Chicago Cubs chairman Tom Ricketts hopes to get approval by next month from the City of Chicago to move ahead in the fall on the five-year renovation plan of Wrigley Field. "There are a handful of issues," Ricketts said Wednesday from the site for the Cubs' new spring training facility. "We are just working them out with the Alderman (Tom Tunney) and working them out with (Mayor Rahm Emanuel). We are hopeful we will get some resolutions soon. If at some point we are going to be in the ground (starting the project) in October, we have to get to some resolution in the next few weeks."
