We've used a variation of this since last spring. I'd give credit where it's due but don't remember where I pulled this from as it's saved in a word file.
quote:
When we take the field on defense, we have the third base-man and shortstop take a ball with them to their positions. The third baseman takes three steps to his right with the ball in his glove and simulates a backhand play. He fires the ball to the second baseman who relays the throw to first. The first baseman keeps the ball. The shortstop, with ball in his glove, takes three steps to his right and also simulates a backhand and throws the ball to second base which is turned for a double play. The first baseman immediately turns and throws the ball back to the second baseman and keeps the other ball in his glove.
Now the second baseman goes backhand three steps to his right with the ball in his glove and flip feeds the ball to the shortstop who turns it and fires the ball to first base. Now the first baseman comes off the bag and simulates a backhand play and fires the ball to the shortstop covering second who then fires it back to first base. The first baseman then fires the two balls he has in his glove back to the third baseman and shortstop to start the process all over again.
