“Nobody I've come across in my almost 30 years in the game did more with his God-given talent than Tewks. Not just an athlete, but a deep thinker, a good teammate and an even better friend. This book is a must read for anyone who wants an inside look into the mental aspects of baseball.”—Joe Buck, lead play-by-play broadcaster, Fox Sports
An All-Star player turned mental skills coach reveals the hidden game of baseball
Bob Tewksbury is a former Major League pitcher and All-Star who excelled on the mound in part because of his mental acuity
and resiliency. “He was one of the most thoughtful players I ever managed, approaching the craft of pitching like an artist,”
says Hall of Famer and four-time World Series Champion manager Joe Torre.
After retiring as a player and working briefly as a broadcast analyst and player development consultant, Tewksbury signed on
with the Boston Red Sox after the 2004 season to be their mental skills coach. He was with the organization for 11 years – in
2013 he was on the staff of the World Series championship team – and is currently the mental skills coach for the San
Francisco Giants, where he works with players at each level in the organization.
In Ninety Percent Mental (March 20, 2018; Da Capo Press), Tewksbury draws on his perspective
as a thinking-fan's player and his expertise as a “baseball whisperer” for an inside look at the
psychological side of the game and how a well-disciplined mind can provide a definitive edge. In
professional baseball, what separates those who succeed from those who don’t live up to their
potential is a sharp mental game both in preparation and in the heat of the moment.
This book gives fans and athletes access to the mind games a player must utilize to get through
an at-bat, an inning, and a game by sharing techniques of visualization, breathing and relaxation,
and positive self-talk. And it discusses some of the game’s key strategies and moments with
stories from legendary players who Tewksbury played with and against (Mark McGwire, Craig
Biggio, Greg Maddux), game-changing managers and executives (Joe Torre, Bruce Bochy, Brian
Sabean), and current star players (Jon Lester, Anthony Rizzo, Andrew Miller, Rich Hill).
