Unless Kolb proves he's a 2 inning guy, and indications are he is not really able to do that right now. (They say he's healthy, but you wonder), he's not going to come in to start the 8th. I wouldn't mind seeing a general change from the 9th inning only strategy, but you need a pitcher whose shoulder is a little more stable than Kolb's is rumored to be. I would have brought him in in the 8th, but not with the intention of letting him go two innings. I would have wanted Kolb to pitch to Vlad, Anderson, and Guillen, and then let some other scrub finish off the bottom of the order in the 9th.
