MILWAUKEE -- J.T. Snow finished his 15-year Major League career in 2006. Then he began working overtime.

Snow has filled numerous roles for the Giants in his "retirement," including radio broadcasting, tutoring Giants first basemen, serving as a roving instructor and making personal appearances on behalf of the club. He's about to acquire a new responsibility.

Snow will serve as the Giants' representative for the First-Year Player Draft, helping announce and relay word of the Giants' early-round selections.

The annual First-Year Player Draft takes place this year from June 4-6, beginning with the first round and Compensation Round A on Monday, June 4, at 4 p.m. PT. The first night of the event will be broadcast live on MLB Network and streamed live on MLB.com. Rounds 2-40 will also be streamed live on MLB.com on June 5-6.

MLB.com's coverage, sponsored by CenturyLink, will include Draft Central, the Top 100 Draft Prospects list, Draft Tracker, a live interactive application that includes a searchable database of every Draft-eligible player, and Draft Caster.

Snow, 44, spent 1997-2005 with the Giants and won four of his six Gold Glove awards for fielding excellence while playing in San Francisco. He and Hall of Famer Willie McCovey are the only Giants first basemen to start nine consectuive Opening Days since the franchise moved to San Francisco in 1958.

Tony Siegle, the Giants' senior advisor of baseball operations, will join Snow as San Francisco attempts to add to its impressive list of recent draftees (Tim Lincecum, 2006; Madison Bumgarner, 2007; Buster Posey, 2008) with the No. 20 overall pick.

Over four decades, Siegle has held front-office positions with eight different organizations. He has worked for the Giants on three separate occasions. He works with general manager Brian Sabean and the baseball operations office in waiver and rules compliance, contract negotiations, salary arbitration issues and trade discussions.
