CHICAGO -- Analyst Keith Moreland is leaving the Cubs' radio broadcast booth to spend more time with his family, WGN Radio announced Wednesday.

Moreland wrote a note to WGN Radio staff, thanking the fans, his colleagues and the Cubs for the opportunity.

"After spending three years doing it, I've simply decided that I want to spend more time at home in Texas," Moreland said in his note.

Moreland, who played for the Cubs from 1982-87, joined play-by-play broadcaster Pat Hughes for the 2011 season, replacing popular Ron Santo, who was in the booth from 1990-2010. Santo died in December 2010.

Moreland, 59, known as "Zonk," played 12 seasons with the Phillies, Cubs, Padres, Tigers and Orioles, and he won a World Series in 1980 with Philadelphia.

"He was fun to be around, insightful and a team player," Hughes said of Moreland in a statement. "Like our listeners, I feel like I learned a little more about baseball each day from him. I wish Keith all the best, and I will miss him greatly."

After his playing career ended, Moreland spent 16 seasons as the University of Texas baseball color analyst and nine seasons as the Longhorns' football color analyst.
