From CBS Sports:

 Poreda going into White Sox rotation

Aaron Poreda, SP CHW News: The Chicago Sun-Times reports that Aaron Poreda will be added to the major league roster Tuesday, likely taking Barolo Colon's spot in the starting rotation. Poreda is 5-4 with a 2.38 ERA in 11 starts (64 1/3 innings) for Double-A Birmingham. Analysis: Manager Ozzie Guillen admitted on Monday that he and general manager Ken Williams had a lengthy meeting before the first game of the doubleheader with Detroit to discuss different scenarios, and with the Jake Peavy deal falling flat, as well as Colon's struggles - possibly health related, Guillen hinted - had no choice but to go with their best prospect in Poreda. He has excellent strikeout ability (69 K's in 64 innings), but is going to be making a big jump from Double-A to the majors. Take a flier on him in any AL-only league for his upside and in larger mixed leagues, though, we would not recommend starting him until he can prove effective at this level.

First Hanson, now Poreda. Good week for me.  :)  I'm very interested to see how he handles the jump. I'm guessing some early struggles, but then stabalizes after the All Star break for a decent 2nd half. Long-term, I like his potential!
