Justin's Reviews > The Book: Playing the Percentages in Baseball

It's a little dry at times, zooming through some of the math with the assumption that the reader's pretty able to follow without much explanation (this is often true), but it's insightful. Of special value is the application of game theory to typical SABR research. Largely because of this aspect, the book frequently refutes not only conventional wisdom (though less often that you might expect), but also "conventional sabermetric wisdom." The book gives adequate credit to managers for doing their job properly in instances where SABR people might disagree.

Worth it for the sections on batting order optimization, sacrifice bunting (which involves far more nuance and consideration than I've seen elsewhere) and game theory.
