Use whatever pitches you feel comfortable with, knowing that a heavy ball will have some late movement to it.
Just to give an example, I was a guy who was known for a heavy ball, and was primarily a sinker/slider pticher, but used a 4 seam on the corners in counts that were to my favor. The late tailng action of the 4 seamer made guys chase the outside pitch and handcuffed them with the inside pitch that I would start at the thigh. This also caused them to get jammed, which is something that never feels good against heavy armed guy. Plus, the 4-seamer gave them another thing to look for and think about, as the movement was in a different plane than my 2 seam and slider.
In short, its a good thing, that you really dont need to put much thought into; it is what it is. Use the pitches that you’re comfortable and most successful with.
Great article by the way, Spencer- thanks for sharing!
