We have an idea of what each pitcher was throwing and from where, so let's see what it looked like. So we can take a look at the flight-paths of each relief pitcher's pitches (thanks to BrooksBaseball.net). There are two graphs for each pitcher. The first is a bird's eye view showing how the pitch moves from left to right as it moves toward the plate. The second is the side-view that shows the vertical movement.
We'll go by game by game, and only look at Nelson's second appearance because it offers a bigger sample (14 pitches rather than 10).
