germany’s Jack Culcay-Keth. He never trailed in the bout and landed strong punches that caused the German to receive a standing eight count in the third round.

Islam Timurziev W Michael Hunter... The most painful loss of the evening went to Michael Hunter, who needed a win to qualify for the Olympics. Hunter landed some good punches, but it was not enough to defeat Russia's Islam Timurziev.  Timurziev dominated the second and third rounds, and while Hunter fought aggressively in the fourth, the best he could do was an even round. Timurziev had his hand raised after a 22-15 decision.

Matvey Korobov W Jianzheng Wang... The leader of this tournament's Russian dominance is Matvey Korobov, who is defending the middleweight world championship he won two years ago. Korobov advanced to the semifinals with a commanding victory over Jianzheng Wang of China, 22-3. The best match-up of these games could materialize between Koborov and Bakhtiyar Artayev of Kazakhstan, the 2004 Olympic welterweight gold medalist who has moved up to middleweight. If both men win today, there will be a champion vs. champion clash in the middleweight finals.
