Kahn has done it again. His prose, from the unique perspective of veteran baseball writer who cares about his subjects, is at once soothing and revealing. Kahn's appreciation for the history that he witnessed - and helped create - is sure to enrich any baseball fan's appreciation of the history (to say nothing of vitally important players both on and off the field) of this great game.
