FILE - In this May 14, 2013 filephoto, a view from the upper deck stands at Wrigley Field shows the rooftop bleachers outside the right field wall along Sheffield Avenue across from the ballpark before a Chicago Cubs baseball game 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.
