HOUSTON -- Cavan Biggio, the youngest son of Astros legend Craig Biggio, is among 20 players who have been selected to play for the United States in the 2012 International Baseball Federation 18-and-under/AAA World Championships in South Korea, Aug. 30-Sept. 8.Biggio, who's entering his senior season at St. Thomas High School in Houston, was chosen from among 144 players who competed over five days at the USA Baseball national training complex earlier this month. The pool was trimmed to 28, and those players competed in the final phase of the team trials this week in California. Biggio went 4-for-8 with a double and two triples in the four qualifying games, earning him a spot in the national team. He's a left-handed hitter who plays the infield and outfield. A proud father was elated for his son to represent his country. "It's really hard to put into words, to be honest with you," Craig Biggio told MLB.com. "He's had a tremendous summer, and this is kind of the icing on the cake here where you now have an opportunity to go play as one of 20 of the best kids in the country, an opportunity to play for a gold medal with USA across your chest. To me, he's had a magical year." Cavan Biggio committed to the University of Virginia early in the summer, which was a difficult decision considering he had a chance to play with his older brother, Conor, at Notre Dame. Both played for their dad, who became coach at St. Thomas in Houston after 20 years and 3,060 hits with the Astros. "There's a lot of uniforms you're going to wear throughout the course of your life, from your high school team to summer ball, and some of these guys will put on big league uniform some day," Craig Biggio said. "But putting on a USA uniform and representing your country, to me, it doesn't get any better." The U.S. team was scheduled to play its first exhibition game Wednesday afternoon on the Cal State-Fullerton campus before departing for Taichung, Taiwan, for a three-game exhibition series with Chinese Taipei beginning Saturday. The Americans open pool play in the world championships in Seoul, South Korea, with games against Australia, Netherlands, Korea, Colombia and Venezuela. The medal games will be played Sept. 8. "I'm excited for him," Craig Biggio said. "I'm beyond words from the standpoint this is something he's going to remember for the rest of his life, the experience he's going to get with these kids. As a dad, I'm excited for him to go over there and do this and experience different cultures and the way they play the game. I'm very grateful he has a chance to be a part of it."
