Ninety-Percent-MentalBook Overview:

In Ninety Percent Mental, Bob Tewksbury provides readers with a unique insight into the game of baseball. His unique to industry background as both a longtime MLB pitcher and a mental skills coach for two of  baseball’s most successful franchises, the Boston Red Sox and San Francisco Giants, give Bob a special edge when it comes to providing knowledge and education in the area. The legendary player gives readers access to the mind games a pitcher must play in order to get through an at-bat, an inning, and a game.

In the book, Tewksbury also explores the fascinating psychology behind baseball, including how players use techniques of imagery, self-awareness, and strategic thinking to maximize their performance. He even gives you a peak behind the curtain into how a pitcher’s strategy can change throughout a single game. He also offers an in-depth, personal look into some of baseball’s most monumental moments, plus intimate anecdotes from ‘A-listers’ of the game, including players who Tewksbury played alongside and against, game-changing managers and executives, as well as current star players.

With Tewksbury’s unique and special expertise in the game, this entertaining and insightful book is perfect for any fan who wants to understand the game in a way they have never been able to before. Ninety Percent Mental will deliver an unprecedented look at the on-field and off-field games of Major League Baseball.

Why We Recommended It: At Athlete Assessments we love this book not only because it was written by one of our clients, but because it provides an insider’s perspective on the array of mental challenges that professional baseball players face throughout every step of their careers. From rookie to pro, to mental skills coach, we’re given a fantastic behind the scenes look into Tewksbury’s career, from player on the pitch through to performance coach on the sidelines.
