The Cubs announced Thursday that Kasper received a contract extension and will remain as the team's television play-by-play broadcaster through the 2011 season.
"I am thrilled to extend what has been, for me, an incredible relationship with the Cubs, WGN, Comcast SportsNet and my partner Bob Brenly," Kasper said. "It's an honor to announce games with Bob for the greatest fans in sports, and I look forward to calling many exciting Cubs' seasons to come. My family and I are very proud to call Chicago our home, and there's no better place to broadcast big league baseball than Wrigley Field."
The 2009 season will be Kasper's fifth with the Cubs. He joined the team in 2005 after three seasons of television play-by-play for the Florida Marlins.
"Len has emerged as an industry star, and we're excited about having him and Bob Brenly in the Cubs broadcast booth for years to come," said Mike Lufrano, Cubs senior vice president.
Brenly is signed with the Cubs through 2012.
The upcoming season will mark Kasper's 11th doing play-by-play in the Major Leagues. He began his big league career broadcasting select games for the Milwaukee Brewers from 1999-2001.
