You know how when you send your kid to the closet to look for something and he comes back and says, "it's not there."
That's because he's looking at the space in between himself and the item he's hunting for.
This is how I approached hitting. I saw the face of the pitcher, the hat, the fence in the background, etc. But at the same time I didn't really see any of them truly.
Once the pitcher began his stride my eyes would train in on the slot where the ball came out. At that point, it was a clear focus on the baseball.
Hope that makes sense.
