The Cubs lefty situation and other roster moves

Well I started writing this article yesterday morning and now I have to re-edit it because the Cubs have done a few things since then. My outlook today is better than it was two days ago and below will tell why.
Today the Cubs released Stephen Randolph and optioned Wil Ohman. The Cubs acquired lefty pitcher Cliff Bartosh from Cleveland yesterday for Ronald Bay. The only thing I can say about Ronald Bay is that he was named an All-star in the Arizona Fall League in 2003. Bartosh is a young lefty who struggled at times to get lefties out last year, but has potential to improve and become a good situational lefty. I was going to suggest the other day the Cubs look into John Parrish as I thought he might be a good fit if cheap, but Bartosh is a better pitcher now and has more potential than Parrish. The Cubs still have Eddie Oropesa on the roster, but he has been horrible most of the spring and is not on 40-man roster so he doesn't have much chance to make the roster.
The Cubs also made a couple other minor moves today which were all expected. The reassigned both Angel Echevarria and Calvin Murray to minor league camp and traded Cody Ransom to the Rangers for a ptbnl. It is better to get something for Ransom than just releasing him, but I was hoping some how he would impress the Cubs management and they would keep him and release Jose Macias.
