There are two kinds of focus in vision peripheral vision and focal vision. Soft Focus on the pitchers head and shoulder area. Don't stare because if you hard focus too early it is hard to pick up the ball, and only hard focus once you see the ball in the air.
Picking the ball up out of the hand is a good goal but in reality it will take at least 10 feet in flight to pick it up, I once read that basically the first and last third of ball flight are blind and most of the information comes from the middle third of the ball flight.
