Former Major League pitcher and mental skills coach for two of baseball's legendary franchises (the Boston Red Sox and San Francisco Giants) Bob Tewksbury takes fans inside the psychology of baseball.

In Ninety Percent Mental, Bob Tewksbury shows readers a side of the game only he can provide, given his singular background as both a longtime MLB pitcher and a mental skills coach for two of the sport's most fabled franchises, the Boston Red Sox and San Francisco Giants. Fans watching the game on television or even at the stadium don't have access to the mind games a pitcher must play in order to get through an at-bat, an inning, a game. Tewksbury explores the fascinating psychology behind baseball, such as how players use techniques of imagery, self-awareness, and strategic thinking to maximize performance, and how a pitcher's strategy changes throughout a game. He also offers an in-depth look into some of baseball's most monumental moments and intimate anecdotes from a "who's who" of the game, including legendary players who Tewksbury played with and against (such as Mark McGwire, Craig Biggio, and 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).

With Tewksbury's esoteric knowledge as a thinking-fan's player and his expertise as a "baseball whisperer", this entertaining book is perfect for any fan who wants to see the game in a way he or she has never seen it before. Ninety Percent Mental will deliver an unprecedented look at the mound games and mind games of Major League Baseball.

shirt is thin, sizing is useless
The shirt is thin but okay. The sizing is useless. I purchased a large and a medium. Each is marked with the size (L and M), but the two shirts are exactly the same size. Laid flat together or held up by the shoulders together, these two shirts are EXACTLY the same.

Fun Christmas Sweatshirt
Color: 02 Green, Size: Large
I really like this sweatshirt. It was listed as men's so I ordered the large. The sleeves are pretty long, which I really like. Otherwise it fits slightly baggy, but I typically wear a women's large so I ordered the large hoping for a little bit oversized. The material is typical for what a normal sweatshirt is, but is a little more lightweight, which I like. It being a touch thinner allows for easier layering and not peeling it off halfway through the day. The graphic is nice, the colors are bold and crisp. I love Christmas and love having tons of different themed clothing to wear, so I'm super excited to add this to my stash.

Great
This Holiday sweatshirt is great, It's made great with soft materials. It fits perfectly not tight and not bulky. It's warm and can be worn over a t-shirt or a long sleeve shirt when it's cold outside. It doesn't twist or ride up. The design is well made and looks great. The colors are bright and look nice. It's great for the holidays but after they're over I'm going to keep wearing this because I like it. It's a great price because with proper care this sweatshirt will last for a long long time.
