Ninety Percent Mental: An All-Star Player Turned Mental Skills Coach Reveals the Hidden Game of Baseball

Great book by a great person having a tremendous influence on the baseball world. As someone who works in the sport psychology world and loves baseball, I've read just about everything there is on the topic. Although I looked forward to the book, it made me wonder what Tewks would do for his approach to bring something new to the table. Well, he found a great way to do so with his writing style and format of the book. Tewks weaves the story of his baseball career with that of his career as a mental skills coach in a way that offers really interesting stories and provides valuable content regardless of whether you're reading as a player or coach. He is very open in giving some of his signature techniques with players but making it very clear the relationships you build trump any skill- it's about the people. The book is well written and easy to read. No matter your existing knowledge of the mental side, I think you'll find it both enjoyable and valuable. Well done by Tewks!

Entertaining read from beginning to end, but the real value for me was found in the mental approach and preparation to being a competitor. Both of my teenage kids play 2 sports each and I coach them regularly. This book has given me great insight into leading them both through slumps and performance struggles. It has given me a “language” to communicate with as a coach and parent. It’s not just about talent or even training. Thanks Bob for giving us a glimpse into your life and the world of pro baseball.

The author has worked as a baseball psychologist. Though most baseball players would probably frown on seeing a psychologist, most would agree that base is a large part mental. I found it very interesting. The author also played in the major leagues, which makes even more credible.

I bought this book to better understand what my son, a baseball player, is experiencing. I found it a helpful and easy read.

Truly impactful book written by a very cerebral pitcher who knows the game inside and out, but has the ability to break it down so it can be understood by all. Novices to experts and everyone in between who wants to get to know the game will appreciate this.

The author gave us a nice review of his pitching career and I had forgotten his background. Obviously after that his citations of how different hurlers approached various hitters (or how he did himself) was of interest. But after a lot of these mental approaches to pitching were featured, the book seemed to become a bit repetitious. In fact so much so that I never did finish it! Probably a good book for a high school, perhaps even a college coach to share with members of their pitching staffs so that they might see how the pros approach pitching.

First off let me disclose that I know and like Bob Tewksbury. I want to be above board here. With that said, I loved this book. I bought 3 more copies, two for young baseball players I know and one for my daughter, an ice hockey player. This book is not only great, but it will make you think about your sport. The info inside about breathing, slowing things down and positive self talk are invaluable. I'd put it in the "must read" category for athletes or, parents.

Grandson plays baseballlo ex this book.

Great book on the mental side of coaching baseball. As a coach of multiple sports, it also goes beyond just baseball coaching. With personal insights that add to the info it’s worth the read.

I loved this book. Having relied upon my mental skills as a football player, I appreciated hearing how professional athletes rely on their mental skills to achieve their success. Although Tewks talks about his baseball career, the principals he describes apply to almost any sport. Visioning, positive self talk, mental routines and anchor statements are key to success on the field of play and in life. Great job!

Great inside view of pitch selection and the thought process behind it.

Enjoyed it very much and I'll be applying it in other areas than baseball. Very well written and nice balance of advice and baseball stories.

This book was a quick and easy read. Happy to purchase and to read highly recommended for the student or athlete looking to improve their quality of their game.
