Brenly has been in the Cubs booth since 2005 and called his time in Chicago "the experience of a lifetime ... as much ridiculous fun as humanly possible." Brenly added that he was "grateful for the chance and the joy of working at Wrigley Field."
Brenly is expected to replace Mark Grace in the Diamondbacks' TV booth, as Grace was placed on leave after a DUI arrest. Brenly managed the Diamondbacks from 2001 through 2004, was their manager for their lone World Series championship and still has a home in Phoenix.
Cubs play-by-play announcer Len Kasper was saddened to see Brenly leave Chicago, but "eternally grateful" for their eight years together.
Grace is one of the many candidates who is being considered as Brenly's replacement in Chicago. Several analysts are rumored to be interested in the job. Kasper said no matter who replaces Brenly, "Bob's stamp on our booth and our broadcasts is a permanent one."
