The author does physics modeling right, always conscious of error, weighing the statements of the players themselves. Near the end he dips into statistics, and for that I'd rather read Bill James.
A thorough discussion of several topics for pitching and hitting. The difference stitching makes on pitched and batted balls. Solid reasons why the singles hitter has a high average and the power hitter doesn't. Ends up just dipping into altered (corked) bats; would love to read more modern research into this. A short, interesting and basically timeless book.
