Cubs trade Hart and Ascanio to Pirates

The Cubs traded Kevin Hart and Jose Ascanio today to the Pirates for John Grabow and Tom Gorzelanny. I don't know about this trade. If you ask me, Hart has been awfully good for this team. Three wins in three starts since the break while Dempster/Lilly were on the shelf.  And Ascanio has pretty decent stuff and seemed overall pretty competant as well. Gorzelanny, who the Cubs obtained, is a little older and has been a solid starter for the Bucs. One of those league average types that looks OK but really he only looks good because he's been on the Pirates. If he's on the Cubs he's a six or seven, only starting if multiple guys are on the DL. Basically, an older version of Hart.  Grabow is a solid lefty reliever, maybe a tick better than Marshall. That''s useful, but is that a good enough haul for the potential of Hart and Ascanio? We'll see. In the grand scheme of things, I guess you can say it's a push if not ...
