This is from a relatively well pitched CPU vs. CPU game with lots of contact and as such it might not be as illuminating, but as you see there are quite a few misses in the strike zone:
It might be your approach that might be causing CPU to make lots of contact. I'm curious what your pitch breakdown looks like... (that is if you are so inclined to look at this sort of thing).
I know a lot of human players throws too many strikes, and if you (or CPU) can expect to see stuff in the strike zone most of the time, making contact isn't probably all that hard. I wonder the same kind of thing is happening with you.
