Best method for inserting a pressure sensor in a baseball?

I misspoke there; I am simply trying to measure the grip force imparted on the ball while it is being pitched. In the study I linked in the original post, the researchers have done a pretty good job at modifying a ball that they believe behaves very similar to an original ball. I am trying to emulate that deconstructing a real ball and increasing the surface area covered by sensors if possible.
