CHICAGO (CBS) — There’s a new wrinkle in the Cubs’ attempt to find new revenue at Wrigley, and it could change the look of the friendly confines forever, reports WBBM’s George Offman.

The Chicago Cubs want a new Jumbotron for Wrigley Field and 44th ward Alderman Tom Tunney is apparently all for it. But sources tell WBBM he wants the new digital scoreboard in center field so as not to block the rooftop owners.

Sources also say the current iconic hand-operated scoreboard would be moved to left center field.

The Cubs, who want the scoreboard as another way to generate revenue inside the ballpark, want the Jumbotron in left field and consider other proposals as a non starter in negotiations with Tunney and the city.

The Cubs want a resolution by April 1, a date they have implied as a deadline to conclude negotiations.
