Press Release: One-third of the tickets available for WBO junior lightweight champion Joan Guzman's December 18, 2006 title defense in the Dominican Republic have already been sold. That means 6,000 of the 18,000 available seats were purchased in their first week on sale even though the challenger has not been named. "I think is fantastic and so does Guzman," manager Jose Nunez said today. "Guzman is hard at work training in Las Vegas. He is overwhelmed by this instant response. Joan is on a mission to show the world that the Dominican Republic has great boxing talent in addition to all the well-known baseball superstars." Tickets may be purchased through TicketMaster in the Dominican Republic. Nunez has set aside a "Golden Diamond Ringside" section for Dominican baseball stars.  Nunez said that the rest of the card will be filled by numerous Dominican boxers, including Guzman's brother, 130-pounder Jose Guzman and featherweight Agenis Mendez, both making their professional debuts.
