Aardsma-Looks like the Cubs may really have something here. He's putting up some nasty numbers and if his FB is in the mid 90's thats great. Good reports on him too. I wouldnt be in a rush to call him up because i like the pen a lot but it sure gives them some depth in case of injury or if Novoa bombs. Id be more inclined to bring him up sooner than wuertz.
