FoxSports cited a Daily Southtown article that mentions that the Cubs are interested in trading for Barry Zito :

FoxSports.com reports that the Cubs are in talks with the Orioles for a deal that would send Prior to Baltimore and Tejada to Chicago but "talks are stalled, a source says, over the Cubs' insistence that the Orioles give up left-hander Erik Bedard along with Tejada if they want Prior – and the Cubs' refusal to include top outfield prospect Felix Pie or a top pitching prospect in return."

Both teams are also in discussions with Boston for a three-way deal that would send Manny Ramirez to the Orioles and Tejada to Chicago.
