My Coach this year taught our team this drill. You have to divide your team up into 3 groups. The first group stands between first base and second base. The second group stands at short stop. The third groupstands at home plate. A coach and the catcher stand a little to the side of the plate. The coach hits the ball to the first group,then the first group catches it and throws it to the second group while running to the second group position. The second group girl that catches the ball throws it to home plate while running there. You just keep on rotating in all of the positions. This drill gets you in shape and alert the whole time.
