A drill that I like to use is one that works great for infielders and outfielders alike.
He then simulates that it is a hit to his back hand side concentrating on the pivot and then a slow jog glove hand up and extended to catch the ball.
While in a slow jog the man that is next in line tosses the ball to his teammates back hand side(a throw that is catch-able but can also challenge his team mate).
The first person then catches the ball on the run back hand and has to concentrate once again on the quick stop, plant, throw using proper techniques.
Group B does the same drill only to the forehand side 5 – 10 min on each side. It is a great amount of time.
We also use this in pre-game warm-up as well, the kids enjoy it while learning!!
