This is Hughes' 16th season as WGN Radio's play-by-play announcer. Santo's last season as the team's analyst was 2010. The former Cubs third baseman, who died last December, began his broadcasting career in 1990 and teamed with Hughes for 15 seasons.
Fans can cast their votes for the Cubs' radio broadcasters at the Hall of Fame's Facebook page, www.facebook.com/baseballhall. This is the ninth consecutive year fans will select three of the 10 names on the ballot for the Frick Award.
Voting runs from Thursday through Sept. 30, and fans can cast votes once per day through September.
The Hall of Fame has trimmed the list of fan-eligible candidates to 75, with two representing every current big league team and 15 at-large selections. The selections were based on popularity, longevity and past voting results in the online fan balloting. Eligible candidates must have a minimum of 10 years of continuous Major League broadcast service with a ballclub, network or a combination of the two.
Results of the fan voting will be announced Oct. 5. The final 2012 Frick Award ballot will be comprised of the three fan selections, along with seven other candidates, determined by a Hall of Fame staff research team. The winner will be announced on Dec. 6 at the Winter Meetings.
