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!

I purchased it for my grandson for Christmas. He is 10 years old and is having difficulty reading it at his reading level. He is saving it for when he is a little older Otherwise, the book would probably be suitable for a teenager and older.

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.

Great book on the importance of pitchers, and all athletes, addressing the mental aspect of their sport. The mental part of the game supports the physical part

I already wrote a very favorable review for this book. I really couldn't have written a better one. Trouble is, I've read a few books after this one and can't remember what all I wrote. Shame on Amazon for losing my 5 star review. All I can say is, if you love baseball & are open to Tewks insights from experience and higher education, it's a must for you and any player from 10 years old to and including the majors! I also love the insights on how to make my every day life better.Very well done! Good life lessons and humor.

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.

This is such a great read. I'm so excited that Bob Tewksbury took the time to put into book form what he apparently has been doing for a successful career now. How can you argue with a guy who worked with the championship Red Sox teams?! Anyway... I don't coach or play the sport of baseball. I got a lot of good takeaways from this book for my everyday life and my work as a manager in my 9-5 job.

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.

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 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.

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.

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