The analytical types should find this very interesting. Tony Adams has done a pretty amazing job of analyzing the data and has it detailed down to the number of "bangs" per player.

Of the 8,274 pitches tracked there were 1,143 "bangs". It should be noted that a lack of a "bang" could indicate a pitch type so it is difficult to get an accurate assessment of the number of pitches that were foreshadowed.
Enjoy.
