Press Release: American middleweight Shawn Estrada earned his second victory at the Americas Qualifier in Guatemala City, Guatemala on Sunday, defeating Colombia’s Alexander Brand, 13-2. The victory advances Estrada to the semifinal round where he will face Brazil’s Yamaguchi Florentino on Tuesday. A semifinal win will earn Estrada a berth in the 2008 Olympic Games in Beijing, China. Estrada held a slim 3-1 edge after the opening two minutes of boxing. He picked up the pace in the second stanza, more than doubling his point total to move out to an 8-2 advantage at the halfway mark of the bout. Estrada kept his defense tight over the final four minutes, holding Brand scoreless through the last two rounds. Super heavyweight Michael Hunter (Las Vegas, Nev.) will face Canada’s Didier Bence in quarterfinal action late on Sunday night. He will need two victories to claim an Olympic berth.
