Perhaps if there were very large increases at the whole innings and nearly zero values at the partial inning marks, it might lend some credence to that theory. But what we see is a small, but statistically significant, increase in starters going a whole number of innings. This means that NL managers consider pulling their starter early for a pinch hitter, or stretching them to the end of an inning, but they don’t automatically implement that strategy. It means that there is yet another factor for NL managers to weigh – does the risk of keeping a fatigued starter in outweigh the benefit of not using an extra reliever for only a partial inning, or does the benefit of using a pinch hitter outweigh the cost of using extra innings from the bullpen and “wasting” a starter that might go a few more batters or innings?

These are factors that the NL manager must consider in addition to how the pitcher feels, how effective he’s been, and the other factors that an AL manager must also consider. Whenever you’re adding additional factors for the manager to weigh in making his decision, you’re increasing his strategic choices, not decreasing them.

I realize that doing a double switch is not always an option, if the manager doesn't want to take out any of the position players at that point in the game. But it's still part of the NL strategy (and interleague and World Series strategy for AL teams playing in NL parks).

In the NL, the decision of taking out a pitcher is heavily influenced by his spot in the order, and is usually the deciding factor. AL managers don't have that luxury.
