I've always been a fan of The Inner Game of Tennis, but I found this more useful. "The Power of Now" by Eckhart Tolle won't be everyone's cup of tea as it is much derived from Buddhist teachings and not focused on sport but on life in general. However, it has seriously clued me in to ways to improve my mental game and my focus. There is a free pdf online that I found by googling.
