"Tewks and I were teammates when Tewks was ending his career with the Twins. I saw him use his mind to be successful on the mound. Years later, we were once again on the same team with the 2013 World Series champion Red Sox, and I again saw him use his mind--this time to help others. I know he helped us win, and I know this book can help anyone who reads it."—David Ortiz, 10-time All-Star, 3-time World Series champion, and New York Times bestselling author of Big Papi: My Story of Big Dreams and Big Hits; called "the most important player in Boston Red Sox history."
