FILE - This May 17, 2013 file photo shows spectators watching a Chicago Cubs baseball game from several of the rooftop bleachers across the field from Wrigley Field in Chicago. The owners of the Chicago Cubs say they’re moving forward with plans to renovate and expand Wrigley Field, despite the threat of lawsuits by the owners of the adjacent rooftop venues overlooking the 100-year-old ballpark. Chairman Tom Ricketts, whose family owns the north-side Chicago team, said Thursday, May 22, 2014, that the Cubs will submit a revised expansion plan to the Commission on Chicago Landmarks that includes the team’s original proposal to add several outfield signs and additional bleacher seats.
