According to the Trib's Paul Sullivan, Matt Murton and Rocky Cherry have been recalled from Iowa. There is no word as to who the Cubs will send down.
I'll speculate though. After being lit up last night Billy Petrick will be on his way back to Des Moines and young Jake Fox will probably join him. It's great that Lou has gotten all of these youngsters time at the big league level, but you have to wonder if Fox could contribute much at this point in his career. As the Cubs approach the dog days they are gonna need contribution from every player on the roster.
