Glide into the fielding position - be smooth. Bend knees and keep the rear end down. Don't bend just from the waist. Field ground balls under your eyes in the middle of your body. Watch ball into glove - head and chin drop as you watch ball.
Hands give with the ball.
Don't stiff arm the ball. Keep movement going towards first as you start to raise and throw the ball. Grip ball across the seams for straighter throw. Spread index and middle finger. Thumb underneath the ball.
