HOUSTON -- Craig Biggio will forever be revered as one of the greatest players -- if not the greatest player -- in franchise history, so it goes without saying that the former second baseman -- with no disrespect to Lance Berkman -- is also the best first-round Draft selection the Astros have made.

For that reason, it's only fitting that Biggio will represent the Astros during this year's First-Year Player Draft. Former stars and Hall of Famers from all 30 teams will gather at the MLB Network Studios to open the three-day Draft with the announcement of the first-round selections.

The Astros' first pick this year will be No. 21 overall.

MLB.com will offer live coverage and analysis of the entire First-Year Player Draft on June 9-11. The MLB Network will broadcast the first round beginning at 5 p.m. CT on June 9 from its Studio 42, and those 32 selections also will be simulcast live on MLB.com.

Beginning with the 33rd pick, up-to-the-minute on-air coverage from the remaining rounds will shift exclusively to MLB.com/Live, where host Vinny Micucci will be joined by MLB.com Draft expert Jonathan Mayo and Major League Scouting Bureau director Frank Marcos.

Once the first night is done, the Draft will continue with the rounds 4-30, via conference call from MLB Headquarters in New York, at noon on Wednesday, June 10. Rounds 31-50 will be on Thursday, June 11, starting at 11:30 a.m.

Biggio was taken as the 22nd pick overall in the 1987 Draft and went on have a Hall of Fame caliber career, becoming the 27th player in history to record 3,000 hits. He also topped the franchise record books with 2,850 games played, 1,844 runs scored, 668 doubles, 1,014 extra-base hits and 4,711 total bases.

Biggio ended his career with 3,060 hits, 20th all-time. He was named to a franchise-record seven National League All-Star teams, and he received five Silver Slugger Awards. He also received four Rawlings Gold Glove Awards.

Biggio, who retired after the 2007 season, is currently in his second year as a special assistant to general manager Ed Wade.
