If you're involved in Little League, then one or both of these books will probably become an essential part of your library. Little League Drills and Strategies and Managing Little League Baseball were both written by Ned McIntosh, a father who coached three sons in Little League Baseball over the course of 20 years.
Both books are in their 3rd printing, which gives you some clue to their popularity over the years. The book on drills and strategies is great for any parent that is involved with Little League. The instructions are clear, many of the drills have well designed diagrams, and photographs help make the author's point in many parts of the book. The only element that I would have liked to see updated are the photos. Most of the photographs are well done, however, a few of them are too light and washed out. This however, is a small admonition to the layout artist. For the most part this book is well organized, and easy to follow.
After the sections on the various baseball drills for the kids, there is a section on "Strategy for Working With Parents." Although this is written for coaches working with parents, I think that parents should also read this for strategies for working with coaches. My son was in a number of teams when he was in elementary school and junior high school, and a few times the coaches were disorganized, or not as ethical as I would have liked. If I had read this book back then, I think I would have had a few tools at my disposal that would have helped get things back on track.
The companion book, Managing Little League Baseball is surprising full of more drills. At times it seems as though there are actually more drills in this book than the Little League Drills and Strategies book, however the drills book goes into much more depth on the drill techniques.
If you're a coach, these books will help you organize your practices for your players, give you a better understanding of new Little League rules, and help you organize the parents. If you're a parent, the books will help you understand the drills your kids will be practicing, and help you work more efficiently with the coach. Both books are well worth a thorough reading.
