The Chicago Cubs are going to look, and sound, a lot different in 2021.

Longtime TV play-by-play man Len Kasper will no longer call Cubs games after 16 seasons as he heads to the South Side to serve as the play-by-play radio voice for the Chicago White Sox, the team announced.

"Broadcasting baseball on the radio has always been my dream," Kasper said in a statement, according to Daryl Van Schouwen of the Chicago Sun-Times. "I am happy the White Sox were interested in having me handle their play-by-play responsibilities, and I am appreciative that the Cubs were willing to let me leave that organization on such great terms.

"I have always been fascinated by the creative freedom radio allows its broadcasters, and baseball is such a great game when presented on the radio. I have been dreaming about doing this since I was 12 years old, listening to Ernie Harwell, and I didn't want my career to pass without experiencing this great game nightly from the radio booth. I want to thank both the Sox and Cubs for allowing me to live out this baseball dream."

Kasper began calling Cubs games in 2005. Chris Myers is the leading candidate to replace him, according to Sharma.
