I think it's unnecessary. Agreed - though I like the general concept of wanting to have our best bullets available for STL, every win we can get is important. If it's late August or September, and a sweep could get us into a tie with them or something, you might be on to something, but it's too early to think like that. If you spot start someone like Wood or Jackson, they probably won't be able to give you more than 5 innings, meaning you risk taxing the pen before the Cardinals series.
