The Cubs should trade Ryan Dempster before his next start, according to Buster Olney. Dempster increased his scoreless innings streak to 33 on Saturday and Olney writes that dealing the right-hander now would allow Chicago to simplify their marketing of Matt Garza in late July. Last July, the Padres listened to offers for Heath Bell and Mike Adams and they couldn't get what they wanted for Bell partly because of the persistent interest in Adams.
