I like this, although I would say that only two of the changes should be slam-dunks - the 5/2 and the 8/4.
With the 3 and 4 inning quality starts, the question arises whether this was actually what the team needed. 3 innings leaves 6 to cover for the pen. But in some cases, obviously, like with a spot starter, 3 scoreless innings might be getting the job done.
