When I heard the news last night that Mark DeRosa was retiring, I thought: There’s your new Cubs radio analyst.

Turns out I was right about him retiring to begin a postseason career in the media. However, I had the wrong outlet.

This morning, it was announced that DeRosa will be joining MLB Network’s stable of analysts.

The official release contained this quote: “While I still had the opportunity to return as a player, it became clear to me that the chance to begin a career at MLB Network was too good to pass up, and I am very excited to get started,” said DeRosa.

It’s a good move for DeRosa and MLB Network. Not so good for the Cubs.

DeRosa would have been high on the Cubs’ wish list to replace the departing Keith Moreland on WGN-AM 720. He was the first potential candidate mentioned yesterday in a story by Paul Sullivan in the Chicago Tribune.

Since Moreland’s decision not to come back was a surprise, the Cubs and WGN are just now putting together their lists.

From Sullivan’s story:

(Pat) Hughes, coming off hernia surgery, said he’d prefer “someone who likes to have fun, is insightful, has a sense of humor and is a team player, similar to Keith.”

(WGN sports director Dave Eanet) said the hire would not necessarily have to be a former Cub, pointing to Deshaies and Brenly.

“Is it good to have a connection to the Cubs? Yeah,” he said. “Is it a necessity? Not if we get the right person. Having chemistry with Pat is important.”
