Here is one of the best infield drills I have used. It is simply called turn two. We use the infielders at their normal position. We place two at each spot except pitcher, one in position and the other backing up. The outfielders are the hitters. Place a batting-T at home plate and the infielders have to hit a ground ball and sprint to first. The object of the game is to get the out at first or the hitter gets credit for a run and clears the base. There are no other base runners. If you make it to first you are safe and it counts as a run. If the defense can turn a phantom double play, they get to subtract a run. The goal is to play for about 15 minutes and challenge the defense to keep the outfielders to a zero score. If a player makes an error, the fielder backing him up takes over until he commits am error. Any ball that travels in the air beyond the infield arc is an automatic out. This is a great way for the infielders to get a lot of ground ball work under pressure. It forces them to determine when they can go for the double play and when they must take the out at first. You can also play in teams of four or five and the hitting team gets nine outs.
P.s. kdog, I would love your power point as well. Thanks.
